What is the normal range for tcPO2?

Explanation:
TcPO2 reflects the amount of oxygen tension at the tissue level as measured through a warmed skin sensor. In healthy individuals with good peripheral perfusion, the transcutaneous reading tends to track arterial oxygen tension and typically sits in the 60–80 mmHg range. This window indicates adequate tissue oxygen delivery. Readings much lower—around or below 40 mmHg—suggest tissue hypoxia and potential perfusion issues, while readings higher than about 80 mmHg are less common in normal conditions and may reflect measurement factors or very high inspired oxygen.
