Abstract:
Positioning critically ill patients is a frequently used intervention in nursing practice. However, positioning can have a beneficial or adverse effect depending on the effect on oxygen delivery and oxygen consumption. This article examines the physiologic effect of positioning on the balance between oxygen delivery and oxygen consumption. In addition, a critical analysis of the research on the effect of positioning on mixed venous oxygen saturation is presented. Recommendations for patient management are discussed as well as the implications for future research.
