Hyperbaric Oxygen Therapy

Oxygen is critical to life.  Without oxygen, you die in a few minutes.  However, there are misconceptions about oxygen therapy.  In a normal situation, oxygen is carried by hemoglobin inside red blood cells and delivered to the tissues/cells.  If your lungs are working correctly, your hemoglobin will be about 95%-98% saturated.  This means that breathing a higher concentration of oxygen from a tank or other oxygen source does little to nothing because your hemoglobin can't carry any more oxygen!  The measurement device for this is called a PaO2 measurement.

The amount of oxygen that will dissolve in a liquid is dictated by the voltage of the liquid and the atmospheric pressure.  If one increases either, more oxygen will go into solution.  The liquid part of the blood is called the plasma.  Normally there is very little oxygen in the plasma.  Thus when you use hyperbaric oxygen to increase the atmospheric pressure, more oxygen will dissolve in the plasma.  This is the advantage of hyperbaric oxygen over just breathing oxygen at atmospheric pressure.  In addition to having more oxygen available to cells, oxygen in the plasma can get to areas where the red blood cells are too large to access.


Since it was develped to treat the bends suffered by divers surfacing too rapidly, it has been extensively studied for other illnesses.  A search for "hyperbaric oxygen" on PubMed gives 6581 published articles!


The research continues to outstrip FDA approval and standard-of-care medicine.  In spite of the research showing that increasing the availability of oxygen helps almost any chronic and most acute injuries, the FDA has only approved its use in the following since it costs millions of dollars for FDA approval for each use.  Since one cannot patent oxygen, there is very little incentive for anyone to spend the money to get it approved for other uses.
