The introduction of CPAP had immediate benefits, including the normalization of the apnea\u2013hypopnea index and a resolution of stridor in more than two\u2010thirds of the cases, decreased arousal index, and increased rapid eye movement sleep. CPAP therapy was well tolerated, and only two patients had emergent central apneas.
