A Typical Respiratory Minute Volume Is

Question

A typical respiratory minute volume is
A) 1 liter.
B) 2 liters.
C) 500 mL.
D) 6 liters.
E) 10 liters.

Accepted Answer

A typical respiratory minute volume is the amount of air inhaled and exhaled in one minute. The average respiratory rate for an adult is about 12-20 breaths per minute and the average tidal volume (amount of air inhaled and exhaled with each breath) is about 500 mL. Therefore, the typical respiratory minute volume is about 6 liters (12-20 breaths/min x 500 mL/breath = 6000-10000 mL/min = 6-10 L/min).
