What is the normal minute ventilation (VE) in L/min?

The normal minute ventilation (VE) is typically recognized to be in the range of 5 to 6 liters per minute. Minute ventilation is calculated by multiplying the tidal volume (the amount of air moved per breath) by the respiratory rate (the number of breaths taken per minute). For a healthy adult at rest, the average tidal volume is about 500 mL, and at a respiratory rate of approximately 12 breaths per minute, this results in a minute ventilation of around 6 L/min.

This range is pivotal for understanding pulmonary function and assessing respiratory health. Values significantly below or above this range may indicate potential respiratory issues or abnormalities in breathing patterns due to illness or external factors. Understanding minute ventilation is crucial for ventilatory support and the management of patients in various clinical settings.
