WebThis is the static compliance measurement. Dynamic compliance is measured by dividing the tidal volume, the average volume of air in one breath cycle, by the difference between the pressure of the lungs at full inspiration and full expiration C D = V T /(P I-P E). Static compliance is always a higher value than dynamic.
