Prone position ventilation is a postural therapy to improve oxygenation in patients with severe Acute Respiratory Distress Syndrome (ARDS).In pregnant women with severe ARDS, prone position ventilation can, to a certain extent, alleviate the collapse of the lung region, reduce the pressure of the gestational uterus, and improve patients′ oxygenation.This study reviews the existing successful case reports on prone position ventilation in pregnant women with severe ARDS, in order to summarize its care in terms of clinical differences, mechanism of action, clinical application, illness condition observation and application effect, and to provide a reference for clinical intervention.
