Method and System for Predicting of Acute Hypotensive Episodes

摘要

A method and system of predicting a hypotensive episode in a patient using one or more time varying hypotension specific biomarkers corresponding to physiological processes in the patient. Data derived from sensors or other measurement devices such as ECG sensors can be used to generate biomarkers. The biomarkers can then be used to generate an acute hypotension prediction classifier, or monitored factor, derived from a three dimensional temporal representation of two or more biomarkers. When the monitored factor exceeds a predetermined threshold the method and system trigger an alarm before an appearance of a hypotensive episode in the patient.

1. A method for predicting an acute hypotensive episode of a patient comprising:
attaching ECG sensors to a patient; transmitting ECG signals generated by the sensors attached to the patient, over a number of cardio cycles, to an ECG device comprising a processor, software, storage, and a threshold alarm value stored in said storage; processing the ECG signals using the processor to calculate data for each cardio cycle; forming matrixes for each cardio cycle using the calculated data; calculating biomarkers using calculated data; generating a monitored factor using said biomarkers; comparing said monitored factor to a threshold alarm value for said monitored value; triggering an alarm when said threshold alarm value is exceeded by said monitored factor.
