Blood tests like the ABG or arterial blood gases test evaluate how much acid is in the blood and if that acid amount is out of balance as opposed the blood being more alkaline. The arterial blood gases test is one of the tests that is used for lung function capacity in instances like lung and respiratory disease. The ABG test is also used for people with cancer, heart disease and metabolic diseases or disorders. To prevent the effects of hypoxia in the body the body needs a proper pH balance so that either respiratory acidosis(when there is not enough oxygen in the body necessary for carbon dioxide removal) or respiratory alkalosis(hyperventilation that can interfere with the body's exchange of oxygen) does not occur. Metabolic problems occur such as kidney failure(when the blood is too acidic) from diabetes, heart and liver failure due to the increase of carbon dioxide in the body. This means that when the body does not get enough oxygen by respiratory function or when the lack of oxygen has an effect on the body by way of metabolic due to too much carbon dioxide or acid hypoxia can occur.
Oxygen is a necessity, but too much oxygen or receiving 100% oxygen for a prolonged period of time is not. Problems that occur with prolonged used of 100% oxygen can cause vasoconstriction in babies and acute lung injury and alveolar collapse in adults because of the production of hydrogen peroxide, superoxide ect. which are oxygen free radicals that are produced. The oxygen free radicals can damage enzymes, nucleic acids and membrane lipids.
Supplements including oxy-drops and that of low-deuterium water may help with illnesses and diseases that ultimately cause hypoxia and can be used when you certainly want to increase the flow of oxygen in the body without causing damage. When the glass is half full are you optimistic or pessimistic?
