A cardiac monitor combining flow and pressure measurement.
Continuous measurements on patients after cardiac surgery are usually limited to blood pressure and ECG. This article describes a new monitor which combines instantaneous arotic flow and arterial pressure measurements to derive stroke volume, ventricular power, stroke work, and an indication of left ventricular afterload. The methods used to obtain the new derivatives are discussed and clinical applications described.
