What Happens During an O2 Box Session?

Step Inside a Session
For many first-time users, the biggest question is simply: “What actually happens in there?” Mild hyperbaric oxygen therapy sounds technical, but the experience itself is calm, comfortable, and surprisingly simple.

 Here’s a step-by-step look at a typical O2 Box session.

1. Check-In and Basic Screening

 Before a session, staff will typically:

• Review your intake form or basic wellness questionnaire

• Confirm any relevant health information and answer questions

• Explain what to expect during pressurization and decompression

 This is also a great time for users to decide how they want to spend their session—reading, working, listening to music, or just resting.

2. Getting Comfortable Inside the Chamber
O2 Box chambers are designed to feel like a small room, not a capsule. Users can walk in through an upright entry door and sit on comfortable seating.

 Inside the chamber, many people:

• Bring a book, tablet, or laptop

• Use headphones to listen to music or a podcast

• Close their eyes and treat it as a mini “reset” or meditation break

 Because the system is built from galvanized steel and engineered for stability, sessions are quiet with a consistent internal environment.

3. Pressurization: Reaching 1.3 ATA
Once everyone is seated, the operator begins pressurizing the chamber. Over several minutes, the pressure inside rises to 1.3 ATA—a mild increase that gently supports oxygen absorption without the intensity of deep-dive or hospital-grade chambers.

 Some people notice a sensation in their ears similar to ascending or descending in an airplane. Simple techniques like swallowing or yawning usually help equalize pressure.

4. Relax, Recover, or Focus
The majority of the session is simply time spent at pressure. Depending on the setup, users may breathe:

• Ambient air

• Oxygen via a nasal cannula

• Oxygen via a comfortable mask

 Throughout this time, clients often:

• Catch up on emails or planning

• Read or journal

• Meditate or nap

 Sessions typically last around 60 minutes, but providers can adjust length based on their specific programs.

5. Decompression and Exit
At the end of the session, the operator slowly brings the chamber back to normal atmospheric pressure. This step usually takes just a few minutes.

 Once decompression is complete, the door opens and users can exit, often describing the experience as:

• “Deeply relaxing”

• “Like a focused, quiet break in my day”

• “An easy add-on after a workout or appointment”

 There’s no downtime or required recovery period, so clients can typically go straight to their next activity.
