There are a variety of ventilator options available to the emergency clinician, and decisions on choosing optimal settings will depend on the clinical circumstances. Understanding the latest literature in ventilator management can improve patient outcomes by ensuring optimal oxygenation and ventilation and reducing the potential for ventilator-induced lung injury. This article reviews the most appropriate ventilator settings for a variety of conditions in intubated adult patients presenting to the emergency department, and gives recommendations on monitoring the ventilated patient and making ventilator adjustments. An update on managing COVID-19-associated acute respiratory distress syndrome is also included.
