Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-facilitated method for visually representing to a medical practitioner a cardiac status of a patient so as to facilitate a determination by the medical practitioner of 1) a need for a cardiac-related intervention and/or 2) an effect of a prior cardiac-related, intervention, the method comprising: A) measuring, via a sensing device coupled to the patient, a circulatory parameter of the patient so as to provide, as an output of the sensing device, a…
