ASSESSING PATIENT RISK FOR AN ACUTE HYPOTENSIVE EPISODE

摘要

What is disclosed is a system and method for assessing patient risk for an acute hypotensive episode. In one embodiment, the present method involves retrieving a training set from a database. The training set comprises mean arterial pressures (MAPs) for a plurality of subjects. Each MAP comprises systolic and diastolic measurements. The training set is used to train the present classifier system. Once trained, the present classifier system classifies an unclassified patient into either a first class or a second class. The first class is at risk for an acute hypotensive episode occurring within a prediction window of w≧60 minutes in the future. The second class is not at risk for an acute hypotensive episode. A MAP of an unclassified patient is retrieved or otherwise obtained. Thereafter, the present classifier system proceeds to classify the patient into the first or second class. Various embodiments are disclosed.

1. A method for assessing patient risk for an acute hypotensive episode, the method comprising:
using a training set of mean arterial pressures (MAPs) for a plurality of subjects to train a classifier system, said classifier system classifying an unclassified patient into one of: a first class where said patient is identified as being at risk for an acute hypotensive episode occurring within a timeframe of a prediction window of w minutes in the future, and a second class where said patient is identified as not being at risk for an acute hypotensive episode, each MAP comprises systolic and diastolic measurements of subjects in both of said first and second classes; obtaining at least one MAP of an unclassified patient; and using said classifier system to classify said unclassified patient into one of said first and second classes.
