A TcpO2 reading of 23 mmHg on the oor is considered what?

1. Normal

2. Hypoxic

3. Hyperoxic

4. Moderately hypoxic

The correct answer is: Hypoxic

A TcpO2 (transcutaneous partial pressure of oxygen) reading of 23 mmHg on the floor indicates a state of hypoxia, as normal TcpO2 values generally range from 50 to 70 mmHg in healthy individuals. In clinical practice, levels below 30 mmHg are typically interpreted as hypoxic, which characterizes inadequate levels of oxygen available to tissues. This becomes critical because when oxygen delivery is compromised, it can lead to various physiological disturbances and requires immediate attention and intervention to address the oxygen deficit. In the context of the options provided, the reading accurately reflects a hypoxic state, making it essential for healthcare professionals to monitor and potentially take action to improve patient oxygenation.
