Calculate the alveolar ventilation of a patient in the postanesthesia care unit, following general anesthesia, if the patient inhales 400 mL of air in each breath 10 times per minute.
A) 1.5 L/min
B) 2.0 L/min
C) 2.5 L/min
D) 3.0 L/min
C) 2.5 L/min
Explanation: A) First subtract the dead space: 400 mL - 150 mL = 250 mL. Then, multiply the volume by the breaths per minute: 250 mL * 10 breaths/minute = 2500 mL/min. Convert to L/min: 2.5 L/min.
B) First subtract the dead space: 400 mL - 150 mL = 250 mL. Then, multiply the volume by the breaths per minute: 250 mL * 10 breaths/minute = 2500 mL/min. Convert to L/min: 2.5 L/min
C) First subtract the dead space: 400 mL - 150 mL = 250 mL. Then, multiply the volume by the breaths per minute: 250 mL * 10 breaths/minute = 2500 mL/min. Convert to L/min: 2.5 L/min
D) First subtract the dead space: 400 mL - 150 mL = 250 mL. Then, multiply the volume by the breaths per minute: 250 mL * 10 breaths/minute = 2500 mL/min. Convert to L/min: 2.5 L/min
