Question

What is the alveolar minute volume of a patient with a respiratory rate of 12 breaths/min, a tidal volume of 450 mL, and a dead space volume of 135 mL?

A) 3,650 mL
B) 3,780 mL
C) 4,260 mL
D) 5,400 mL

Answer 1

The alveolar minute volume of a patient can be calculated by multiplying the respiratory rate by the tidal volume. In this case, the alveolar minute volume is 5,400 mL/min.

Step-by-step explanation:

The alveolar minute volume can be calculated by multiplying the respiratory rate by the tidal volume. In this case, the respiratory rate is 12 breaths per minute and the tidal volume is 450 mL. Thus, the alveolar minute volume is calculated as 12 breaths/min × 450 mL/breath = 5,400 mL/min.
