APPARATUS AND METHOD FOR NON-INVASIVE MONITORING OF CARDIAC PERFORMANCE

摘要

A non-invasive apparatus for measuring cardiac mechanical performance of a patient, the apparatus comprising a pressure applying element mountable on a limb of the patient for applying pressure high enough to make a segment of an artery within the limb achieve a collapsed state and empty it from blood at least momentarily; at least one of a plurality of sensors coupled to said pressure applying element, sensing mechanical changes corresponding to volumetric changes in the artery as the artery progressively recuperates from its collapsed state; processing unit communicating with said at least one of a plurality of sensors for receiving output corresponding to the mechanical changes from said at least one of a plurality of sensors and computing factors correlated with blood flow and calculate parameters indicating heart performance.
