METHOD AND DEVICE FOR DETECTING RESPIRATORY DISTURBANCES

摘要

A system and method is disclosed for monitoring respiration including sensing a signal that varies with respiration, deriving a respiration parameter, applying criteria for detecting a respiration disturbance and determining one or more respiratory disturbance metrics. The system preferably includes an implantable sensor with an associated implantable medical device such that chronic respiration monitoring is possible. The implantable medical device may execute methods for detecting and measuring respiratory disturbances or may store data to be transferred to an external device for detecting and measuring respiratory disturbances. Respiratory disturbance detection may trigger a responsive action such as physiological data storage, a change in therapy, or a clinician warning. Assessment of cardiac function may be made on metrics of respiratory disturbances or a measure of circulatory delay time following detection of a respiratory disturbance.
