HBOT is a pressurized environment with high concentrations of oxygen.

HBOT has been very successful for some individuals with Chronic Lyme.   

Lyme and co-factors are anaerobic like most bacteria.  Anaerobic means it does not like oxygen.  Therefore, HBOT provides the optimal oxygen-rich environment to kill the Lyme bacteria. In addition to killing the Lyme bacteria, it also aids in reducing symptoms from Chronic Lyme. The high dose of oxygen treatment may reduce joint and muscle pain, and chronic inflammation.
