Positive airway pressure system with head position control

摘要

The invention is directed to a positive airway pressure (PAP) system with a head mounted harness assembly with a housing and a head position sensor located within or secured to the housing that detects the position of a patient's head, and communicates this head position information to a controller of the system which may be disposed within the housing having the position sensor or a second housing. The controller varies the output pressure of the pressure source e.g., a rotary compressor, based, at least in part, on the head position information provided by the head position sensor. In a preferred embodiment, the position sensor is an accelerometer.

主权项

1. A method for providing pressurized air to an airway of a patient, the method comprising the steps of:
delivering pressurized air from a pressure source to the patient's airway; sensing the patient's sleeping position with a sensor; and adjusting, using a controller, pressure of the pressurized air so that pressure delivered is at a maximum when the patient's sleeping position is a supine position and is less than the maximum when the sleeping position is a lateral position, and there is a maximum rate of pressure drop of the pressurized air delivered when the patient's sleeping position is between 30° and 60° from the supine sleeping position.
