A hospital hyperbaric chamber is a medical device that delivers pure oxygen in a controlled environment to help the body heal faster. It’s used to treat wounds, infections, and other oxygen-related conditions by increasing oxygen levels in the blood.
If you’ve ever wondered how hospitals utilize hyperbaric chambers and what makes them so effective, this guide explains their purpose, the treatment process, and the health benefits. It also shares insights into patient experiences, illustrating how HBOT can support recovery, wellness, and overall quality of life in medical settings.
Understanding What a Hospital Hyperbaric Chamber Does
A hospital hyperbaric chamber is a sealed room or tube where patients breathe 100% oxygen under higher-than-normal atmospheric pressure. This pressure allows oxygen to dissolve more effectively into blood plasma, enhancing tissue repair and reducing inflammation.
Why Hospitals Use Hyperbaric Oxygen Therapy (HBOT)
Hospitals use HBOT to treat various medical conditions, including:
-
Non-healing diabetic wounds
-
Carbon monoxide poisoning
-
Radiation tissue damage
-
Severe infections
-
Air or gas embolisms
Hyperbaric oxygen therapy is widely endorsed by medical organizations for its capacity to enhance oxygen delivery throughout the body, reduce inflammation and swelling, and stimulate angiogenesis. These effects collectively support tissue repair, accelerate healing, and improve overall recovery outcomes for patients with diverse medical and wellness needs.
Fun fact: Breathing oxygen in a pressurized environment can deliver 10–15 times more oxygen to tissues than normal air!
How a Hospital Hyperbaric Chamber Works Step-by-Step
During a hyperbaric oxygen therapy session, your body is exposed to pure oxygen at elevated pressures. This process increases oxygen absorption in the blood, promotes cellular repair, reduces inflammation, and supports tissue healing, giving the body an optimal environment for recovery and regeneration.

Step |
Description |
|
1. Preparation |
The patient lies down in the chamber, removing any flammable items. A technician ensures comfort and safety. |
|
2. Pressurization |
The chamber pressure gradually increases, simulating the feeling of descending underwater. |
|
3. Oxygen Therapy |
Once at target pressure, the patient breathes pure oxygen for 60–120 minutes. |
|
4. Decompression |
Pressure is slowly released to return to normal levels safely. |
The entire process is painless, though some patients feel mild ear popping (like during airplane takeoff).
Hospital vs. Home Hyperbaric Chambers: What’s the Difference?
While both hospital and home hyperbaric chambers deliver oxygen therapy, hospital chambers are built for medical-grade treatments under professional supervision. They offer higher pressure levels, precise monitoring, and advanced safety features, making them suitable for severe conditions, post-surgical recovery, or complex medical cases requiring controlled, clinical environments.

What Patients Feel During a Hospital Hyperbaric Session
Most patients describe their sessions as relaxing and even meditative. The chamber is transparent, allowing communication with medical staff. You can listen to music, watch TV, or simply rest.
Some mild sensations, like ear fullness, occur as pressure changes, but technicians help with equalization. Once the pressure stabilizes, breathing feels normal just with purer, more concentrated oxygen.
Benefits of a Hospital Hyperbaric Chamber
The primary goal of hyperbaric oxygen therapy is to increase oxygen delivery to the body’s cells, promoting faster healing. Enhanced oxygen flow supports tissue repair, reduces inflammation, aids in infection control, and boosts overall cellular function, helping the body recover more efficiently from injuries, chronic conditions, or post-surgical stress.
Key Benefits Include:
-
Faster wound healing after surgery or injury
-
Reduced swelling and inflammation
-
Improved circulation in damaged tissues
-
Enhanced immune response
-
Detoxification from carbon monoxide or gas poisoning
According to many hospital case studies, HBOT can reduce recovery time by up to 40% in certain wound-care patients.
