- Abstract
Abstract Nasal continuous positive airway pressure (CPAP) is the treatment of choice in severe obstructive sleep-disordered breathing (SDB). Partial obstruction is usually considered as mild SDB with poor CPAP adherence. In a retrospective study, we investigated the occurrence of partial obstruction in 233 age and BMI-matched male–female pairs and its impact on CPAP adherence after one year using static-charge-sensitive bed. Women had less SDB compared with men (21.8 vs 31.7% of time in bed (TIB), p p p = 0.174). In women, partial obstruction accounted for 50.2% of breathing abnormalities, in men 37.2% (p 5% of TIB) or periodic breathing, there were no differences in women’s CPAP adherence (p = 0.130 and p = 0.148, respectively). Men with periodic breathing over 5% of TIB tended to be more adherent to CPAP, (p = 0.052). The high occurrence of partial obstruction in both genders and particularly in women suggests that the apnea–hypopnea index underestimates the occurrence of SDB. There are no concerns of low adherence when treating symptomatic partial obstruction during sleep. Partial obstruction may not represent mild SDB but a different entity.
