transcutaneous oxygen/carbon dioxide monitoring

a method of measuring the oxygen or carbon dioxide in the blood by attaching electrodes to the skin. Oxygen is commonly measured through an oximeter, which contains heating coils to raise the skin temperature and increase blood flow at the surface. Oxygen content is calculated in terms of light absorption at various wavelengths. Transcutaneous carbon dioxide electrodes are similar to blood gas electrodes, with a Teflon membrane tip that is permeable to gases.
