Cindy is taking 14 breaths per minute. Her vital capacity is 3000 mL, her total lung capacity is 4000 mL, and her tidal volume is 450 mL per breath. Calculate the following:
A. Cindy's total pulmonary ventilation (minute volume)
B. Cindy's alveolar ventilation rate
A. 14 breaths/min × 450 mL/breath = 6300 mL/min
B. Alveolar vent= 14 breaths/min × (450 mL/ breath - 150 mL dead space)
= 14 breaths/min × 300 mL/breath = 4200 mL/min
