Abstract
Medical devices and methods for providing breathing therapy (e.g., for treating heart failure, hypertension, etc.) may determine at least the inspiration phase of one or more breathing cycles based on the monitored physiological parameters and control delivery of a plurality of breathing therapy sessions (e.g., each of the breathing therapy sessions may be provided during a defined time period). Further, each of the plurality of breathing therapy sessions may include delivering stimulation after the start of the inspiration phase of each of a plurality of breathing cycles to prolong diaphragm contraction during the breathing cycle.
Claims31
A medical device for providing breathing therapy comprising:
- monitoring apparatus configured to monitor one or more physiological parameters of a patient;
- a therapy delivery module configured to deliver electrical stimulation to a patient in which the presence of a temporary or sustained elevated sympathetic tone has been determined, wherein the elevated sympathetic tone is determined based at least on an elevated blood pressure;
- and
- a control module configured to:
- determine at least the inspiration phase of one or more breathing cycles based on the monitored physiological parameters;
- and
- control delivery of a plurality of breathing therapy sessions, wherein each of the breathing therapy sessions is provided during a defined time period, and further wherein each of the plurality of breathing therapy sessions comprises delivering stimulation after the start of the inspiration phase of each of a plurality of breathing cycles to prolong diaphragm contraction during the breathing cycle,
- wherein the therapy module is further configured for delivering cardiac stimulation, wherein the control module is configured to control delivery of cardiac pacing to the patient based on predefined ratios of breathing rate to heart rate.
A method for providing breathing therapy, comprising:
- monitoring one or more physiological parameters of a patient to determine the presence of a temporary or sustained elevated sympathetic tone based on at least an elevated blood pressure;
- monitoring respiration of a patient to determine at least the inspiration phase of one or more breathing cycles;
- and
- providing a plurality of breathing therapy sessions upon determination of the presence of an elevated sympathetic tone, wherein each of the breathing therapy sessions is provided during a defined time period, and further wherein each of the plurality of breathing therapy sessions comprises delivering stimulation after the start of the inspiration phase of each of a plurality of breathing cycles to prolong diaphragm contraction during the breathing cycle,
- wherein each of the plurality of breathing therapy sessions further comprises delivering cardiac pacing to the patient based on a predefined ratio of breathing rate to heart rate.

- means for monitoring one or more physiological parameters of a patient to determine the presence of a temporary or sustained elevated sympathetic tone based on at least an elevated blood pressure;
- means for monitoring respiration of a patient to determine at least the inspiration phase of one or more breathing cycles;
- and
- means for providing a plurality of breathing therapy sessions upon determination of the presence of an elevated sympathetic tone, wherein each of the breathing therapy sessions is provided during a defined time period, and further wherein each of the plurality of breathing therapy sessions comprises delivering stimulation after the start of the inspiration phase of each of a plurality of breathing cycles to prolong diaphragm contraction during the breathing cycle,
- wherein each of the plurality of breathing therapy sessions further comprises delivering cardiac pacing to the patient based on a predefined ratio of breathing rate to heart rate.
