Following data was obtained from a 20 year old medical student: tidal volume = 540 mL, paial pressures of CO2 in expired air & aerial blood ~ PECO2 = 20 mm Hg, PACO2 = 30 mm Hg: respiratory rate = 15/min. The alveolar ventilation would be:-
Alveolar ventilation = (tidal volume - dead space volume) x Respiratory rate= (540 - 180) 115 = 5.4 L/min
4.2 L/min
4.8 L/min
5.2 L/min
5.4 L/min
