Which of the following values is considered a normal TcpO2 reading?

  1. 15 mmHg

  2. 35 mmHg

  3. 45 mmHg

  4. 53 mmHg

The correct answer is: 53 mmHg

A TcpO2 reading reflects the partial pressure of oxygen at the skin's surface, providing insight into tissue oxygenation. Normal TcpO2 values range typically between 40 to 70 mmHg, indicating adequate oxygen delivery to tissues. The choice of 53 mmHg falls within this normative range, suggesting that, at this level, the tissues are likely receiving sufficient oxygen to meet their metabolic needs. Reading values lower than this, such as 15 mmHg, 35 mmHg, or 45 mmHg, may indicate inadequate oxygenation, which could point toward underlying issues that might require further assessment or intervention in a hyperbaric context. Thus, the selection of 53 mmHg as a normal TcpO2 reading accurately reflects the expected physiological conditions necessary for optimal tissue oxygenation.
