(a) and (b): example of a breathing profile with obstructive apnea events marked in orange shade. The polygraph nasal airflow () and bench simulation airflow () are respectively showed in (a) and (b) with blue curves. The red curve in (b) represents the estimated non-obstructed nasal airflow (), issuing from a central ventilation command. (c) and (d): example of a breathing profile without disordered breathing events. The and are respectively showed in (c) and (d) with blue curves. The magenta points in all graphs represent the breath onsets.
