AbstractAcute respiratory distress syndrome (ARDS) is often associated with severe hypoxemia and a high mortality rate. Prone positioning is a well-established intervention for ARDS. It has been shown to improve oxygenation and prevent ventilator-induced lung injury due to the more uniform distribution of lung stress and strain. This narrative review aims to compare the various factors that may influence how prone positioning affects mortality rates. We will examine the duration of time a patient is in the prone position, severity of ARDS, use of lung-protective ventilation, and the time elapsed between ARDS diagnosis and placing a patient in the prone position. A literature review on prone positioning in ARDS was performed and searched data from PubMed and Google Scholar for articles published from 2010 to 2020. Although no single variable used during prone positioning reduces mortality rates in ARDS patients, combining several optimal conditions may yield increased survival benefits. Early initiation of extended prone positioning sessions combined with low tidal volumes shows encouraging results in severe ARDS patients. Future research on this subject should focus on further examining these variables in a study enrolling a larger number of subjects in a setting with adequately trained staff familiar with proper prone positioning techniques.Copyright © 2020, Dardeir et al.
