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: WebMinute ventilation (VE) is the total volume of gas entering (or leaving) the lung per minute. It is equal to the tidal volume (TV) multiplied by the respiratory rate (f). Minute ventilation = VE = TV x f At rest, a normal person moves ~450 ml/breath x 10 breath/min = 4500 ml/min.
