1. A device for the transcutaneous determination of blood gases comprising:

  • a transcutaneous sensor for the measurement of at least one of the parameters of skin carbon dioxide partial pressure (PsCO2) and skin oxygen partial pressure (PsO2), at least one sensor for the measurement of the tissue blood flow (F) local with respect to the transcutaneous sensor, and a device for the calculation of at least one of the parameters of transcutaneous carbon dioxide partial pressure (tcpCO2) and transcutaneous oxygen partial pressure (tcpO2) from the measured skin carbon dioxide partial pressure (PsCO2) or the measured skin oxygen partial pressure (PsO2) respectively, with a factor dependent on the local tissue blood flow (F) being taken into account in the calculation of at least one of the parameters of transcutaneous carbon dioxide partial pressure (tcpCO2) and transcutaneous oxygen partial pressure (tcpO2).
