Effective ventilation strategies are crucial in critical care, focusing on optimizing oxygenation and ventilation while minimizing lung injury; The Principles of Critical Care Medicine, 5th Edition emphasizes evidence-based approaches, including lung-protective ventilation with low tidal volumes and positive end-expiratory pressure (PEEP). Advanced modes such as airway pressure release ventilation (APRV) and high-frequency oscillatory ventilation (HFOV) are discussed for refractory hypoxemia. The text also explores the role of non-invasive ventilation (NIV) in reducing intubation rates and complications. Personalized ventilation strategies, tailored to patient-specific pathophysiology, are highlighted to improve outcomes and reduce ventilator-associated complications in the ICU setting.

4.2 Acute Respiratory Distress Syndrome (ARDS)

Acute Respiratory Distress Syndrome (ARDS) is a severe condition characterized by rapid onset of hypoxemia and pulmonary edema. The Principles of Critical Care Medicine, 5th Edition details its pathophysiology, diagnosis, and evidence-based management. Diagnostic criteria include the Berlin Definition, emphasizing timing, respiratory failure, and parenchymal injury on imaging.
