Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized environment. Hyperbaric oxygen therapy is a well-established treatment for decompression sickness, but has also been found to benefit many other health concerns and issues.

​

In a hyperbaric oxygen therapy chamber, the air pressure is increased 2 to 3 times higher than normal air pressure. Under these conditions, your lungs can gather much more oxygen than would be possible breathing pure oxygen at normal air pressure.

This extra oxygen helps fight bacteria. It also triggers the release of substances called growth factors and stem cells, which promote healing.
