It is more efficient to increase alveolar ventilation by increasing tidal volume than by increasing respiration rate.

Question

Quizplus · Accepted Answer

Increasing tidal volume is more efficient for enhancing alveolar ventilation because it reduces the proportion of each breath that is spent on dead space ventilation (air that does not reach the alveoli for gas exchange), thus more of the inhaled air participates in gas exchange. Increasing the respiration rate without increasing tidal volume raises the proportion of each breath that is dead space, making it less efficient for gas exchange.
