MV = TV x RR
Average TV is 500ml
Average RR is 16
Thus average MV = 8000ml/min
Tidal Volume x Respiratory Rate
Minute Venitlation is easiest calculated by multiplying the tidal volume (Vt) X Rate
Minute volume is calculated by multiplying tidal volume by breath rate. Tidal volume is the amount of air inhaled or exhaled in one breath, while breath rate is the number of breaths taken per minute. By multiplying tidal volume and breath rate, you can determine the amount of air exchanged in one minute.

The minute volume is calculated by multiplying the respiratory rate by the tidal volume. In this case, with a respiratory rate of 20 breaths per minute and a tidal volume of 200 ml, the minute volume would be 20 x 200 ml, which equals 4000 ml, or 4 liters.
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.
The two factors used to calculate ventilation rate are tidal volume (the amount of air moved in and out of the lungs in one breath) and respiratory rate (the number of breaths taken per minute). These two factors together determine the amount of air exchanged in the lungs per minute.
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
the dead space must also be factored in, so the equation would be: RR(tidal volume-dead space)
