Lung CT images were obtained while tracing the curve in static conditions. Note that recruitment only starts when airway pressure is higher than the lower inflection point (LIP) of the inspiratory limb and continues up to the maximum pressure reached, even above the upper inflection point (UIP). There is, however, no de-recruitment when airway pressure decreases from this level to the expiratory point of maximum curvature (PMC). With pressures below this point, de-recruitment starts and continues along the rest of the expiratory limb of the curve. From Reference 73, with permission.
