This test determines the amount of oxygen and carbon dioxide dissolved in the blood, as well as the acid/base status. Oxygen and carbon dioxide levels are indicators of lung function. The acid/base status provides information on how well the lungs and kidneys are functioning. It can also give information as to whether there is a problem in the body, like an infection, that is throwing off the acid/base balance in the body.
If you are undergoing oxygen therapy, this test can help to see if the therapy is effective.
