Sleep apnea treatment apparatus
First Claim
1. A system for delivering pressurized gas to an airway of a patient comprising:
- a pressure generating system;
a conduit having a first end operatively coupled to the pressure generating and a second end;
a patient interface operatively coupled to the second end of the conduit;
a sensor operatively coupled to the pressure generating system, the conduit, or the patient interface, wherein the sensor is adapted to detect a parameter indicative of a patient breathing into the patient interface; and
a processor operatively coupled to the sensor and the pressure generating system, wherein the processor determines whether a patient is breathing into the patient interface based on the output of the sensor, wherein the processor is programmed to activate the pressure generating system from a first state, in which the pressure generating system is deactivated, to a second state, in which the pressure generating system is activated and operated in accordance with a pressure support mode over multiple respiratory cycles, responsive a determination that such a patient is breathing into the patient interface.

Abstract
Improved methodology and apparatus for the clinical study and treatment of sleep apnea which incorporates one or more of the following features: (1) application of mono-level, alternating high and low level, or variable positive airway pressure generally within the airway of the patient with the mono-level, high and low level, or variable airway pressure generally being coordinated with and/or responsive to the spontaneous respiration of the patient, (2) usage of adjustably programmable pressure ramp circuitry capable of producing multiple pressure ramp cycles of predetermined duration and pattern whereby the ramp cycles may be customized to accommodate the specific needs of an individual sleep apnea patient so as to ease the patient'"'"'s transition from wakefulness to sleep, (3) remote control or patient-sensed operation of the apparatus, (4) employment of safety circuitry, reset circuitry and minimum system leak assurance circuitry, controls and methods, and (5) utilization of clinical control circuitry whereby sleep disorder data may be compiled and appropriate therapy implemented during a one-night sleep study.
