‼️👉 Step-by-Step: What Happens During a Hyperbaric Oxygen Therapy (HBOT) Session 👌⁉️
✅️ 1. Medical Assessment and Preparation
Before the first session, a medical consultation is conducted.
The healthcare provider checks for any contraindications, such as untreated pneumothorax, certain lung diseases, or ear and sinus infections.
Electronic devices, oil-based cosmetics, and flammable materials are generally not allowed inside the chamber.
✅️ 2. Entering the Chamber
The patient takes a position inside the chamber:
In a monoplace (single-person) chamber, the patient usually lies on a special bed or mattress.
In a multiplace (multi-person) chamber, the patient sits or lies down while oxygen is delivered through a mask or hood.
✅️ 3. Pressurization (Compression)
The operator gradually increases the pressure inside the chamber.
This process typically takes 10–15 minutes.
During this time, patients may experience a sensation of ear fullness similar to what is felt during airplane takeoff.
To equalize ear pressure, patients may:
- swallow,
- yawn,
- chew gum,
- move their jaw,
- perform the Valsalva maneuver (gently exhaling while pinching the nose and keeping the mouth closed).
✅️ 4. Treatment Phase
Once the target pressure is reached (typically between 1.3 and 2.0 ATA in wellness and regenerative applications, with higher pressures used for certain medical treatments), the therapy phase begins.
The patient breathes high-concentration oxygen, usually close to 100%, through an appropriately fitted oxygen mask or hood.
During the session, patients can typically:
- relax,
- listen to staff instructions,
- read a book or magazine,
- in some chambers, watch movies or listen to music.
✅️ 5. Depressurization
At the end of the session, the pressure is gradually reduced back to normal atmospheric pressure.
This process usually takes 5–10 minutes.
Patients may again experience pressure changes in their ears.
✅️ 6. Exiting the Chamber
Once the pressure has fully equalized, the chamber is opened.
Patients leave the chamber and can usually return to their normal daily activities unless otherwise advised by their healthcare provider.
Some individuals may experience temporary fatigue, drowsiness, or mild lightheadedness, but these effects generally resolve quickly.
‼️👉 How Long Does a Session Last ⁉️
A typical session lasts between 60 and 120 minutes.
Depending on the condition being treated, a treatment plan may include approximately 20–40 sessions or more.
‼️👉 What Happens in the Body 🤔⁉️
Under increased atmospheric pressure, the blood is able to dissolve and carry significantly more oxygen than under normal conditions. As a result, oxygen can reach tissues more effectively, including areas with reduced blood supply.
HBOT may:
- support wound healing,
- reduce swelling and inflammation,
- promote the formation of new blood vessels,
- stimulate the body's natural regenerative processes,
- support the mobilization and activity of progenitor cells and stem cells involved in tissue repair.
It is important to note that the benefits of HBOT are not solely related to increased stem cell activity. The primary effect of the therapy is enhanced oxygen delivery to tissues, which supports the body's natural healing and recovery mechanisms.
