A 39-year-old, 5'4", 138 lb female patient requires intubation and mechanical ventilation. Her body temperature is 39° C. She has no history of lung disease. The appropriate initial minute ven-tilation for this patient is which of the following?
a. 5.7 L/min
b. 6.8 L/min
c. 7.6 L/min
d. 13.8 L/min
ANS: B
First calculate ideal body weight (IBW) for a female, using the formula 105 + 5(ht – 60). This patient's IBW is 57 kg. Minute ventilation is about 100 mL/kg IBW, which would be 57,000 mL/min or 5.7 L/min. VE would have to be increased by 10% for each degree above 37° C: a to-tal increase of 20% of 5.7 = 1.14; therefore, the new minute ventilation (VE) would be 5.7 + 1.14 = 6.8 L/min.
