Respiratory minute volume (minute ventilation) is the volume of air inhaled or exhaled from a person's lungs per minute. In a healthy human in normal conditions, it averages about

In normal conditions, a healthy man can inspire or expire approximately 6000 to 8000 mL of air per minute.

Tidal volume is the volume of air inspired or expired during a normal respiration. It is approx. 500 mL.

On an average, a healthy human breathes 12-16 times/minute.

Minute ventilation = Tidal volume x Breathing rate

= 500 mL x 12-16 = 6000 to 8000 mL per minute = 6 to 8 litres per minute (average 7 litres)
