Prone position seems to be a promissing strategy to improve the hypoxemia in patients with acute lung injury and severe acute respiratory distress syndrome. Previous works have shown that, while in prone position, there is a ventilation of areas that once were in atelectasis. This ventilation is accompanied by a redistribution of blood flow, with a reduction of the intrapulmonary shunt and, therefore, an improvement of the ventilation/ perfusion relation. The authors review the use of prone position, its indications and contraindications, as well as the mechanisms involved in the oxygenation improvement.
