Method and apparatus for management of heart failure hospitalization
First Claim
Patent Images
1. A system for managing a heart failure patient, the system comprising:
- a sensor processing circuit configured to receive one or more physiological signals and produce sensor data representative of the one or more physiological signals; and
a heart failure analyzer circuit coupled to the sensor processing circuit, the heart failure analyzer configured to operate in a post-hospitalization mode including to;
receive diagnostic data including information about the sensor data, the diagnostic data indicative of one or more conditions associated with heart failure decompensation, wherein the diagnostic data includes post-hospitalization respiration data associated with the patient; and
produce a risk class parameter classifying a level of risk for rehospitalization within a specified period using the diagnostic data.

Abstract
A hospitalization management system including a heart failure analyzer that receives diagnostic data including at least sensor data representative of one or more physiological signals sensed from a hospitalized patient using one or more sensors and assesses risk of rehospitalization for the patient using the diagnostic data. The outcome of the risk assessment is used during and following the patient'"'"'s hospitalization for reducing the risk of rehospitalization.
