Transcutaneous Oxygen Monitor is the device used for transcutaneous oximetry (TcPO2 or TCOM), which is a local, non-invasive measurement reflecting the amount of O2 that has diffused from the capillaries through the epidermis. This measurement provides information regarding the supply and delivery of oxygen to the underlying micro vascular circulation. It can be used for adults in wound evaluation, hyperbaric therapy, plastic surgery, amputation level determination, and peripheral vascular disease assessment, including the status of limb revascularization procedures
