50 cc tidal volume (awfully little!) x 12 breaths/minute is 600 cc per minute, or 0.6 l.
50 cc tidal volume x 20 breaths/minute = 1000 cc per minute, or 1 l.

tidal volume x breathing rate
Pulmonary Ventilation = Tidal volume X ventilation rate Simply rearrange the equation to find tidal volume Tidal volume = Pulmonary ventilation / ventilation rate Pulmonary ventilation is the volume of air moved into the lungs in one minute Tidal volume is the volume of air breathed in in one breath whilst at rest Ventilation rate is the number of breaths taken in one minute
Pulmonary ventilation is 6 liters/minute in resting individual. You have a respiratory rate of 12/minute and tidal volume of 500 ml/minute. During heavy exercise tidal volume increases from 10 % of vital capacity to about 50 % of vital capacity. And respiratory rate increases from 12 to about 40 to 45/ minute. Thus increasing the pulmonary ventilation to about 100 liter/minute.
the amount of air breathed in 1 minute. Minute Ventilation = Tidal Volume x Respiratory Rate
Tidal Volume x Respiratory Rate
Minute Venitlation is easiest calculated by multiplying the tidal volume (Vt) X Rate
The average adult at rest inhales and exhales something like 7 or 8 liters (about one-fourth of a cubic foot) of air per minute. That totals something like 11,000 liters of air (388 cubic feet) in a day.
Inspiratory reserve volume is the volume you can inhale past the normal tidal volume.
7.7 breaths per minute
The amount, called tidal volume, is basally about half a litre/500ml. But it, multiplies upon exertion.
Tidal volume increased.
