the value obtained when compliance is measured at true equilibrium, that is, in the absence of any motion.
stat·ic com·pli·ance(stat'ik kŏm-plī'ăns)
1. The ratio of the change in volume of a distensible vessel to the change in distending pressure when the pressure change is measured between points in time when the system is at rest.
2. The slope of the statically determined pressure-volume curve.
A volume-to-pressure measurement of lung distensibility with exhalation against a closed system, taken under conditions of no airflow. It can be represented mathematically as: Tidal volume/Pplat-total PEEP (positive end-expiratory pressure).
