System and Method for Generating a Trend Parameter Based on Respiration Rate Distribution
First Claim
1. A method, comprising:
- detecting respiration of a patient over a period of time;
computing a plurality of respiration rates for the period of time based on the detected patient respiration;
calculating a distribution of the respiration rates based on the plurality of respiration rates;
determining the patient'"'"'s rapid shallow breathing (RSB) burden for the time period using the respiration rate distribution, the RSB burden characterized by rapid shallow breathing of the patient during the time period; and
producing an output indicative of the patient'"'"'s heart failure status based on the patient'"'"'s RSB burden.

Abstract
Systems and methods provide for assessing the heart failure status of a patient and, more particularly, to generating a trend parameter based on a distribution of the patient'"'"'s respiration rate. Systems and methods provide for detecting, using an implantable device or a patient-external device, patient respiration and computing a respiration rate based on the detected patient respiration. A distribution of the respiration rate is calculated, and a trend parameter based on the respiration rate distribution is generated. The trend parameter is indicative of a patient'"'"'s heart failure status. An output signal indicative of the patient'"'"'s heart failure status may be generated based on the trend parameter.
