What to Expect During a Hyperbaric Session
Follow a home or professionally operated hyperbaric session from preparation and ear equalization to time at pressure and safe exit.
A session has four stages: preparation, gradual pressurization, time at the selected pressure and controlled depressurization. The exact equipment, supervision and timing differ between a home wellness setup and a professionally operated facility.
Before You Start
Wear clean, comfortable clothing and remove any item prohibited by the chamber manual or facility operator. Do not assume phones, tablets, battery devices, lighters, vaping products, oils or alcohol-based products are permitted. Check the chamber, hoses, oxygen unit and seals before entry; soft chambers such as the COSL15 use a triple-zip entry.
- Confirm the selected pressure and expected session time
- Keep flames, smoking and heat-producing items away from the chamber and oxygen equipment
- Use only clothing, personal products and entertainment items permitted for that model
- Know how to communicate, slow pressurization and release pressure before the session starts
Entering and Pressurizing
The chamber gradually pressurizes to your chosen level. The sensation is similar to the descent of an aircraft: you feel a gentle change in your ears, which clears with simple equalization — swallowing, yawning or a soft pinch-and-blow. Pressurization takes a few minutes and is intentionally slow and comfortable.
Breathing and Relaxing
At pressure, the specified oxygen system delivers oxygen through a mask or headset. Home and wellness routines commonly plan 60–90 minutes at pressure; professionally directed protocols can use different session lengths and schedules. Use only approved activities inside the chamber. A spacious sitting model like the COSE15 provides room to sit upright or recline.
- Home and wellness sessions commonly plan 60–90 minutes at pressure
- Professional protocols may use different timing and supervision
- Soft chambers let you sit, recline or lie flat
- Hard-shell chambers add climate control and a two-way intercom
Depressurizing and Exiting
At the end, the chamber returns to normal atmospheric pressure in a controlled way. Keep equalizing as needed and wait until pressure is fully released before opening the door or zipper. Stop the session and contact the operator or support team if you develop chest discomfort, breathing difficulty, severe ear pain, confusion or another unexpected symptom.
Getting the Most from Sessions
Like most wellness routines, consistency matters more than any single session. To set up a comfortable routine at home, see mild hyperbaric therapy at home, and if you are choosing your first chamber, the COSL15 and COSE15 are easy, comfortable starting points.
