TCOMs as a screening tool for hyperbaric oxygen therapy.

Transcutaneous oximetry (TcPO2), often referred to as TCOM, is a noninvasive measurement of oxygen tension in the tissue via a heated electrode. TCOMs can be used prior to beginning hyperbaric oxygen (HBO) treatment to determine if the patient has adequate blood flow to the wounded area to benefit from HBO. A case study of how it can be used in a problematic wound is presented.
