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.

[ What is claimed is:] [1.]1. Method for adaptively providing continuous positive airway pressure in an upper airway system comprising the steps of:detecting airflow in the upper airway system in predetermined increments of time;averaging said airflow information over a second period of time;distinguishing respiratory and non-respiratory components of said airflow using said averaged information;identifying periods of inspiration and expiration using said non-respiratory flow information;extracting features of said upper airway system during at least one of said periods of inspiration;identifying airflow profiles based on said detected airflow and said extracted features;determining a critical pressure which produces a first predetermined airflow profile;introducing incremental pressure increases to determine a second pressure, greater than said first critical pressure, which produces a second predetermined airflow profile; andsetting pressure in said upper airway system using said second pressure.
