Mechanical ventilation is the primary supportive, invasive measure utilized in patients with acute respiratory distress syndrome. Throughout the years, many large multicenter randomized controlled trials and observational studies were analyzed to determine what ventilator parameters to use that would produce a mortality benefit after initial diagnosis. This article discusses the concepts of ventilator-induced lung injury, permissive hypercapnia, high-versus-low peep strategies, oxygenation goals, and recruitment strategies from a physiologic perspective and the major studies that produced recommendations for each. Newer concepts, such as driving pressure, are also discussed.
