Details and patient eligibility

About

Changes in volumetric hemodynamic parameters and fluid overload (Cardiac Index,Stroke Volume, Thoracic Fluid Content, Systemic Vascular Resistance) were measured using a impedance cardiography (ICG) (CardioScreen 1000 - Haemodynamic Measurement System, Medis. GmbH Ilmenau) while lifting the leg at different angles. The measurement lasted 12 minutes.
