Transcutaneous oximetry (TcPO2) is a painless, non-invasive test that directly measures the oxygen level of tissue beneath the skin (partial pressure of oxygen). Because oxygen is carried to tissues by blood flow in the arteries, TcPO2 is an indirect measure of blood flow.


This test is often used to evaluate advanced peripheral arterial disease, a condition in which blood flow to an extremity (usually the leg) is greatly reduced.


Results of this test help physicians determine how severely tissues are deprived of blood flow. The test is often especially useful in predicting wound healing, amputation healing, or identify individuals who may benefit from bypass surgery and hyperbaric oxygen therapy.
