Abstract

In the critical care setting, positioning is a fundamental tool for implementing an integrated respiratory care strategy. Conversion from the upright to the near-horizontal position used in intensive care is accompanied by important changes in ventilation, perfusion, oxygenation and secretion clearance. These effects are largely accounted for by the influence of gravity on perfusion distribution and by the shifting of pressure vectors as the tissues surrounding the lungs reconfigure. Re-positioning aids or impairs muscle function, affects secretion drainage, influences gas trapping and alters the development or redistribution of lung collapse. Many of these phenomena hold implications for the expression of disease or its management. Mechanical ventilation, sedation, intra-abdominal and intracranial hypertension — common therapies and problems confronted in the intensive care unit (ICU) — are strongly influenced by body orientation.
