The respiratory rate times the tidal volume corrected for dead space is the
A) vital capacity.
B) respiratory minute volume.
C) pulmonary ventilation rate.
D) alveolar ventilation rate.
E) external respiration rate.

Question

Quizplus · Accepted Answer

The calculation of respiratory rate times tidal volume corrected for dead space gives the alveolar ventilation rate, which is the volume of air that reaches the alveoli per minute. Option A is incorrect as vital capacity is the maximum amount of air that can be forcefully exhaled after a maximal inspiration. Option B is incorrect as respiratory minute volume is the total volume of air moved in and out of the lungs per minute. Option C is incorrect as pulmonary ventilation rate is the total volume of air moved in and out of the lungs per minute but does not take into account the volume of air that does not reach the alveoli (dead space). Option E is incorrect as external respiration rate does not exist as a specific term in respiratory physiology.
