Chapter 2, Problem 2CAQ5
Case 2
A product of the time constants is the measurement called dynamic compliance, which is the change in volume of the lungs divided by the change in the transpulmonary pressure during the time for one breath. During an asthmatic episode, the patient's dynamic compliance (increases _________; decreases ___________________; remains thesame____________________).
