How Does Hyperbaric Oxygen Therapy Work?

Normally, our atmospheric pressure at sea level, exerts 14.7 pounds per square inch of pressure over a given surface. This is equivalent to one atmosphere absolute (one ATA). In this atmosphere, we breathe approximately 20 percent oxygen and 80 percent nitrogen. During hyperbaric oxygen therapy (HBOT), the pressure is increased two or three times more than normal and you breathe 100 percent oxygen. Most patients are treated at two times the normal atmospheric pressure (two ATA).

The combination of high concentrations of oxygen (100 percent) and increased pressure cause large amounts of oxygen to be dissolved in your blood and other tissue fluids. There can be as much as 10 to 15 times the usual amount of oxygen dissolved in your blood, which gets more oxygen to the rest of your body.

Many different problems have been shown to benefit from hyperbaric oxygen therapy. Some of the common problems are:

  • Non-healing wounds (especially in diabetics)
  • Osteomyelitis (bone infections)
  • Radiation soft tissue damage including bladder, head and neck areas
  • Traumatic injuries including ischemia
  • Crushing injuries
  • Acute arterial insufficiency
