Calculate the alveolar ventilation for a person with a tidal volume of 600 ml, a dead space volume of 150 ml, and a respiratory rate of 15 breaths per minute.

Explanation

Alveolar ventilation is determined by subtracting the dead space volume from the tidal volume and then multiplying by the respiratory rate. Here, (600 ml - 150 ml) × 15 breaths/min = 450 ml × 15 = 6750 ml/min or 6.75 liters per minute.
