In the context of hyperbaric chamber purchase, “2 person hyperbaric chamber” first expresses a crew capacity: two people can be accommodated in the same chamber at the same time. It is merely a capacity description and does not constitute a separate engineering grade, safety grade, or regulatory category. People who want to buy a double cabin often focus on “whether they can fit two people”, which can easily lead to missing details that really affect the user experience and safety.

Two-person capacity is not equal to the uniform specification

Also two person hyperbaric chamber, the differences between different brands and structures can be very large. The manufacturer writes “two-person” in the promotion, which usually only indicates the direction of the rated passenger, and does not specify whether the “two people” are two adults, one adult plus one child, or whether there is a need for an escort or operator position in the cabin. The rated number of people in a multi-person cabin needs to be distinguished between patients, accompanying persons and cabin staff, and cannot be judged solely by the number of seats. The nominal “2 person” cannot replace the three data points of internal dimensions, rated load capacity and seating layout. Before buying, be sure to check the specific model document, rather than just focusing on a general capacity term.

Soft double cabin selection

On the soft compartment side, models that can accommodate two people are usually made of TPU, which is lighter and foldable overall, and easier to deploy in homes, gyms or small clinics. A representative example is the MC4000 N/U, a multi-person soft cabin that can accommodate two people at the same time. It features a U-shaped or N-shaped zipper structure and an enlarged entrance for wheelchair access. Its pressure specifications are 1.3 ATA or 1.4 ATA, its cabin dimensions are approximately 140 cm long, 130 cm wide, and 175 cm high, and the entire machine weighs approximately 18 kg.

In addition to the combination of two adults, some software models define “two people” in more detail. The extended ST901 can accommodate one adult and one child lying down at the same time, while the extended ST2200 can accommodate one adult and one child sitting together, or in a sitting or reclining position. This kind of “one big, one small” combination is common in home scenarios, and it also reminds us that, again, the hyperbaric chamber 2 person is not the same in terms of the actual objects it accommodates. Before placing an order, you should confirm whether you need two adults or a configuration shared by parents and children.

Selection of a double-hull cabin

If the demand points to a rigid pressure-bearing structure, then two-person hard shell hyperbaric chamber equipment usually uses medical-grade stainless steel as the cabin body and belongs to the category of multi-person cabins. Taking the HE5000 series as an example, the HE5000 offers four interior layouts: two-seater, three-seater, bed board, and bench. The HE5000 Fort adopts a face-to-face seating layout. Both are hardware cabins that can accommodate multiple people and have a pressure specification of 2.0 ATA. These models support customization options such as colors, logos, power seats, starry sky tops, and ambient lighting, and have more room for choice in appearance than soft cabins.

It should be noted that the word “luxury” appears very frequently in the sales context. Some people will look for 2-person luxury hyperbaric chamber and think of it as a more advanced category. In reality, luxury is merely a marketing-level expression of comfort; it cannot replace hard information such as materials, pressure, oxygen supply method, safety, certification, or comfort metrics. A two-person hardware cabin with a starry sky roof and ambient lighting, and a simple two-person cabin, should be checked separately in terms of pressure structure, rated pressure, and compliance documents. Just because they have the word “luxury” on them does not mean that the former is safer and has higher performance.

What to check when making a purchase

Multi-person cabins usually use compressed air to pressurize the cabin body, and then supply oxygen to the user through masks, hoods and other devices. This may be different from the oxygen supply method of single-person cabins and needs to be confirmed in conjunction with the specific model. In addition to the oxygen supply interface, it is also necessary to verify whether the rated crew includes staff, the cabin emergency evacuation plan, the internal space and seating layout, and whether the equipment truly meets the market approval and intended use of the target market. Home scenarios are particularly prone to a misconception: the assumption that loading multiple cabins into a residence automatically reduces requirements for crew, staffing, fire protection, or emergency response. In reality, these requirements will not disappear just because the installation location becomes home.

Additional precautions for home use

Leaving a two-person hyperbaric chamber at home also means re-evaluating the environment. Children, pets, debris, loose wires, and control components that may be accidentally touched all increase the risk of use; background noise may also obscure the alarm sound of the device. Operators need to be able to continuously observe the situation inside the cabin, hear alarms, and maintain communication with the cabin. In addition, even if the soft double cabin can be folded, its entire system still consists of the cabin body, air compressor, oxygen generator and cooling equipment. The deployment conditions must be evaluated according to the entire system, and it cannot just be seen whether the cabin body itself can be stuffed into the room.

Overall, “2 person” is a useful starting point that can help you quickly circle your candidates, but it can never replace a one-by-one check of interior dimensions, load ratings, seating layout, oxygen delivery methods, and compliance documentation. Treat the capacity word as a screening condition and the model document as the basis for decision-making. Only in this way can the selected double cabin truly suit the users and usage environment of your home.

Understand what the concept of “2 atmospheres” is

When we see “2 atmosphere hyperbaric chamber”, our first reaction is: Is this absolute pressure or gauge pressure? Many times we see the word “ATA”, which is absolute atmospheric pressure (atmospheres absolute), which is calculated using absolute vacuum as zero. In other words, 1 ATA is a standard atmospheric pressure in itself, not an additional atmospheric pressure added to the ambient pressure.

If a device’s parameter knot says 2.0 ATA on the ground, that translates to an absolute pressure of 202.65 kPa, which is almost equal to 29.3918 psia. If calculated at standard sea level, the cabin actually increased by approximately 101.325 kPa (about 14.6959 psig) compared to the outside. Of course, real-world environmental pressures are related to your altitude and weather, and must be calculated according to local conditions.

So, whether it’s called “2 atm”, “2.0 ata”, or “2 atmospheres”, we can only be comparable on the same “absolute pressure” channel. If the specification sheet you get simply says “2 atmosphere” or “psi”, but doesn’t specify whether it is absolute pressure, gauge pressure, normal operating pressure, or maximum allowable pressure, then this data is basically a fool’s errand, and it is impossible to determine the actual operating status of the equipment.

Don’t just stare at a pressure number, look at the full set of specifications

When buying an oxygen tank, the normal operating pressure, the maximum allowable operating pressure, and the set pressure of the pressure relief valve must be confirmed one by one. The device is rated to reach 2.0 ATA, which does not mean that you have to constantly withstand this extreme pressure, nor does it mean that everyone’s physical condition can adapt to this pressure.

Also, don’t assume it must be a medical device just because the name is high-sounding. A typical “hyperbaric chamber” is just a chamber that can increase pressure and allow people to enter; if “oxygen” (hyperbaric oxygen chamber 2.0 ata) is added, it means that it has the function of supplying oxygen in a high-pressure environment. As for whether this machine can be used for certain clinical purposes, it also depends on what breathing gas it uses, the manufacturer’s stated intended use, whether it has all the relevant model qualifications, and specific operating instructions. One “2.0 ATA” alone says little.

It is also 2.0 ATA, how to choose the cabin structure?

Taking products under MACY-PAN (Shanghai Baobang) as an example, the models marked as 2.0 ATA are actually hardware cabins, but the difference is huge in how they go in, sit or lie down, and can accommodate several people.

For example, the HP2202 is a horizontal hardware cabin made of medical-grade stainless steel, 220 cm long, and available in three diameters: 75, 85 and 90 cm. Its sibling, the HP2202 DIA, is also designed for lying down, but it has an extra-large transparent viewing window, is also 220 cm long, and has diameters of 90 and 100 cm.

If you want to experience it while sitting, you can check out the HP750. This is a single-seat hardware cabin, 200 cm long, 96 cm wide and 160 cm high, with plenty of space. If you need a single cabin that you can walk right into, the HE5000 Mono with a transparent walk-in hatch is a good fit. As for scenarios with multiple users, you can choose between HE5000 Fort, HE5000 and HE5000 Plus, where you can arrange two seats, three seats, benches or even bed boards according to the number of people. The HE5000 Plus can accommodate up to four people at the same time.

You see, although everyone has the “2.0 ATA” label on their heads, whether it is horizontal, seated or walk-in, single or multi-person, the size of the door and the layout inside directly determine whether the device is easy to use, how much space it takes up, and how to operate it normally.

Buying an oxygen chamber is buying a whole system

A hyperbaric oxygen chamber is not just an iron shell. A complete system consists of the cabin, air compressor and oxygen concentrator working together: the air compressor is responsible for injecting filtered air to increase the pressure, the automatic valve stabilizes the pressure, and the oxygen concentrator then supplies oxygen-enriched gas into it.

Moreover, the different models come with different “three major parts”. For example, the HP2202 is equipped with an all-in-one unit and a regular air conditioner; and the HP2202 DIA not only has an all-in-one unit, but also a special high-efficiency air cooling system. Therefore, when comparing prices, keep your eyes open and make sure to confirm whether the manufacturer’s quotation sheet has rounded the cabin, control console, pressurization pump, oxygen generator, air conditioning equipment and various accessories. If you just stare at the size or pressure of the cabin, you will easily end up dumbed down ——for example, the total weight of the system is too heavy, the area occupied is too large, or the power supply, ventilation and even later maintenance conditions are not taken into account in advance.

Before placing an order, understand the installation site

When looking at the size chart, you must clearly distinguish several data points: how much usable space is inside, how much land is occupied outside, how much total land the entire system occupies, and the packaging and transportation dimensions. Don’t forget to measure the door width, door height, threshold height, which side the door opens to, and the space required to open the door in your venue. Recumbent cabins focus on internal length and diameter; seated or vertical cabins also need to consider whether the seats are wide enough, whether the legs can be extended, whether the top of the head will be suppressed, and whether the movement of people in and out is comfortable and uncomfortable.

Before the equipment enters the area, you have to step on the entire transportation channel. The door width is not wide enough, whether the corner can be turned, whether the floor slab can bear the load, whether there is power supply and grounding, whether the ventilation is good, whether the fire protection cannot be closed, whether there is sufficient maintenance spacing around, whether it is good to evacuate in an emergency… These all need to be implemented item by item.

Especially with the load-bearing floor slabs, the weight span of the hardware compartments is outrageous! For example, the HP2202 is about 150, 160 or 180 kg according to specifications, but once it is replaced with HP750, the weight will directly soar to 1000 kg. Don’t assume that the size can fit through the door. The biggest problem is whether the floor can be pressed down or who can carry it.

Strictly adhere to the safety bottom line corresponding to the model

How to use the cabin after purchase and how much operating pressure to set must be closely monitored in the manufacturer’s instructions for the specific model. The general conversions mentioned above are just to give you a sense of purpose and should never replace the actual calibration, operating procedures, or professional solutions of the equipment. During operation, people must be kept outside to keep an eye on the user as required throughout the entire process to keep the call smooth and respond immediately if there is any abnormality.

There’s also a red line: oxygen-rich environments are extremely flammable! Any electronic products, clothing, care products, or cleaning materials entering the cabin must be confirmed to be safe for use in a high-pressure, oxygen-enriched environment. As long as the manufacturer does not specify permission, you must never add oxygen sources, change pipelines or dynamic and electrical devices yourself. When using it, if you encounter an alarm going off, cabin damage, air leakage, smell an odor, hear unusual noises, or control failure, don’t think about anything. Immediately stop the machine according to the instructions and contact the manufacturer or qualified service provider.

Final verification before paying

To summarize, when you’re in the eye for a device marketed as a “hyperbaric chamber 2.0 atmospheres”, at least match these numbers on your checklist: specific model, what caliber the pressure standard is, normal operating pressure and maximum permissible pressure, cabin structure type, number of people, and posture. In addition, it is necessary to find out the internal and external dimensions, what the complete system includes, whether the installation conditions are sufficient, whether there is an instruction manual, and whose responsibility is the after-sales service.

Only when these details are fully implemented in black and white in the specific model and written documents will “2 atmosphere hyperbaric chamber” cease to be a broad name and truly become a set of equipment solutions that can be compared horizontally, installed on the ground, and managed reliably.

Pressure caliber determines everything

In the parameter table of the hyperbaric oxygen chamber, atm, ATA and psi are the three most common pressure expressions, but their meanings are not the same. A standard atmospheric pressure is represented by the symbol atm, which is exactly equal to 101.325 kPa, or approximately 14.6959 psi. ATA is an abbreviation for atmosphere absolute, which refers to the absolute pressure calculated from the absolute vacuum point. 1. ATA represents the absolute pressure of a standard atmosphere; it does not mean an additional atmosphere above the ambient atmosphere. The daily environment at sea level is already under pressure conditions of approximately 1 ATA.

2 atm What is the pressure

To understand the expression 2 atm hyperbaric chamber, you must first distinguish between gauge pressure and absolute pressure. Gauge pressure is the difference between the measured pressure and the local ambient atmospheric pressure. The absolute pressure is equal to gauge pressure plus local ambient atmospheric pressure. If the same device is written in two different calibers, the values will differ by a full atmosphere. The absolute pressure converted from 2.0 ATA is 202.65 kPa, which is approximately equal to 29.3918 psia; under standard sea level conditions, it corresponds to a gauge pressure of 101.325 kPa, or 14.6959 psig. Therefore, when you see a writing like 2 atm or 2 atmosphere hyperbaric chamber, you need to first confirm whether the other party is referring to 2.0 ATA absolute pressure or 2 atm gauge pressure. The two differ by one atmosphere of pressure, and the exposure conditions for falling on the user are completely different.

Conversion comparison of common specifications

The importance of caliber becomes clearer when looking at several common specifications side by side. 1.3 ata hyperbaric chamber corresponds to an absolute pressure of 131.7225 kPa, approximately 19.1047 psia, and a gauge pressure of approximately 30.3975 kPa and 4.4088 psig at standard sea level. 1.4 ata hyperbaric chamber corresponds to an absolute pressure of 141.855 kPa, approximately 20.5743 psia, corresponding to a gauge pressure of 40.53 kPa and 5.8784 psig. 1.5 ata hyperbaric chamber corresponds to an absolute pressure of 151.9875 kPa, approximately 22.0439 psia, corresponding to a gauge pressure of 50.6625 kPa and 7.3480 psig. Further up, the 2 ata hyperbaric chamber and the 2.0 ata hyperbaric chamber point to the same 2.0 ATA gear, corresponding to an absolute pressure of 202.65 kPa, approximately 29.3918 psia. Specifications such as 2.4 ata hyperbaric chamber and 2.5 ata hyperbaric chamber have fallen into the commonly used clinical pressure range of 2.0 to 3.0 ATA.

psi also needs to be distinguished by caliber

The pit of psi is the same as atm, and writing only psi cannot indicate the reference zero point. When you encounter a description like hyperbaric chamber 12 psi, you also need to ask whether it is psia or psig. The psia uses absolute vacuum as the zero point, and the psig is the gauge pressure relative to the local ambient atmospheric pressure. If a chamber labeled 12 psi refers to the psig, the absolute pressure is one atmosphere higher than that of the 12 psia. The specification sheet should indicate the maximum permissible working pressure, normal working pressure, and pressure relief device setting pressure separately, and should not leave only an isolated number.

Higher pressure does not necessarily mean more appropriate

When purchasing a hyperbaric oxygen chamber, higher pressure does not automatically mean that the equipment is more suitable, more effective, or safer. 2.0 ATA is a threshold in the current clinical definition of hyperbaric oxygen, which usually requires breathing medical-grade oxygen at a pressure of not less than 2.0 ATA in the hardware compartment. The commonly used clinical pressure range falls between 2.0 and 3.0 ATA. 1.3, 1.4, 1.5 Low-pressure devices such as ATA cannot be selected as clinical hyperbaric oxygen therapy devices based solely on their pressure name. The target pressure must be assessed together with the equipment’s intended use, structural design, oxygen supply method, operating instructions, and professional supervision requirements.

Correspond 2 atm to the specific product

From the actual product perspective, requirements such as hyperbaric chamber 2 atm or hyperbaric chamber 2 atmospheres often ultimately correspond to a hardware compartment rated at 2.0 ATA. Common specifications for soft pods are concentrated in 1.3 to 1.5 ATA, while 2.0 ATA models generally use steel or stainless steel hardware structures. When selecting a model, if you hear the terms hyperbaric chamber 2 ata, hyperbaric chamber 2.0 ata, or hyperbaric chamber 2.0 atmospheres, you need to verify them all against the caliber of 2.0 ATA absolute pressure and further confirm the three data: normal operating pressure, maximum allowable operating pressure, and pressure relief device setting pressure.

Oxygen in name does not change the verification method

At the terminology level, hyperbaric oxygen chamber is written with oxygen. Compared with hyperbaric chamber, it only emphasizes the oxygen supply in the cabin, and the pressure caliber is checked in the same way. For example, the difference between hyperbaric oxygen chamber 1.5 ata and 2.0 ata hyperbaric oxygen chamber lies in the two absolute pressure values of 1.5 and 2.0. Conversely, 2.0 hyperbaric chamber, which lacks a stress unit, is only comparable if it is clearly 2.0 ATA and states whether it is work stress, treatment stress, or an upper limit. There is an absolute pressure difference of 0.5 ATA between the hyperbaric chamber 1.5 ata and the hyperbaric oxygen chamber 2.0 ata, corresponding to a gauge pressure difference of approximately 50.66 kPa. This difference cannot be ignored.

When many people mention hyperbaric oxygen chambers, the first thing that comes to mind is the long, reclining chamber. People lie flat in it, and the pressure slowly rises after the door is closed. In fact, hyperbaric oxygen chambers are not limited to lying down; both seated and vertical designs are equally mature. A hyperbaric chamber used in a seated position is often called a sitting hyperbaric chamber, or seated hyperbaric chamber. Their common feature is that they keep the user in a sitting or semi-sitting position to complete pressurization and oxygen supply. This form is particularly friendly to people who cannot lie flat for a long time or who want to read and work during use.

In industry terminology, sitting, segmented, and sit-up usually refer to the usage structure of sitting or semi-sitting, while sit down emphasizes the entry and usage method of sitting down. Whether you see a sit-up hyperbaric chamber or a sit-down hyperbaric chamber, it refers to the same type of product: a person remains seated in the cabin to complete pressurization and oxygen supply. A word order like “hyperbaric chamber sitting” expresses the same concept as “sitting hyperbaric chamber”. The vertical hyperbaric oxygen chamber describes the vertical layout of the cabin, and users basically sit in the cabin, which is significantly different from the common horizontal cabin.

2. How to understand the pressure of ATA

ATA is an abbreviation for atomspheres absolute, which represents the absolute pressure at which absolute vacuum is zero. 1 ATA is equal to one standard atmosphere, which is 101.325 kPa; then 2.0 ATA is the absolute pressure of 202.65 kPa, which is about 29.39 psia. Under sea level conditions, a gauge pressure of 2.0 ATA corresponds to approximately 14.70 psig. Here we need to distinguish between absolute pressure and gauge pressure. Once the same pressure value is mixed with two calibers, it will appear that there is a full difference of one atmosphere.

It should be noted that higher pressure does not automatically mean that the device is more suitable, more effective, or safer. In a sit-down cabin, the operating pressure of soft sit-down models is usually between 1.3 and 1.5 ATA. A sit-down cabin that truly achieves a pressure of 2.0 ATA is often a hardware structure. The reason is also direct: to stably support a pressure differential of 2.0 ATA over a long period of time, a rigid shell is more reliable than a flexible fabric.

Soft and hard seating

If you are on a budget or value portability and storage, a portable sitting hyperbaric chamber is more suitable. Soft-sitting cabins are made of flexible materials and are foldable and lightweight, making them suitable for use in homes, gyms, or small clinics; some models are equipped with adjustable folding chairs that allow users to sit and recline. However, its pressure specification is usually between 1.3 and 1.5 ATA, and does not reach 2.0 ATA.

If the goal is 2.0 ATA, then we should basically look at the hardware-sitting cabin. The sitting hard shell hyperbaric chamber uses a rigid pressure-bearing shell, and the user remains seated in the cabin; when it uses medical oxygen as its breathing gas, it can also be called a sitting hard shell hyperbaric oxygen chamber. These types of cabins have a large deadweight and occupy a fixed area. They usually need to confirm the site load-bearing capacity and transportation path first, but their advantages are a higher pressure limit and a more stable structure. Hard-seat cabins often adopt a vertical compact structure, and the width design will try to take care of the regular doorway to reduce the space occupied.

Which parameters should be checked when purchasing

Regardless of which type is chosen, the suitability of a sit-in cabin depends on several key parameters: seat width, legroom, headroom, entry size, and seat adjustment range. There are also some particular entrance methods, some using zipper entrances, and some using enlarged entrances to facilitate direct wheelchair access. When making a purchase, you cannot just focus on the pressure number; you must also evaluate the structure type, oxygen supply method, usage environment, and professional supervision requirements together.

Overall, the 2 ATA seated hyperbaric oxygen chamber corresponds to a seated or vertical chamber with a rigid shell and a pressure of 2.0 ATA. It is two different levels from the soft seated chambers with 1.3 to 1.5 ATA. Before purchasing, check the absolute pressure caliber, structural type and cabin space parameters clearly before choosing the one that is truly suitable for you.

When looking through the specifications of a hyperbaric chamber (Hyperbaric Chamber), it is easiest to get dizzy at “pressure value”. If you’re staring at a device labeled 2.0 ATA and ready to shell out the cash, don’t rush. Taking a few minutes to get through the following can save you a lot of money and even save your life.

What exactly is 2.0 ATA? Don’t be fooled by math problems

Many people think that 2.0 ATA is simple “with double the pressure”, but it is not. This “A” in 2.0 ATA represents absolute pressure (Absolute). It is zero with absolute vacuum.

The atmospheric environment we live in has 1 atmosphere of pressure. So, when a cabin advertises that it can reach 2.0 ATA, the pressure gauge on its door actually shows only about 101.325 kPa (or 14.7 psig).

Why do we have to stick with the number 2.0? Because it is a “hard threshold” for clinical treatment. According to the official UHMS (Undersea and Hyperbaric Oxygen Society), true clinical hyperbaric oxygen therapy typically requires a pressure jump of 2.0 ATA and requires breathing medical-grade oxygen in a hard compartment. If the pressure is insufficient, it may just be a high-end “health pod” and not clinical treatment.

Is the “2.0” in the sales mouth absolute pressure or gauge pressure?

When consulting customer service or sales, don’t ask about the price in the first sentence. Ask this first: “Does your 2.0 refer to absolute pressure or gauge pressure?”

The difference between the two algorithms is a full atmosphere (almost 14.7 psi). Some manufacturers like to play word games, using the gauge pressure as absolute pressure. If you believe me, the pressure capacity of the equipment you buy back may be greatly reduced. Taking 1.5 ATA and 2.0 ATA, it looks like a difference of 0.5, but the material strength requirements and structural design behind it are completely two orders of magnitude. Remember: stress levels are not numbers that are better, but if you’re looking for clinical results, the numbers have to be realistic.

Remember this: 2.0 ATA has almost no “soft”

This is common sense in the industry: what can withstand the pressure of 2.0 ATA can basically only be a hardware cabin (Hard Chamber).

These cabins are typically made of medical-grade stainless steel. Whether it’s lying down, sitting, or a walk-in for multiple people like a small room, the material must be firm enough as long as the pressure reaches the 2.0 level.

Single hard cabin: You can either inflate the cabin directly with oxygen or inflate it with air and then put on a mask.

Multi-person hard cabin: To prevent fire, the cabin must be filled with compressed air, and oxygen must be given separately through a breathing mask.

There’s a big pit here: those fabric, plastic “software pods” or “portable pods” on the market typically have physical limits between 1.3 and 1.5 ATA. If someone sells you “a 2.0 ATA soft oxygen chamber”, listen to me and just block it. This kind of cabin, forced to pressurize, is not only useless, but also like a time bomb that could explode at any moment.

Before talking about money, check whether the configuration is correct

The price range for the 2.0 ATA hardware compartment is very wide. It’s meaningless to just look at the reserve price; it depends on what you’re buying.

Let’s go through the current market accepted price:

Horizontal hard cabin with a diameter of 75cm: about US$40,000;

85cm diameter: Quotes usually jump to around $47,000;

The spacious version with a diameter of 90cm: I can hardly take it without 50,000 US dollars.

These prices typically bundle a 10L oxygen concentrator, integrated air conditioning, or a high-efficiency cooling system. If the diameter difference is 5 centimeters, the price difference could be several thousand. So when comparing prices, you have to put the pressure caliber, cabin structure, supporting appliances, and even after-sales service on a plate, otherwise you think you got a bargain, but you actually bought an “empty shell”.

The “life-saving” list before placing an order cannot be missing

To get this 2.0 ATA big thing to land safely, you have to ask the manufacturer for these things. Don’t be fooled by a few refurbished promotional pictures:

Check ID: To enter the US market, you must have an FDA 510(k) record and the product code must be CBF. Also, to understand the difference between FDA Approved (approved) and 510(k) Cleared (licensed), these are two different things and the legal liability is far less.

For the main party: Who signed the contract? To whom should the money be given? Who will repair it after the sale? Don’t let the machine get stuck in its slump, the sales are missing, and no one can even come to the door to drive screws.

Get the cards: Before paying the deposit, you must have the formal quotation (official quotation), technical specification sheet, installation environment requirements, fire protection information, and other paper documents.

One last nag: When buying a hyperbaric oxygen chamber, performance always comes before price, and qualifications always come before advertising. Without hardware and compliance certifications, even the cheapest “2.0 ATA” is nothing more than an expensive inflatable toy.

2 ATA represents the amount of pressure

Let’s first clarify what a value 2 ATA is. The full name of ATA here is atmospheres absolute, which is commonly referred to as “absolute pressure”. It is calculated using absolute vacuum as zero. One ATA is exactly one standard atmosphere (101.325 kPa). So, if you see a device labeled 2 ata hyperbaric chamber, or called hyperbaric chamber 2 ata, the meaning is actually very simple: this chamber can pressurize the absolute pressure inside to 2 atmospheres, which is 2.0 ATA.

It might be more intuitive to say the specific points. The absolute pressure of 2.0 ATA is approximately 202.65 kPa, which translates to about 29.39 psia. Normally, people often check the instrument “gauge pressure” (the number left after the pressure in the cabin is reduced by the atmospheric pressure outside). Under sea level standards, the gauge pressure of 2.0 ATA is about 14.70 psig. To put it bluntly, about 1 atmosphere of pressure was added to the original atmospheric pressure.

It’s very easy for people here to make misunderstandings. 2 ATA says there is an absolute pressure of 2 atmospheres “in total”, not an additional 2. At sea level, it simply adds an extra atmosphere of pressure. This is the same logic as the 1.5 ATA algorithm. Therefore, when looking at equipment parameters, you must always keep an eye on whether it is marked with ATA (absolute pressure), psia, or psig. These three cannot be confused.

What is the difference between it and 1.3, 1.4, and 1.5 ATA

As soon as the pressure parameters change, the cabin structure basically needs a major overhaul. Take the MACY-PAN (Madis) product line that everyone is more familiar with. Their soft cabin uses flexible fabric and cannot withstand too high pressure. So whether you buy a soft cabin for single lying or sitting, the pressure limit is basically at the three gears of 1.3, 1.4, and 1.5 ATA. If you search for 1.3 ata hyperbaric chamber, 1.4 ata hyperbaric chamber or 1.5 ata hyperbaric chamber on the market, you will actually find these types of software pods. Even if someone uses a different search method and uses hyperbaric chamber 1.5 ata or hyperbaric oxygen chamber 1.5 ata, they are still referring to this low-pressure fabric cabin.

What does it really look like to achieve 2.0 ATA? They are basically all hardware compartments. Only by using hard engineering materials such as stainless steel as the outer shell can it withstand such a large pressure difference. You find that no, the difference between 2 ATA and 1.5 ATA is not just the pressure value of 0.5, but also a watershed between “soft” and “hard”. But then again, high pressure doesn’t mean it’s absolutely good or absolutely safe. Which gear to choose depends on what you are buying it for and whether you have the conditions to store a hardware compartment at home.

Several different ways to write pressure

When looking up information online, the various ways of writing 2 ATA can definitely make people dizzy. There are those that say 2 atm hyperbaric chamber, there are those that say 2 atmosphere hyperbaric chamber, and there are even those that say hyperbaric chamber 2 atmospheres or hyperbaric chamber 2.0 atmospheres backwards. No matter how they change their names, just remember this: atm, atmosphere, and ATA can only be directly equated when the merchant explicitly states that this is “absolute pressure”. In case the seller reports “gauge pressure”, the absolute pressure calculated from the 2 atm gauge pressure has soared to 3 atmospheres, which is a huge difference between the two concepts.

In addition, if you encounter a type of person who simply writes a number without even a unit, you need to be more careful. For example, in the 2.0 hyperbaric chamber, there is no unit and no attributes are indicated. You have no idea whether this “2.0” refers to daily work stress, maximum limit or treatment stress. There is another type that likes to use psi as the unit, such as the hyperbaric chamber 12 psi, where 12 psi generally refers to the gauge pressure. We calculated that the gauge pressure of 2.0 ATA is about 14.7 psig. You’ll understand by comparing them this way: 12 psi is still far from the standard of 2.0 ATA. In short, if you see that it only writes psi, ask clearly whether it is psia or psig first, and then convert it with ATA after you understand it.

Then take MACY-PAN as an example. Everything they can get to 2.0 ATA is a hard shell. For example, the reclining cabin has a 2.0 ata hyperbaric chamber specification. The outer shell is made of medical-grade stainless steel and is available in three diameters: 75, 85, and 90 cm. If you’re afraid of boredom, there are also those with extra-large transparent windows, with a diameter of 90 or even 100 centimeters. If you prefer to stand upright, they have a single-seat cabin with an iron shell that is 96 cm wide, which is just the right width to push through the door of a regular room in your home. For example, the HE5000 series, whether it is a single cabin that people can walk into directly or a large cabin that can seat four people, is designed in accordance with the 2.0 ATA standard. The market calls them hyperbaric chamber 2.0 ata, or hyperbaric chamber 2 ata. They actually describe these kinds of strong, rigid ballast tanks.

In contrast, the limit of the soft compartment is 1.5 ATA. Don’t be fooled by some businesses packaging their names in a fancy way, with the word “2.0”, it won’t just become a hardware cabin out of thin air. So the next time you come across specifications like hyperbaric chamber 2.0 ata online, take a look at the cabin materials and pressure-bearing structure. Find out whether it is soft or hard, so as not to spend a lot of money and end up moving a low-voltage software cabin home as a 2.0 ATA hardware cabin.

2.0 Relationship between ATA and clinical hyperbaric oxygen

In true medical clinical circles, 2.0 ATA is a very hard threshold. There is now a strict medical definition of clinical hyperbaric oxygen therapy: patients must enter a hard compartment that meets the dual national standards of pressure and fire protection, the pressure cannot be lower than 2.0 ATA, and the oxygen inhaled must be medical-grade pure oxygen. Treatment pressure in general hospitals is between 2.0 and 3.0 ATA. Therefore, only devices of this level, such as the 2.0 ata hyperbaric oxygen chamber or the hyperbaric oxygen chamber 2.0 ata, can be considered to have touched the edge of clinical standards in terms of hardware. As for the soft cloth cabins of 1.3 to 1.5 ATA, they cannot reach this line.

If we focus on the range of 2.0 to 3.0 ATA, even 2.4 ata hyperbaric chamber or 2.5 ata hyperbaric chamber can be considered a relatively intense treatment pressure, which usually requires a very strict clinical environment and professional medical staff to keep an eye on. However, don’t assume that the machine can hit 2.0 ATA; it should be a stage “clinical hyperbaric oxygen chamber”. This is not that simple. You also have to see whether it has a hardware structure, whether it can receive medical oxygen, whether it has passed relevant regulations, and whether there are professional personnel to manage it. All of these are indispensable.

What to pay attention to when purchasing and using

If you have already decided to buy the 2.0 ATA grade, be sure to ask about the pressure caliber and cabin material before paying. Don’t let a single ATA number replace all the parameters. In addition to the nominal pressure, you also need to check what the normal operating pressure is, what the maximum permissible pressure is, and whether the pressure relief valve is set to an unsafe value. Not only that, the hardware cabin is usually a complete set of large systems. All integrated units, air conditioners or high-efficiency cooling systems must be equipped. The installation requirements for the home are completely different from those for the software cabin.

When I got it home and started using it, I couldn’t press the hardware compartment of the 2.0 ATA blindly; I had to follow the instructions for the specific model honestly. When the machine is running, it’s best to have someone knowledgeable watching. Before entering the cabin, you cannot bring in any unlicensed electronic products or items that are prone to static electricity. It’s time to clean and inspect, and it’s time to conduct safety inspections. The ultimate goal of buying cabins is to clarify the pressure, identify the structure, understand the purpose, and finally determine the compliance status. After understanding all these points, the 2 ATA cabin you bought is not wasted money and you can use it with real confidence.

What is a soft hyperbaric oxygen chamber

High-pressure oxygen chambers are roughly divided into two categories according to their pressure-bearing structure. One type uses a rigid shell to bear pressure and belongs to the hard cabin; the other type uses flexible fabric materials to make a closed cabin and belongs to the soft cabin. The term “soft” corresponds to the latter. It is also commonly called “fabric”, “inflatable” or “portable hyperbaric chamber” on the market, which actually refers to the same flexible pressure-bearing structure. The benefits of a soft cabin are intuitive: the cabin can be folded and stored, is lightweight, and can be used in a home environment with an air compressor and oxygen concentrator, taking up relatively little space.

How much pressure does 1.5 ATA represent

The 1.5 ATA marked on the soft compartment refers to the absolute pressure inside the compartment. ATA is an abbreviation for atmosphere absolute, calculated based on the absolute vacuum zero point; 1 ATA is a standard atmospheric pressure, equal to 101.325 kPa. Based on this benchmark, the absolute pressure of 1.5 ATA is 151.9875 kPa, which is approximately 22.04 psia. Changing to gauge pressure is more intuitive. Gauge pressure is the difference between the cabin pressure and the local atmospheric pressure. Under standard sea level conditions, 1.5 ATA corresponds to a gauge pressure of approximately 7.35 psig, which is equivalent to adding about half an atmosphere of pressure above atmospheric pressure.

A misunderstanding is likely to arise here. 1.5 ATA refers to an absolute pressure of 1.5 atmospheres in total, rather than an additional 1.5 atmospheres added to the normal atmospheric pressure. This is why when looking at the soft compartment specifications, it is essential to distinguish between ATA absolute pressure, psia, and psig calibers; they cannot be directly compared.

Pressure limit of the soft compartment

The soft cabin is supported by fabric, and the upper pressure limit is naturally lower than that of the hard cabin. Taking the MACY-PAN’s soft cabin as an example, the pressure specifications of both the single-person recumbent and seated soft cabins cover three gears: 1.3, 1.4, and 1.5 ATA. 1.5 ATA is exactly the upper edge of this section of the soft cabin. The cabin is made of TPU. The single-person horizontal cabin weighs about 13 kilograms and is about 220 centimeters long and 80 centimeters in diameter when unfolded. The diameter of the widened horizontal cabin is increased to about 90 centimeters. Seated cabins are available in compact models with L-shaped zippered entrances, as well as models with adjustable folding chairs that can be used for sitting or reclining, and generally weigh between 12 and 16 kilograms.

There is one thing that needs to be made particularly clear here. While learning about the product, I occasionally see the term 2.0 ata soft hyperbaric chamber, which literally means a software compartment that can reach 2.0 ATA. However, according to MACY-PAN’s product line, the rated pressure of the soft compartment is as high as 1.5 ATA. Those that are truly designed according to 2.0 ATA are all stainless steel shells and hard compartments that need to be fixedly installed. The soft cabin uses flexible fabric as the pressure boundary, and the pressure ceiling is lower than that of the hard cabin. Therefore, when you see a combination of 2.0 ata soft hyperbaric chamber, it is worth checking the pressure specifications and cabin structure of the specific model to confirm whether it is software or hardware.

Differences between 1.5 ATA soft chamber and clinical hyperbaric oxygen

Soft cabins fall under the category of low-pressure cabins. There is a clear definition threshold for clinical hyperbaric oxygen therapy: patients must breathe medical-grade oxygen at a pressure of not less than 2.0 ATA in a hard compartment that complies with the corresponding pressure vessel and fire safety regulations. Common clinical treatment pressures are between 2.0 and 3.0 ATA. Exposure to air pressure below this threshold is generally not included in the definition of therapeutic hyperbaric oxygen.

Therefore, a 1.5 ATA soft chamber, with or without oxygen or HBOT in its name, cannot be used as a clinical hyperbaric oxygen therapy device based solely on pressure numbers. Its value falls more on non-clinical scenarios such as daily family life, exercise recovery, relaxation and stress reduction. When making a purchase, don’t be obsessed with the higher the pressure, the better: higher pressure does not automatically mean better fit, better results or safer. The key is to see if it matches your actual use.

What to check when selecting a 1.5 ATA software cabin

After locking the 1.5 ATA software bay, there are a few things worth confirming item by item. In terms of pressure, in addition to the number 1.5 ATA, we also need to look at the normal operating pressure, the maximum allowable operating pressure, and the set pressure of the pressure relief device. Do not let one number replace all parameters. In terms of structure, it is necessary to confirm the cabin materials, number of layers, valves and pressure resistance range. Different soft cabins are different in these details. In terms of supporting facilities, the soft cabin is actually a system, which usually works together with the cabin, air compressor and oxygen generator. The oxygen concentration provided by the oxygen generator is generally above 93%, and it also needs to be equipped with an air cooler. In terms of posture, the reclining position is suitable for lying down, and the sitting position is suitable for people who want to sit or lean back. You can choose according to your own usage habits.

Safety points in use

When using the soft compartment, follow the instructions for the specific model and do not change the pressure setting on your own. An environment with high oxygen concentrations will increase the risk of fire. During operation, pay attention to ventilation, fire protection and grounding, and do not bring electrical or electrostatic items into the cabin that are not permitted by instructions. During use, compliant personnel should continuously monitor the equipment, and the equipment should also undergo cleaning, maintenance, and safety inspections according to the manufacturer’s specified cycle. When considering the pressure, structure, purpose and compliance status, a 1.5 ATA software cabin can be truly selected and used with confidence.

Understand the 1.5 ATA number before buying

When you see information like 1.5 ata hyperbaric chamber for sale, your first reaction should not be to rush to place an order. You must first understand this pressure number. ATA is short for atmospheres absolute, which refers to absolute pressure measured at zero point in absolute vacuum. 1 ATA is a standard atmosphere of pressure, with an exact value of 101.325 kPa, which is approximately equal to 14.6959 psi. On this basis, the absolute pressure of 1.5 ATA is 151.9875 kPa, or approximately 22.04 psia.

The easiest pit to step on here is the pressure caliber. Absolute pressure and gauge pressure are two different things. Gauge pressure is the difference between the pressure in the cabin minus the local atmospheric pressure. At standard sea level, a gauge pressure of only about 7.35 psig corresponds to 1.5 ATA. That is, a device marked 1.5 ATA, read with gauge pressure, would only have a few psi left at seven. Conversely, if you look at the hyperbaric chamber 12 psi, 12 is usually read by gauge pressure, which translates to an absolute pressure of about 1.8 ATA up and down, which is actually a fraction higher than 1.5 ATA. The pressure caliber in the specification table is not uniform, which is the easiest part to make mistakes when purchasing.

1.5 ATA is mainly sold in two categories of products

After locking the 1.5 ATA, you’ll find it appearing on both the software and hardware pods’ sales listings. On the soft compartment side, 1.5 ATA is the upper limit of the low-pressure section. Taking MACY-PAN products as an example, the model ST801 is a single-person portable horizontal soft cabin with pressure specifications covering 1.3, 1.4 and 1.5 ATA. The cabin body is made of TPU material, weighs 13 kg, is about 220 cm long and 80 cm in diameter when unfolded, and has a nominal upper noise limit of 45 decibels; the ST901 is its widened version, with a diameter of 90 cm and a weight of 15 kg. This type of cabin can be folded and stored, making it easier to move and store.

On the hardware compartment side, 1.5 ATA is the starting point. The pressure specifications of the stainless steel-based rigid horizontal cabin usually start from 1.5 ATA and are more concentrated in 2.0 ATA; while the vertical and multi-person rigid cabin are basically designed according to 2.0 ATA. So, it is also 1.5 ATA. One may be a soft cabin that can be folded away, and the other may be a fixed stainless steel hardware cabin. The two are very different in structure, oxygen supply method and use. When you see a 1.5 ATA on sale, the first thing to do is to tell whether it is software or hardware.

How to choose 1.5 ATA and 2.0 ATA

When buying a hyperbaric oxygen chamber, many people hesitate between 1.5 ATA and 2.0 ATA. This is actually due to the difference in use boundaries. Clinical hyperbaric oxygen requires patients to breathe medical-grade oxygen in a hard body compartment at a pressure of no less than 2.0 ATA, so 2.0 ATA is a hard threshold for therapeutic hyperbaric oxygen. The 1.5 ATA is still below this threshold. Regardless of software or hardware, the pressure figure alone cannot be used as a clinical treatment module.

If you see specifications like 2 ata hyperbaric chamber for sale, 2.0 ata hyperbaric chamber for sale, or hyperbaric chamber 2 ata for sale when comparing prices, they basically refer to the same 2.0 ATA pressure, just with the word order of pressure and chamber reversed. Looking at these 2.0 ATA pending orders and 1.5 ATA together, the most important thing is to recognize the pressure threshold: 2.0 ATA is the starting point of clinical hyperbaric oxygen, and 1.5 ATA belongs to the common section of low-pressure soft capsules. Which paragraph you want determines which type of pending order you should focus on.

What to check item by item before placing an order

After deciding to buy 1.5 ATA, there are a few things to write down on your checklist. To distinguish whether ATA is absolute pressure, psi is gauge pressure or absolute pressure, it is best to let the supplier give the full conversion. The complete parameters cannot be represented by just one 1.5 ATA figure either, and one device should also indicate the normal operating pressure, the maximum permissible operating pressure and the set pressure of the pressure relief device.

Compliance status is also checked. The U.S. market can query 510(k) records for specific devices by product code CBF and note that 510(k) cleared and FDA approved are two different things. Don’t take the scope of a single 510(k) license and assume it’s being extended to other brands, models, or other uses.

Finally, back to the usage scenario. The software 1.5 ATA cabin needs to be operated according to the specific model instructions, continuously monitored by qualified personnel, and equipped with fire protection and grounding measures in a high-concentration oxygen environment; the hardware cabin needs to verify the installation conditions and professional management requirements. By comparing the pressure, structure, purpose and compliance status, this 1.5 ATA on-sale information is truly understood.

1.5 How much pressure does ATA represent

ATA is short for atmospheres absolute, which refers to the absolute pressure calculated as the absolute vacuum at zero. 1 ATA is a standard atmosphere of pressure, with an exact value of 101.325 kPa, which is approximately equal to 14.6959 psi. On this basis, the absolute pressure of 1.5 ATA is 151.9875 kPa, or approximately 22.04 psia.

Here too, the absolute pressure and gauge pressure should be distinguished. The gauge pressure is the difference between the pressure in the chamber minus the local atmospheric pressure. Under standard sea level conditions, the gauge pressure corresponding to 1.5 ATA is only about 7.35 psig. That is, a device marked 1.5 ATA, read with gauge pressure, would only have a few psi left at seven. Conversely, if you look at the hyperbaric chamber 12 psi, 12 is usually read by gauge pressure, which translates back to an absolute pressure of about 1.8 ATA up and down, which is one cut above 1.5 ATA. Inconsistent pressure calibers are the easiest way to make mistakes when looking at specifications.

1.5 Position of ATA in the pressure ladder

Line up common specifications and the 1.5 ATA will be more clearly positioned. Down below are 1.3 ata hyperbaric chamber and 1.4 ata hyperbaric chamber, which correspond to gauge pressures of approximately 4.4 psig and 5.88 psig, respectively, at standard sea level. These three 1.3, 1.4, and 1.5 ATA gears all fall into the common range of low-pressure soft pods, and 1.5 ATA is exactly the upper edge of this range.

Looking up, the real dividing line is at 2.0 ATA. Clinical hyperbaric oxygen requires patients to breathe medical-grade oxygen in a hardware compartment at a pressure of not less than 2.0 ATA. Therefore, 2 ata hyperbaric chamber, 2.0 ata hyperbaric chamber, 2 atm hyperbaric chamber, 2 atmosphere hyperbaric chamber, and 2 atmosphere hyperbaric chamber, as well as the inverted hyperbaric chamber 2 ata, hyperbaric chamber 2.0 ata, hyperbaric chamber 2 atmospheres, and hyperbaric chamber 2.0 atmospheres, basically refer to the same threshold. The oxygenated 2.0 ata hyperbaric oxygen chamber and hyperbaric oxygen chamber 2.0 ata also fall into this gear. You need to pay attention to the missing unit writing method of 2.0 hyperbaric chamber. You must first confirm whether it is 2.0 ATA or 2 atmospheres of pressure. Further up, there are higher clinical pressure levels such as 2.4 ata hyperbaric chamber and 2.5 ata hyperbaric chamber.

Put 1.5 ATA back on this line, which is at the junction of the soft and hard compartments: downward is the low-pressure area of the pure soft compartment, and upward is the clinical threshold of 2.0 ATA.

1.5 Product form corresponding to ATA

The 1.5 ATA is special in that it appears in the specification sheets on both the soft and hard compartments. On the soft compartment side, 1.5 ATA is the upper limit of the low-pressure section. Taking MACY-PAN’s products as an example, the pressure specifications of the single-person portable horizontal soft cabin cover 1.3, 1.4 and 1.5 ATA. The cabin body is made of TPU material, weighs about 13 kg, and is about 220 cm long and 80 cm in diameter when unfolded; the widened horizontal cabin also covers these three pressure levels and increases in diameter to 90 cm. The inverted writing of hyperbaric chamber 1.5 ata, or hyperbaric oxygen chamber 1.5 ata with emphasis on oxygen supply, refers to the 1.5 ATA specification in this type of low-pressure software cabin.

On the hardware compartment side, 1.5 ATA is the starting point. The pressure specifications of the stainless steel-based rigid horizontal cabin usually start from 1.5 ATA and are more concentrated in 2.0 ATA; while the vertical and multi-person rigid cabin are basically designed according to 2.0 ATA. So it’s also 1.5 ATA. One may be a foldable soft cabin, and the other may be a fixed-mount stainless steel hardware cabin. The two are very different in structure, oxygen supply method and use. Because 1.5 ATA is this watershed, when choosing a model, you must first distinguish whether you are looking at software or hardware.

What to check when buying 1.5 ATA equipment

After locking the 1.5 ATA pressure, there are a few things to confirm item by item. To distinguish whether ATA is absolute pressure, psi is gauge pressure or absolute pressure, it is best to let the supplier give the full conversion. The complete parameters cannot be represented by just one 1.5 ATA figure either, and one device should also indicate the normal operating pressure, the maximum permissible operating pressure and the set pressure of the pressure relief device.

Higher pressure does not automatically mean better fit or safer. Target pressures must be assessed together with the intended use, structural design, oxygen supply method, operating instructions, and professional supervision requirements. The 1.5 ATA is still below the 2.0 ATA threshold required for clinical hyperbaric oxygen. Based on the pressure figures alone, neither software nor hardware can be used as a clinical treatment module; the US market can query the 510(k) records of specific devices by product code CBF, and note that 510(k) cleared and FDA approved are two different things.

Finally, back to the usage scenario. The soft 1.5 ATA cabin needs to be operated according to the specific model instructions, continuously monitored by qualified personnel, and equipped with fire protection and grounding measures in a high-concentration oxygen environment; the hard cabin needs to verify the installation conditions and professional management requirements. When you compare pressure, structure, use and compliance status, the 1.5 ATA specification is truly selected and understood.
