Method For Measuring The Transcutaneous Co2 Partial Pressure On An Ear Lobe

摘要

In a process for measuring partial transcutaneous CO₂ pressure on an earlobe 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 contact with the earlobe, the sensor contact surface is heated. During a first phase, the sensor contact surface is kept at an elevated temperature of at least 41.5° C. in order to prevent the measured value of partial transcutaneous CO₂ pressure from exceeding, due to the measurement process itself, the partial transcutaneous CO₂ pressure achieved after stabilization. The temperature of the sensor contact surface is then reduced to between 37° C. and 41° C. This facilitates considerably faster evaluation of the measured values.
