What would the minute alveolar ventilation equal if a 6 ft tall,170 lb male has a VT of 550 mL and a respiratory rate of 11 breaths/min?
A) (550-170) x 11 = 4.18 L
B) (550 + 170) x 11 = 7.9 L
C) 550 + (170 x 11) = 1.87 L
D) 550 - (170/2.2) x 11= 4.65 L

Minute alveolar ventilation is calculated by subtracting dead space volume from tidal volume and then multiplying by the respiratory rate. The dead space is approximately 1 mL per pound of body weight, so for a 170 lb male, it is 170 mL. Thus, (550-170) x 11 = 4.18 L.
