METHODS AND SYSTEMS FOR ADVERSE EVENT PREDICTION USING PUMP OPERATING DATA

摘要

The present disclosure provides for each of a method of characterizing divergence of a monitored flow rate of blood through an implantable blood pump, and a method of predicting an upcoming adverse cardiac event using operating data of the blood pump, such as the characterized divergence data. Predicting an upcoming adverse cardiac event may be further based on similar operating data from a plurality of other implantable blood pumps.

1. A method of characterizing divergence of a monitored flow rate of blood through an implantable blood pump, comprising repeatedly performing over time: (i) determining a flow rate of blood through the pump at a then-current time, (ii) calculating an average flow rate of blood through the pump over a first period of time preceding the then-current time, (iii) calculating a divergence value, which is representative of a difference between the average flow rate and the determined then-current flow rate, wherein the divergence of flow rate is characterized based on a sum of the calculated divergence values.
