A Cochrane review [Abstract] 1 included 24 studies with a total of 581 subjects. These studies compared prone, supine, lateral, elevated, and flat positions. Prone positioning was significantly more beneficial than supine positioning in terms of oxygen saturation, arterial oxygen, episodes of hypoxaemia, and thoraco-abdominal synchrony. There were no statistically significant differences between any other positions.
Comment: The quality of evidence is downgraded by study quality (inadequate or unclear allocation concealment).
