Evidence-based guideline for lung-protective ventilation, prone positioning, PEEP optimization, rescue therapies, and ventilator liberation in acute respiratory distress syndrome.
Acute respiratory distress syndrome (ARDS) remains among the most formidable challenges in critical care medicine. Characterized by acute-onset, diffuse, inflammatory pulmonary edema leading to refractory hypoxemia, ARDS carries a mortality rate of 35 to 46 percent depending on severity, with the most severe forms historically exceeding 50 percent mortality.12 Over the past two decades, a series of landmark randomized controlled trials and systematic reviews have established an evidence-based framework for ventilatory management that has meaningfully reduced mortality and morbidity. These advances — lung-protective ventilation, prone positioning, conservative fluid management, structured ventilator liberation protocols, and selective use of adjunctive therapies — form the foundation of modern ARDS care.
This guideline synthesizes recommendations from multiple authoritative professional societies, multicenter clinical trials, expert consensus panels, and systematic reviews into a single, comprehensive clinical reference. It is intended for intensivists, pulmonologists, emergency physicians, anesthesiologists, respiratory therapists, critical care nurses, and advanced practice providers involved in the care of mechanically ventilated patients with or at risk for ARDS. Recommendations reflect the current evidence base through early 2026 and incorporate guidance from major critical care professional societies, the ARDS network investigators, and European and international ventilation consensus groups.123456
The guideline covers the complete trajectory of ARDS management — from initial recognition and Berlin criteria classification through ventilator setup, lung-protective strategies, prone positioning, adjunctive therapies, rescue interventions including extracorporeal membrane oxygenation, non-invasive respiratory support, ventilator liberation, and etiology-specific considerations. Every recommendation is grounded in published evidence, with specific numerical parameters, protocols, and decision frameworks suitable for direct clinical application.
