Transcutaneous Oxygen Measurement (TCOM or TcPO2)
This noninvasive test of the extremity measures tissue oxygen pressures in different conditions (Room air, supplemental oxygen, and extremity elevation). It assesses if ischemia will hinder healing, so further vascular evaluation can be done. TCOMs predict the likelihood of healing certain amputation levels so that the most distal amputation can be planned. The results may be used to gauge how responsive tissue is to Hyperbaric Oxygen therapy.
