Abstract
An apparatus and method for assisting cardiac function of a patient includes a flaccid inflatable chamber held at a predetermined volume generally midway between fully inflated and fully deflated for performing a periodically scheduled patient monitoring routine for measuring values of the physiology of the patient, and reinflating the chamber after either detecting a dicrotic notch or expiration of a measurement time period window, whichever occurs first. A software program is connectible in electronic communication with the control program for adjusting settings of the drive unit. The software program is capable of one or more of the following functions: retrieving current values of physician programmable parameters, selectively retrieving a history of the drive unit operation including error detection records, displaying a continuous ECG, and/or displaying a single-beat sample of aortic pressure waveform obtained in real time from the patient.
