Question 2 of 5

Correct Answer: B
Rationale: The O2 content of whole blood is determined by the partial pressure of oxygen (PO2) and the oxygen saturation. The pulse oximeter does not measure the PO2. The pulse oximeter is a noninvasive method of measuring the arterial oxygen saturation. The PO2 is the amount of O2 dissolved in plasma, which the pulse oximeter does not measure. The affinity of hemoglobin for O2 is the relationship between oxygen saturation and PO2 and is not measured by the pulse oximeter.
