The volume of air inspired into or expired out of the lungs in 1 min. It usually refers to the expired amount and can be calculated using the following equation: VE = VT × f, where VE represents the minute ventilation in litres (l−1) per minute, VT represents tidal volume in litres, and f represents respiratory frequency in breaths per minute. A typical resting value of minute ventilation is 6 l min−1, but it may rise to as much as 180 l min−1 during intense exercise. The change in minute ventilation has been used to identify the anaerobic threshold (see minute ventilation method).
