Quizplus · Accepted Answer

The heating element of the transcutaneous CO₂ monitor and thermocouple maintain skin temperatures at 44°C.The increased temperature arterializes the vascular bed under the electrode,increasing circulation to that area.The PO₂ electrode's heating element also arterializes the sample site by increasing the skin temperature to 44°C.Oxygen diffuses through the skin and is measured by the electrode.
