WebLung compliance is the change in lung volume per unit change in pressure. What is the mathematical formula for compliance? Compliance= change in volume / change in pressure Lung volume depends on body size. Therefore, absolute values of compliance cannot be used to compare lung compliances of different sized individuals. WebLung compliance is a description of how easy the lung is to inflate, more specifically, how much volume will change for a given pressure differential. Figure 3.3 shows a typical and normal lung compliance curve.
