DEVICE FOR THE COMBINED MEASUREMENT OF THE ARTERIAL OXYGEN SATURATION AND THE TRANSCUTANEOUS CO2 PARTIAL PRESSURE OF AN EAR LOBE

摘要

A device for the combined measurement of the arterial oxygen saturation and the transcutaneous CO2 partial pressure or an ear lobe, has a sensor which performs pulse oximetric measurement of the arterial oxygen saturation, measurement of the transcutaneous CO2 partial pressure, and warming of a sensor contact surface intended for contact with the ear lobe. For pulse oximetric measurement of the arterial oxygen saturation at least two LEDs and one photodiode are arranged so that when the device is attached to an ear lobe they are located on the same side of the ear lobe.
