What does a TcPO2 of above 40 mm Hg indicate?

Normal oxygen delivery to the skin
Impaired wound healing
Severe tissue hypoxia
Risk of infection

The correct answer is: Normal oxygen delivery to the skin

A TcPO2 (transcutaneous partial pressure of oxygen) level above 40 mm Hg indicates normal oxygen delivery to the skin. This measurement reflects the amount of oxygen that is available at the tissue level, which is essential for various cellular processes, including wound healing. In the context of wound care, adequate oxygen levels promote the necessary conditions for the healing process. When oxygen delivery is sufficient, tissues can perform their metabolic functions effectively, leading to the formation of new blood vessels, collagen synthesis, and overall tissue repair. Therefore, a TcPO2 level exceeding 40 mm Hg is considered a positive sign of adequate local oxygenation, which is crucial for healthy wound healing outcomes.
