,9.1 L/min
Total minute ventilation = VT(RR)
.650(14)=9.1 Correct Answer ✓✓ If a patient had a tidal volume of 650
mL, respiratory rate of 14 breaths per minute, a physiologic dead space
of 175 mL, an FiO2 of 65, RQ equals 0.8, PaCO2 equals 30 mmHg, PB
equals 735 mmHg, what is the Patients actual total minute ventilation
(Ve) in question?
6.7 L/min
Note:
Actual minute alveolar ventilation VA = VT - dead space (RR)
650-175 = 475(14) = 6.65 we then round Correct Answer ✓✓ If a
patient had a tidal volume of 650 mL, respiratory rate of 14 breaths per
