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.

Claims

1. 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 respiratory sinus arrhythmia (RSA),

wherein the sensed parameters acquired from the implantable medical device includes sensed heart rate and sensed respiration, and using the sensed physiological parameters to generate the composite parameter indicative of RSA includes using a function of the sensed heart rate and the sensed respiration to generate the composite parameter indicative of RSA.

2. The system of claim 1, further comprising a trending module configured to trend the composite parameter and one or more of the sensed physiological parameters sensed by the implantable medical device.

3. The system of claim 2, wherein the system includes a display and the method performed by the programmable device includes displaying one or more trends of the composite parameter on the display.

4. The system of claim 2, wherein the method performed by the programmable device includes acquiring a patient context or environmental context, wherein the trending module is configured to trend the patient context or environmental context with the composite parameter.

5. The system of claim 4, wherein, in the method performed by the programmable device, acquiring the patient context or environmental context includes acquiring a patient context selected from the group of patient contexts consisting of posture, activity level, sleep/wake state, and mental/emotional state.

6. The system of claim 4, wherein, in the method performed by the programmable device, acquiring the patient context or environmental context includes acquiring an environmental context selected from the group of environmental contexts consisting of temperature, sound, altitude, air quality, pollen count, humidity, environmental pressure, and time of day.

7. The system of claim 1, wherein the device includes a wellness monitoring device within an advanced patient management system.

8. The system of claim 1, wherein the sensed respiration acquired from the implantable medical device includes a sensed parameter related to instantaneous lung volume from a trans-thoracic sensor.

9. 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 comprising;

acquiring from the implantable medical device a heart rate parameter and a parameter related to instantaneous lung volume; and

generating a composite parameter indicative of respiratory sinus arrhythmia (RSA) using the heart rate parameter and the parameter related to instantaneous lung volume.

10. The system of claim 9, wherein the device includes a wellness monitoring device within an advanced patient management system.

11. The system of claim 9, wherein, in the method performed by the programmable device, acquiring the patient context or environmental context includes acquiring a patient context selected from the group of patient contexts consisting of posture, activity level, sleep/wake state, and mental/emotional state.

12. The system of claim 9, wherein the method performed by the programmable device includes acquiring an environmental context selected from the group of environmental contexts consisting of temperature, sound, altitude, air quality, pollen count, humidity, environmental pressure, and time of day.

13. The system of claim 9, wherein the system includes a display and the method performed by the programmable device includes displaying one or more trends of the composite parameter on the display.
