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....

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.
