Ventilation rate is the volume of air moved into the lungs per minute.

1. Calculate tidal volume (dm³)
2. Calculate breathing rate (min⁻¹)
3. Calculate ventilation rate (dm³ min⁻¹) by multiplying tidal volume by breathing rate

Vital capacity is the maximum volume of air that can be inhaled and exhaled.

The tidal volume is the volume of air inhaled and exhaled in an average breath during rest.

The breathing rate is the number of breaths per minute.

The inspiratory reserve volume is the maximum volume of air that can be inhaled above a normal inhalation.

The expiratory reserve volume is the maximum volume of air that can be exhaled above a normal exhalation.

The residual volume is the volume of air that remains in the lungs after the largest possible exhalation.

The total lung capacity is the vital capacity added to the residual volume.
