Abstract
The present disclosure generally relates to systems and methods for detecting and/or treating obstructive sleep apnea (OSA) experienced by a subject, using one or more implanted or external sensors. In some aspects, the systems and methods described herein are configured to classify the human subject as being awake or asleep by comparing a calculated standard deviation and/or variance of one or more respiratory parameters against a predetermined threshold and to control the delivery of stimulation based on this classification.
Claims29
A implantable system for treating obstructive sleep apnea (OSA) in a human subject, comprising:
- an inertial measurement unit (IMU);
- and
- a controller communicatively linked to the IMU and configured to:
- receive sensor data from the IMU, and
- determine a position of the human subject from the sensor data;
- and
- a stimulation system, communicatively linked to the controller and configured to deliver stimulation to a nerve which innervates an upper airway muscle of the human subject;
- wherein the stimulation system is configured to activate the delivery of stimulation to the nerve when the controller detects a transition in the position of the human subject.
A method for treating obstructive sleep apnea (OSA) in a human subject comprising:
- collecting sensor data indicative of respiratory activity or a physical state of the human subject using at least an inertial measurement unit (IMU) implanted in the human subject;
- receiving the sensor data from the IMU;
- determining a position of the human subject from the sensor data;
- delivering stimulation to a nerve which innervates an upper airway muscle of the human subject using a stimulation system;
- and
- activating, using the stimulation system, the delivery of stimulation to the nerve upon a detection of a transition in the position of the human subject.
A implantable system for treating obstructive sleep apnea (OSA) in a human subject, comprising:
- one or more sensors, wherein each sensor is configured to collect sensor data indicative of respiratory activity or a physical state of the human subject when placed on, in proximity to, or implanted in, the human subject;
- and
- a controller communicatively linked to the one or more sensors and configured to;
- receive the sensor data from the one or more sensors,
- determine one or more respiratory parameters for the human subject, using the sensor data,
- calculate a standard deviation or a variance of the one or more respiratory parameters over a trailing window comprising 75-120 time points or a time range of 5-8 minutes, and
- classify the human subject as being awake or asleep by comparing the calculated standard deviation or a variance against a predetermined threshold;
- and
- a stimulation system, communicatively linked to the controller and configured to deliver stimulation to a nerve which innervates an upper airway muscle of the human subject based on the classification by the controller, wherein the controller is configured to cause the stimulation system to activate the delivery of stimulation to the nerve when the controller detects a transition in the position of the human subject.
