PROCESS FOR MEASURING PARTIAL TRANSCUTANEOUS CO2 PRESSURE AT AN EAR LOBE

摘要

In a process for measuring partial transcutaneous CO2 pressure at a ear lobe by means of a sensor having a measuring device for measuring the partial transcutaneous CO2 pressure and a heating system for heating a sensor contact surface for contacting the ear lobe, the sensor contact surface is heated. During a first phase, the sensor contact surface is held at an increased temperature of at least 41.5 °C in order to prevent the measured value of partial transcutaneous CO2 pressure from exceeding, owing to the measurement process itself, the partial transcutaneous CO2 pressure achieved after stabilisation. The temperature of the sensor contact surface is then lowered to 37 °C to 41 °C. The measured values can thus be evaluated considerably faster.
