Oxygen is essential for cell metabolism, and in turn, tissue oxygenation is essential for all normal physiological functions. High blood and tissue levels of oxygen can be helpful or damaging, depending on circumstances and oxygen therapy should be used to benefit the patient by increasing the supply of oxygen to the lungs and thereby increasing the availability of oxygen to the body tissues. For personal use, high concentration oxygen is used as home therapy to abort cluster headache attacks, due to its vaso-constrictive effects. en.wikipedia.org/wiki/Oxygen_therapy
