Types Of Hyperbaric Oxygen Chamber

Hyperbaric Oxygen Therapy (HBOT) chambers are classified into monoplace (single-person, 100% oxygen), multiplace (multiple people, air-pressurized with oxygen masks), and mild/soft chambers (portable, low pressure). Understanding the differences between these types is essential for patients and medical providers to ensure the right therapeutic approach for specific health needs.

Single Hyperbaric Oxygen Chamber

This is the configuration I see most often in major wound care centers and hospitals.

Capacity and operation: Designed for a single person, patients are usually transported into the cabin while lying on a cart.

Environmental settings: The entire interior of the cabin is directly filled with 100% medical oxygen. This design is quite efficient, patients do not need to wear a mask or hood, directly breathe high concentrations of oxygen.

Application scenarios: Mainly used to treat chronic wounds, radiation injuries and specific infections.

Structural considerations: This type of cabin is mostly made of transparent acrylic, with a 360-degree view. From the perspective of clinical monitoring, this greatly reduces the patient’s claustrophobia, and it is also convenient for us to observe the signs in real time outside the cabin.

Multi-Person Hyperbaric Oxygen Chamber

If a hospital has a large number of outpatients or needs to deal with severe cases, the multi-person cabin is almost standard.

Capacity and environment: The cabin is spacious and can accommodate two people or even more than twelve people. Unlike the single cabin, the multiplayer cabin is filled with compressed air. In order to obtain a therapeutic effect, the patient must wear a face mask or a lightweight hood to inhale pure oxygen.

Clinical advantage: The core value of this cabin is “accessibility”. When dealing with critically ill patients, it is vital to have medical personnel directly into the cabin for real-time care.

Comfort: Large space means high freedom. For patients who need a long course of treatment, this environment is indeed much more humane than a single cabin.

Mild Hyperbaric Chambers (“Soft” Chambers)

In recent years, these soft cabins have been very popular in the health care circle, but everyone must understand that they are completely different from clinical-level equipment.

Material and portability: Made of flexible materials such as nylon and polyurethane, it is very convenient to install in non-clinical environments.

Physical pressure: Their pressure values are usually between 1.3 and 1.5 ATA, which is much lower than the hard cabin 1.5 to 3.0 ATA standard.

Oxygen supply: It is mostly filled with ordinary air (oxygen content is about 21%), rather than the 100 pure oxygen used clinically.

Advice for use: This is more like an auxiliary means for altitude sickness relief, athlete’s physical recovery or SPA conditioning.

On The Selection Logic Of “Hard Cabin” And “Soft Cabin”

When evaluating devices, I usually emphasize the bottom line of “medical effectiveness.”

Hard-shell cabin (single/multi-person): belongs to medical grade standard. For such emergencies as decompression sickness, carbon monoxide poisoning or severe wound repair, there is no hard cabin support with high pressure and pure oxygen, and the therapeutic effect is basically impossible.

Soft capsule: although it is easy to use, but its treatment range is too narrow. I must remind you that the soft chamber is absolutely not a substitute to treat those complex systemic diseases.

Finally, no matter type of cabin you choose, be sure to consult a medical professional before entering the cabin, and don’t neglect the matching degree between the treatment plan and your own health needs in order to save trouble. Safety and effectiveness are always the first principles of medical evaluation.
