The value of RQ can vary depending upon the type of diet and metabolic state of the person. A standard value of 0.82 for the typical human diet. At sea level without supplemented inspired oxygenation, the alveolar oxygen partial pressure (PAO2) is: PAO2 = (760 - 47) 0.21 - 40 / 0.8 = 99.7 mm Hg.

Explanation:

A-a oxygen gradient = PAO2 - PaO2
