Method and apparatus for treating hyperarousal disorders
First Claim
1. A method of control of a respiratory pressure therapy device to treat sleep disordered breathing (SDB)-comorbid hyperarousal disorders in a patient, the method comprising:
- controlling application of pressure support ventilation therapy to an airway of the patient by a respiratory pressure therapy device;
controlling the respiratory pressure therapy device to auto-titrate an expiratory positive airway pressure (EPAP) of the pressure support ventilation therapy so as to maintain airway patency of the patient, such that the EPAP is bounded below by a floor pressure limit; and
controlling, in the respiratory pressure therapy device, a determination of repeated adjustments to the floor pressure limit depending on events of interest during the auto-titration of the EPAP, wherein an adjustment to the floor pressure limit is dependent on a number of events of interest that occur in a predetermined interval during the auto-titration of the EPAP.

Abstract
Methods and apparatus provide automated controls for a respiratory pressure therapy device, such as a servo-ventilator. For example, a controller of a respiratory pressure therapy device may control application of pressure support ventilation therapy to an airway of a patient. The controller may control the respiratory pressure therapy device to auto-titrate an expiratory positive airway pressure (EPAP) of a pressure support ventilation therapy so as to maintain airway patency of the patient. The EPAP may be bounded below by a floor pressure limit. The controller may control the respiratory pressure therapy device to repeatedly adjust the floor pressure limit depending on events of interest during the auto-titration of the EPAP. Such methodologies may improve treatment for patients such as those suffering from sleep disordered breathing-comorbid hyperarousal disorders.
