If tidal volume is 500 mL and respiratory rate is 12 breaths per minute, what is the minute volume?

Explanation:
Minute volume (minute ventilation) is the total air moved in and out of the lungs each minute. It’s found by multiplying the air moved per breath (tidal volume) by the number of breaths per minute (respiratory rate). With a tidal volume of 500 mL and a respiratory rate of 12 breaths per minute, the calculation is 500 mL × 12 = 6000 mL per minute, or 6 L/min. This value reflects how much air is ventilating the lungs each minute.
