Device for the combined measurement of the arterial oxygen saturation and the transcutaneous CO2 partial pressure on an ear lobe

摘要

A device for the combined measurement of the arterial oxygen saturation and the transcutaneous CO₂ partial pressure on an ear lobe comprises a sensor. The sensor has means for pulse oximetric measurement of the arterial oxygen saturation, means for measurement of the transcutaneous CO₂ partial pressure and means for warming a sensor contact surface intended for contact with the ear lobe. The device makes simple and reliable measurement of the arterial oxygen saturation and the transcutaneous CO₂ partial pressure possible on an ear lobe.
