Question

Quizplus · Accepted Answer

Functional residual capacity (FRC) measures the amount of air left in the lungs after a resting expiration. This measurement is ideal for preventing chest wall and lung recoil pressures from contributing to the pressure generated by the inspiratory muscles. Residual capacity (RC) and total lung capacity (TLC) are not ideal because they involve either complete emptying or complete filling of the lungs, which can lead to pressure from the chest wall and lungs. Inspiratory reserve (IR) measures the maximum amount of air that can be taken in after a normal breath, which is not necessarily helpful in preventing chest wall and lung recoil pressures.
