Cardiac Output and Filling Pressures at Rest and During Exercise
Ventricular function in man can be described by the relationship between filling pressure and cardiac output at rest and during exercise. Mean filling pressures of the left ventricle can be measured as pulmonary wedge pressure (PCP). Cardiac output can be determined by a modified Fick principle, measuring only mixed venous oxygen saturation and using age-dependent normal values of oxygen consumption for different exercise loads. Both parameters can easily be measured by means of a Swan Ganz floating catheter. Exercise is performed on a bicycle ergometer in recumbent position. There is a very low risk with the Swan Ganz floating catheter procedure.
