Abstract
Systems, devices and methods for defining, identifying and utilizing composite parameter indices from health-related parameters are disclosed. One aspect is a programmable device having machine executable instructions for performing a method to assist with managing a patient's health. In various embodiments, a first set of at least two health-related parameters is acquired. A first composite parameter is generated using the first set of at least two health-related parameters. Other aspects and embodiments are provided herein.
Claims27
A system for monitoring a heart failure status of a heart failure patient, comprising:
- an implantable medical device;
- and
- a programmable device having machine executable instructions for performing a method to assist with managing a patient's health, the method performed by the programmable device including acquiring from the implantable medical device sensed physiological parameters, and using the sensed physiological parameters to generate a composite parameter indicative of a degree of dyspnea, wherein using the sensed physiological parameters to generate the composite parameter indicative of the degree of dyspnea includes using a ratio (PRR/PTV) of a respiration rate parameter (PRR) to a tidal volume parameter (PTV) to provide an index for the degree of dyspnea.
