Web22 nov. 2024 · Exercise 4: Measuring Lung Volumes and Capacities. Human lung size is determined by genetics, gender, and height. At maximal capacity, an average lung can hold almost six liters of air, but lungs do not usually operate at maximal capacity. The air in the lungs is measured in terms of volumes and capacities. WebMinute ventilation (denoted as Ve) is the volume of air exchanged in the lung within a minute. This is analogous to cardiac output, the volume of blood pumped by the heart in a minute. As such, minute ventilation is the average tidal volume (V T) multiplied by the number of breaths taken in a minute (RR). Equation 3.1.
