Daytime/nighttime respiration rate monitoring
First Claim
1. A method comprising:
- detecting a respiration signal from a subject;
determining respiration rate or interval measurements from the respiration signal;
classifying the respiration rate or interval measurements into at least one class of respiration rate or interval measurements, and associating a specified time of day with at least one class;
trending at least one of;
(1) time of day of occurrence information about the classified respiration rate or interval measurements, or (2) respiration rate or interval measurement information repeatedly, over a period of multiple days, during a specified one of a daytime subperiod or a nighttime subperiod, wherein the specified one of the daytime subperiod or the nighttime subperiod corresponds to a like time of day during each of the multiple days; and
providing a heart failure decompensation indication using the trended information.

Abstract
A device and method can monitor or trend a patient'"'"'s respiration rate measurements according to the time of day. The device, which may be implantable or external, collects and classifies respiration rate measurements over time. The trended information about particular classes of respiration rate measurements is then communicated to a remote external device, which in turn provides an indication of heart failure decompensation. Examples of classes of respiration rate measurements include a daily maximum respiration rate value, a daily minimum respiration rate value, a daily maximum respiration rate variability value, a daily minimum respiration rate variability value, and a daily central respiration rate value. These respiration rate measurements can be further classified into daytime or nighttime respiration rate measurements.
