In an adult, tidal volume measures 500 mL/breath, anatomic dead space is 120 mL/breath, and respiratory rate is about 10 breaths/min. What is the alveolar ventilation?

Question

Quizplus · Accepted Answer

Alveolar ventilation is calculated by subtracting the anatomic dead space from the tidal volume and then multiplying by the respiratory rate. So, (500 mL - 120 mL) * 10 breaths/min = 380 mL/breath * 10 breaths/min = 3.8 L/min.
