Abstract
Method and apparatus are provided for computing signals related to cardiac output from physiologic input signals related to circulatory pressures or flows. Method and apparatus are provided for constructing a transforming filter and applying said filter to the physiologic input signals in order to obtain a signal proportional to phasic cardiac output or time-averaged cardiac output. This invention provides a means for real-time monitoring of cardiac output and stroke volume which is of great clinical importance but not otherwise feasible by present techniques.
