static hysteresis

 

Definition: the difference in the value reached by a dependent variable at a particular constant value of the independent variable, depending on whether the latter value had been approached from above or below; in measuring the pressure volume relations of the lungs, if one completely expires and then inspires to a particular volume and holds it constant, the transpulmonary pressure required to maintain that lung volume is greater than if one had completely inspired and then expired to the same volume and held it constant.
