WebOct 22, 2024 · The average maximum capacity of a healthy lung is determined by a person’s height and varies. The average is approximately 6,100 milliliters (ml), which is equal to six liters, or approximately three large soda bottles’ worth of air. This benchmark can help healthcare providers determine if lung function is compromised. WebTotal Lung Capacity (TLC): The residual volume (air you cannot expire) + vital capacity (total volume available for use) = total lung capacity. In other words, TLC is the total volume of the lungs! Minimal Volume (MV): Should the volume of the lungs fall below this value, the lungs will collapse. Figure: Respiratory Volumes and Capacities
