Periodic breathing during activity
First Claim
1. A method comprising:
- monitoring respiration of a subject;
detecting physical activity of the subject;
obtaining a respiration pattern of the subject during the activity;
analyzing how well the respiration pattern fits a model, the analyzing providing a goodness of fit indication;
identifying a disordered breathing during activity indication from the goodness of fit indication; and
providing the disordered breathing during activity indication to a user or automated process.

Abstract
An implantable respiration monitor can detect disordered breathing events that can be categorized, such as according to one or more of sleep, exercise, and resting awake states. The categorized frequency of such events can be compared to independently specifiable thresholds, such as to trigger an alert or responsive therapy, or to display one or more trends. The information can be combined with detection of one or more other congestive heart failure (CHF) symptoms to generate a CHF status indicator or to trigger an alarm or responsive. The alert can notify the patient or a caregiver, such as via remote monitoring. Respiration patterns from one or more of the activity states can be used to establish model of disordered breathing to which further respiration data can be compared for identifying periods of disordered breathing. Such identification can trigger an alert or response to therapy, or to display one or more trends.

16. A system comprising:
-
an activity detector, configured to detect a physical activity indication of a subject;
a respiration monitor, configured to obtain respiration pattern data of the subject during the activity;
a processor circuit, coupled to at least one of the activity detector and the respiration monitor, the processor configured to analyze how well the respiration pattern data during activity fits a model to provide a resulting goodness of fit indication, the processor configured to use the goodness of fit indication to determine and provide a periodic breathing during activity indication. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
