Macroscopic histological changes in a porcine model of airway pressure release ventilation (APRV) vs low tidal volume ventilation (LTV). This figure has been reproduced with permission from Shock. Gross pathology: (A) APRV whole lung – normal pink, homogenously inflated lung tissue with no evidence of inflammation or atelectasis. (B) APRV cut surface – no bronchial or septal oedema. (C) LTV whole lung – predominantly atelectatic with heterogenous parenchymal inflammation. (D) LTV cut surface – gel-like oedema seen filling the interlobular septae with airway oedema in the bronchial openings.

Adjustment of T-low to terminate expiratory flow at 75% of peak flow. Reproduced with permission from Shock. (A) Correct T-low settings (0.4 s). (B) Incorrect T-low settings (0.6 s).
