The FRC is the volume of air left in the lungs at the end of passive expiration. From this, it stands to reason that any impediment to expiratory air flow should increase this volume of air, by standing in the way of its exit.

WebChronic lung disease might increase VD / VT to ≥0.8; in this case, a minute ventilation of ≥25 L·min −1 is required for an effective alveolar ventilation of 5 L·min −1. Measures of wasted ventilation, thus, estimate the effect of V ′ A/Q ′ mismatch on the minute ventilation needed to maintain adequate gas exchange.
