Abstract
An implantable respiration monitor can be used to detect disordered breathing or periodic 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 also 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 therapy or to display one or more trends. The alert can notify the patient or a caregiver, such as via remote monitoring. The sleep state information can be further categorized according to central sleep apnea (CSA) or obstructive sleep apnea (OSA) events.
