Abstract
The present invention includes a method and apparatus for the optimized treatment of obstructive sleep apnea. The present invention includes a pressure source configured to provide positive airway pressure to a patient who is resting at home. The pressure source receives control signals from control electronics that define a pressure profile to be delivered to the patient. The control electronics select parameters to define the pressure profile based on factors such as a user selection, information received from a sensor, and/or a prescription.
Claims20
An apparatus for treating sleep apnea in a patient comprising:
- a pressure source configured to be coupled to a patient airway;
- a sensor configured to monitor the patient airway and generate a signal during a treatment cycle;
- an information storage device configured to store first information representing a first operating mode defining a first pressure profile including an initial pressure profile and an incident pressure profile;
- a controller configured to:
- receive a signal representing the first information;
- operate the pressure source to apply the initial pressure profile before an obstructive event;
- identify an obstructive event based upon analyzing the signal from the sensor;
- operate the pressure source to apply the incident pressure profile in response to the obstructive event;
- generate a new operating mode defining a new pressure profile based upon analyzing the signal from the sensor;
- and
- store the new operating mode in the information storage device.
