System and method for managing respiratory insufficiency in conjunction with heart failure assessment
First Claim
1. A system for managing respiratory insufficiency in conjunction with heart failure assessment, comprising:
- a data module to assemble physiological measures, which were directly recorded as data on a substantially continuous basis by a medical device for a patient or indirectly derived from the data;
a status module to determine a wellness indicator for the patient through sampling and analysis of the physiological measures over a plurality of data assembly points; and
an evaluation module to evaluate the physiological measures relative to the wellness indicator, comprising;
an analysis module to analyze a patient status trend comprising one of a status quo and a change in at least one of cardiac performance and respiratory performance; and
a comparison module to compare the patient status trend to applicable indications of worsening heart failure and respiratory insufficiency, wherein the evaluation module further evaluates a time span over which the patient status trend occurs;
an indicator module to define stickiness indicators comprising a temporal bound on change of one or more of the physiological measures, anda revision module to revise patient treatment in a manner corresponding to a rate of the patient status trend over the time span.

Abstract
A system and method for evaluating a patient status from sampled physiometry for use in respiratory insufficiency management and heart failure assessment is presented. Physiological measures are stored and include direct measures regularly recorded on a substantially continuous basis by a medical device for a patient or measures derived from the direct measures. The physiological measures are sampled, which each relate to a same type of physiometry, and those of the physiological measures, which each relate to a different type of physiometry. A status is determined through analysis of those sampled physiological measures assembled from a plurality of recordation points. The sampled physiological measures are evaluated. Any trends are identified and include one of a status quo and a change, which might affect cardiac performance or respiratory performance. Each such trend is compared to applicable indications of worsening heart failure and respiratory insufficiency to generate a notification of parameter violations.
