Which condition would result in the highest alveolar ventilation rate?
A) quiet breathing.
B) a normal respiratory rate and normal tidal volume.
C) a normal respiratory rate and high tidal volume.
D) a high respiratory rate and very low tidal volume.
E) a low respiratory rate and very low tidal volume.

Question

Quizplus · Accepted Answer

Alveolar ventilation rate is the amount of air that reaches the alveoli per minute. It is calculated by multiplying the respiratory rate by the tidal volume and subtracting the dead space volume. Among the given choices, a normal respiratory rate and high tidal volume (option C) would result in the highest alveolar ventilation rate as it would allow a greater amount of air to reach the alveoli per minute. Option D has a high respiratory rate but very low tidal volume, which would result in less air reaching the alveoli per minute. Option B has a normal respiratory rate and normal tidal volume, which would result in a lower alveolar ventilation rate compared to option C. Options A and E do not provide sufficient information about the respiratory rate and tidal volume to determine the alveolar ventilation rate.
