HybO2 chambers

Hyperbaric chambers at the HybO2 House clinic are of the very highest quality and are among the best in the world.

To optimise effectiveness, pressure in a hyperbaric chamber should be greater than or equal to 1.5 ATA (Atmosphere Absolute). Normal atmospheric pressure when you are at sea level is 1 ATA. In clinical practice, pressures applied usually range from 2 to 3 ATA.

All HybO2 hyperbaric chambers at our clinic apply a minimum pressure of 2 ATA.

If you are interested in purchasing a hyperbaric oxygen therapy chamber, HybO2 offers a wide selection of chambers for sale including portable chambers suitable for use at home. Our team offers a bespoke consultation service to ensure that every client’s specific requirements are met. Find out more here.

  • I am a rugby player in the UK and have been using hyperbaric oxygen therapy to aid my body's recovery after matches. I can honestly say that I have never felt better and my energy levels have increased hugely.

  • Following my HBOT treatment, I've had a brilliant day. My breathing is almost back to normal, I've felt incredibly energised, and I have been able to complete everyday household tasks at a normal pace. Hyperbaric medicine is life changing. And I plan to continue using it after my Long Covid recovery. I'm a lot more optimistic now about returning to full health.
