The effects of patient positioning on hemodynamic parameters
Abstract:Elevation of legs increases stroke volume (SV) as the blood moves into the intrathoracic compartment. However, the degree of effects caused by the increase in blood remains controversial as it only has temporary effect. As for hemodynamically unstable patients, special positioning and hemodynamic monitoring are essential. We investigated the effective posture to increase SV and the relationships between the hemodynamic parameters and the changes in the SV by adjusting the upper and the lower body angles.
