Venous return in the circulatory system of lower limbs results from the interaction of several mechanisms, and reflects the balance between blood inflow and outflow. Blood outflow improves during sleeping because of the lying position especially with leg elevation. In fact, patients with chronic venous disease (CVD) improve leg symptoms in lying position and with leg elevation. The aim of this study is to evaluate the level of comfort of hospital inpatients, without CVD, if they lie with a moderate leg elevation during hospital stay.
