WebAlveolar overdistension occurs at the upper inflection point (UIP). A small increase in tidal volume beyond this will increase pressure significantly and lead to alveolar overdistension, putting patients at high risk of VILI (Figures 32 and 33). 2,12,17,29; Figure 32: WebAn increase in the respiratory rate and a decrease in tidal volume indicate a pattern of rapid shallow breathing. If the total ventilation does not change, alveolar ventilation will decrease because of the fact that the first 150 ml of each inspiration is dead-space breathing. An increase in the rate means an increase in dead-space breathing.
