Why Do Transcutaneous Oxygen Tension (PO₂) and Carbon Dioxide Tension

question 1

Multiple Choice

Why do transcutaneous oxygen tension (PO₂) and carbon dioxide tension (PCO₂) values differ from PaO₂ and PaCO₂ measurements?

• A) Because of the lag time between the cardiac output and the time the blood reaches the transcutaneous electrode site
• B) Because the skin is much more permeable to oxygen than carbon dioxide
• C) Because oxygen is consumed and carbon dioxide is produced in transit from the left ventricle to the electrode site
• D) Because metabolism in the tissue consumes oxygen and produces carbon dioxide at the site of the electrode
