The possibility of continuously monitoring arterial blood oxygen and carbon dioxide using heated surface electrodes on human skin was discovered in the early 1970s and made commercially available by 1976.  These devices were applied initially to premature infants in an effort to reduce the incidence of blindness due...

Transcutaneous oxygen measurements play an important role in the evaluation and management of problem wounds. No precise threshold or target values exist for the prediction of outcome, and it is quite possible that each wound will have highly individualized oxygen dose requirements. Correction of ambient dermal oxygen ...

This lab study shows that transcutaneous values can closely follow changes in arterial blood gas by using an electrode temperature of 45 °C to monitor exercise with gradual workload.

There are several diagnostic approaches to identify and quantify different types of vascular disease. However, these methods usually do not reflect the condition of the cutaneous circulation.  Because transcutaneous oxygen reveals the status of cutaneous circulation, it has been shown to be a powerful diagnostic tool ...

Transcutaneous monitoring of carbon dioxide plays an important role during short-term and long-term treatments for ventilatory failure. Progress during short-term treatments can be judged through tcpCO₂ recordings - especially to avoid crash reintubation of patients who have been weaned off invasive ventilation....
