Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen in a sealed chamber. This concentration is 5 times higher than the normal air we breathe. The chamber is also pressurized to create 1.5 to 3 times normal atmospheric pressure. These changes can improve blood circulation and the blood’s ability to deliver oxygen to the body.
Over a period of several minutes, the technician will slowly depressurize the chamber. You will likely have some ear popping and feel light-headed and tired. However, you should be able to go back to your daily activities. You may have more than one session over a period of several days.
