Dimensions & space
Plan your space
A two-person chamber needs a dedicated room with clear access. Plan floor space for two occupants, the system unit beside the chamber and clear access to the door.
| Component | Size | Weight |
|---|---|---|
| Chamber | 82.7 × 41.3 × 70.9 in (2100 × 1050 × 1800 mm) | Approx. 1,653 lb (750 kg) |
Size and weight confirmed by OxyCheny in October 2026. The exact shipping weight is confirmed when your order is placed.
- Measure doorways, hallways and turns on the way to the room. The chamber is 41.3 in wide.
- Ask your contractor to confirm the floor can carry about 1,653 lb plus two occupants.
- Plan an outlet location for the system unit.

Safety & use
Before your first session
From OxyCheny's operating guidelines. This is general product guidance, not medical advice. Hyperbaric sessions aren't right for everyone, so check with your clinician before you begin.
Before you enter
- No phones, tablets, batteries or other electronics
- No lighters, matches, perfumes or other flammable items
- No sharp objects. Wear 100% cotton clothing.
During a session
- You may feel pressure in your ears during the first 10–15 minutes. Swallow or yawn to equalize.
- The system holds a steady pressure automatically
- At the end, it depressurizes slowly before the door opens. Never force the handle.
Care
- Daily: wipe the interior with a non-alcohol disinfectant and check the door seal
- Weekly: check the concentrator filters and clean the air intake
- Monthly: check the tubing and pressure relief valves. Replace the HEPA filters every 500 hours.
Pressure and oxygen can cause ear or sinus discomfort and other effects, and oxygen raises fire risk. Read the FDA's guidance on the safe use of hyperbaric devices.
Research
What the research explores
Most published trials used 2.0 ATA with 100% oxygen across 40–60 supervised sessions. Home chambers and protocols differ, so these findings don't automatically apply to home use.
Staying sharp with age
A randomized trial in adults over 64 reported improvements in attention and processing speed after a 60-session course. Read the study
Stamina and exercise capacity
Small controlled studies in older adults and in trained athletes aged 40–50 reported better aerobic measures under clinical protocols. Older adults · Athletes
Recovery between workouts
A small cyclist study at 1.3 ATA reported better performance in a follow-up effort. Overall, recovery research is mixed. Read the study
