ReviewTranscutaneous measurement of partial pressure of oxygen and carbon dioxide.
Transcutaneous monitoring is noninvasive and relatively simple to use. In neonates and small infants, this monitoring technique may provide very useful clinical information. ⋯ Because transcutaneous gases depend on skin perfusion, however, it may be useful in monitoring tissue perfusion, especially in patients with peripheral vascular disease and tissue flaps. The heating of the monitoring probe necessitates frequent site changes to avoid thermal injury, which make it more labor intensive than other noninvasive monitoring methods.

Pulse oximetry is a reliable, noninvasive, easy to use means of continuously determining arterial oxygen saturation in virtually any setting. This article details the historical and technical development of this monitor; reviews the literature on application, accuracy, and response; and presents an overview of future advances.
