Claim:
1. A non-transitory device-readable storage medium including instructions that, when performed by one or more devices, cause the one or more devices to perform acts comprising: detecting a respiration signal from a subject using a respiration sensor; determining respiration rate or interval measurements from the respiration signal; classifying the respiration rate or interval measurements into daytime respiration rate or interval measurements or nighttime respiration rate or interval measurements using a first classifier circuit; classifying the daytime respiration rate or interval measurements into two or more daytime subclasses of statistical measurements of respiration rate or interval measurements, or classifying the nighttime respiration rate or interval measurements into two or more nighttime subclasses of statistical measurements of respiration rate or interval measurements using a second classifier circuit; trending the classified daytime subclasses or nighttime subclasses of respiration rate or interval measurements over a period of multiple days; generating a diagnostic indicator of heart failure decompensation using a statistical measure of the trended daytime subclasses or nighttime subclasses of respiration rate or interval measurements; and providing instructions to display the diagnostic indicator to guide a heart failure therapy.
