A spontaneously breathing patient has a normal PaCO2 of 40 mm Hg, a minute ventilation (VE) of 6 L/min, and a VD/VT ratio of 35% (0.35). Then the patient develops a pulmonary embolus (PE), blocking blood flow to a significant number of ventilated avleoli. Consequently, the measured VD/VT increases to 65% (0.65). 1. Calculate the alveolar ventilation associated with teh original PaCO2 of 40 mm Hg. 2. To maintain the same PaCO2 of 40 after the embolus occurs, what change must occur in total minute ventilation (VE)?
