Abstract
Treatment systems for nocturnal hypoxia in cardiovascular patients are described herein. Generally, the system may include one or more sensors configured to be implanted within a subject and a controller in communication with the one or more oximetry sensors, wherein the controller is programmed to predict a change in oxygen saturation indicative of hypoxia in the subject by identifying one or more patient-specific features from a polysomnography of the subject and correlating the one or more patient-specific features to data received from the one or more sensors.

A system for treating nocturnal hypoxia, comprising:
- one or more sensors configured to be implanted within a subject,
- a controller in communication with the one or more oximetry sensors, wherein the controller is programmed to predict a change in oxygen saturation indicative of hypoxia in the subject by identifying one or more subject-specific features from a polysomnography of the subject and correlating the one or more subject-specific features to data received from the one or more sensors;
- and
- one or more electrodes in communication with the controller, wherein the one or more electrodes are configured for placement against tissue associated with respiration of the subject and are further configured to deliver a stimulation to the tissue in response to the predicted change in oxygen saturation.
A method for treating nocturnal hypoxia, comprising:
- monitoring respiration and heart rate within a phrenic nerve stimulation device implanted within a subject;
- predicting a potential reduction in oxygen saturation during sleep of the subject via a controller programmed to predict a change in oxygen saturation indicative of hypoxia in the subject by identifying one or more patient-specific features;
- and
- stimulating a phrenic nerve and/or diaphragm via one or more electrodes in communication with the controller for a period of time in response to the predicted change until an oxygen saturation level within the subject is normalized and hypoxia is mitigated.
