Why a rigid steel chamber beats an inflatable one.
Soft (inflatable) HBOT chambers look cheaper on paper. When you run a clinic, the rigid design wins on pressure control, safety, noise and patient experience.
Pressure is where the difference lives
A soft tent tops out at around 1.3 ATA and wobbles under load. The OZ-150 delivers a stable 1.5 ATA with a digital controller that holds pressure within ±2 kPa across a 90-minute session. That matters because the therapeutic dose is pressure-time-oxygen — a chamber that drifts low is a chamber that under-treats.
Breathable, quiet, temperature-controlled
Patients sit upright on a built-in sofa inside the OZ-150. Internal air conditioning keeps the cabin at a comfortable 22–24°C even in summer, and HEPA-filtered fresh air means the session never feels stuffy. Compressor noise at the cabin stays below 65 dB — a conversation level.
Safety engineered in, not added on
- Pressure relief valve opens automatically above the rated pressure.
- Manual emergency vent lets staff depressurize the cabin in seconds.
- Audible and visible alarms trigger on over-pressure, power loss or O2 deviation.
- Continuous oxygen monitoring inside the cabin keeps O2 fraction below fire-safety limits.
- Tempered-glass observation window means staff never lose sight of the patient.
How a session runs
- Staff select the protocol on the touchscreen (pressure, duration, O2 flow).
- Patient seats inside, door closed, double-seal lock.
- Chamber pressurizes smoothly over 5–8 minutes to target pressure.
- Patient breathes 90–96% medical oxygen via mask or hood for the treatment phase.
- Gradual decompression over 5 minutes at the end.
Every step is logged on the controller, and a session report can be exported for the patient file.
