the quality of recoiling on removal of pressure without disruption, or an expression of the measure of the ability to do so in terms of unit of volume change per unit of pressure change; it is the reciprocal of compliance.
A measure of the tendency of a structure to return to its original form after removal of a deforming force. In medicine and physiology, usually a measure of the tendency of a hollow viscus (for example, lung, urinary bladder, gallbladder) to recoil toward its original dimensions on removal of a distending or compressing force, the recoil pressure resulting from a unit distention or compression of the viscus; the reciprocal of compliance. The relationship between elasticity and elastance is of the same nature as that between the specific inductive capacity of an insulator material and the capacitance of a particular condenser made from that material.
1. A measure of the stiffness of a chamber expressed as a change in pressure per unit change in volume; the reciprocal of compliance.
2. internal medicine, physiology Usually a measure of the tendency of a hollow viscus (e.g., lung, urinary bladder, gallbladder) to recoil toward its original dimensions on removal of a distending or compressing force.
