Abstract
The present invention relates to systems and methods for automatically and continuously regulating the level of nasal pressure to an optimal value during OSA treatment. OSA therapy is implemented by a device which automatically re-evaluates an applied pressure and continually searches for a minimum pressure required to adequately distend a patient's pharyngeal airway. For example, this optimal level varies with body position and stage of sleep throughout the night. In addition, this level varies depending upon the patient's body weight and whether or not alcohol or sleeping medicine has been ingested.
Claims8
System for providing continuous positive airway pressure in an upper airway system comprising:
- means for detecting airflow in an upper airway system of a patient;
- means for generating pressure in said upper airway system in response to a command pressure;
- and
- means for adaptively controlling said pressure generating means in response to said detecting means to automatically provide continuous positive airway pressure, said adaptive control means introducing incremental pressure perturbations for setting a command pressure relative to a predetermined critical pressure.
A system for providing continuous positive airway pressure in an upper airway system comprising a detector adapted to detect airflow in an upper airway system of a patient;
- an air pressure generating unit adapted to generate pressure in the upper airway system;
- and
- a processor adapted to adaptively control the air pressure generating unit, the processor adapted to control the detector to automatically provide continuous positive airway pressure, the processor controlling the air pressure generating unit to introduce incremental pressure pertubations for setting a mask pressure relative to a predetermined critical pressure.
