Abstract:
1. Pulsatile measurement apparatus for application to a limb of a person, the apparatus comprising: at least one cuff selected from the group consisting of: at least one of the pressure cuffs provided with an inflatable bladder and cuff pressure system and means for generating external pressure pulses, with means for timing the pressure pulses to occur during diastolic phase of the person's blood pressure pulse; at least one of the pressure cuffs connected to a pressure bulb, a release valve, and an analog pressure gauge with an electronic pressure transducer providing electric signals indicative of pressure, with means for appropriate calibration; whereby mechanical plethysmographic measurements are made on output signals from pulse pressure; at least one of said pressure cuffs having four aluminum electrodes on the inside of the cuff, with electrical leads connected to the four electrodes, with said electrical leads providing electric plethysmographic output signals from pulse pressure; and signal processing means connected to the electric plethysmographic output signals and pressure transducer output signals from said pulse pressure for computing and displaying values relevant to conditions contributory to cardiac malfunction.
