Question

Quizplus · Accepted Answer

The normal partial pressure of oxygen (PaO2) in arterial blood is between 80 to 100 torr, which is equivalent to 10.6-13.3 kPa. This range represents the optimal level of oxygenation to ensure adequate delivery of oxygen to the body's tissues. Other options are not within the normal range.
