WebInspiratory Reserve Volume (IRV) — amount of air that can be inspired with maximal effort after normal tidal breathing. Can vary from 1500 — 2500 cc. Expiratory Reserve Volume (ERV) — volume of air that can be forced out of lugs with maximal effort after normal tidal breathing. Usually around 1500 — 2000 cc in a young adult. WebInverse-ratio ventilation (IRV) is positive-pressure ventilation with an inspiratory-expiratory (I : E) ratio of greater than 1. It has been used in the management of severe ARDS to improve oxygenation when PEEP has been optimized. 46 I : E ratios usually range from 1.2 to 1.5, whereas in IRV, they may be 1 : 1, 2 : 1, or higher.
