Calculate how the composition of the alveolar air changes with calm breathing. |
|
Answer» Answer: ALVEOLAR AIR contains MUCH more water vapor (6.2 percent) and carbon dioxide (5.3 percent), resulting in a dilution of nitrogen to 74.9 percent and oxygen to 13.6 percent. Oxygen diffuses continuously from the alveolar air through the alveolo-capillary membrane into the blood. Alveolar minute ventilation is less than minute ventilation and is calculated as ([tidal volume − dead space] × respiratory rate) or ([500 mL − 150 mL] × 12 breaths/min) = 4200 mL/min.
