How is lung compliance expressed
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. Web27 dec. 2024 · Definition noun (1) The ability of the lungs to stretch in a change in pulmonary volume relative to an applied change in pressure. (2) A measure of the distensibility of lung using the following formula: C = ΔV / ΔP, where ΔV is the change in volume and ΔP is the change in pressure, typically expressed in L/cm HOH. …
