Abstract
An apparatus for assessing cardiovascular status of a mammal comprises a system for locally applying a pressure to an artery capable of restricting blood flow through said artery, a wideband external pulse transducer having an output and situated to measure suprasystolic signals proximate to said artery, and a computing device receiving said output for calculating vascular compliance values. The method described is particularly useful for determining cardiac output, assessing whether a pregnant female has preeclampsia or a patient has cardiac insufficiency, or assessing cardiac arrhythmia.
Claims15
An apparatus for assessing a cardiovascular system of a mammal comprising:
- a cuff for occluding systolic blood flow through a brachial artery of the mammal;
- a transducer having an electronic output signal representing a suprasystolic blood pressure waveform in tissue subject to a blood flow occlusion by said cuff;
- and
- a computing device receiving said output signal, analyzing a temporal and amplitude variation thereof, and determining a value representing large arterial vascular compliance in the mammal.
