BACKGROUND: Continuous positive airway pressure (CPAP) therapy is recommended for moderate-to-severe obstructive sleep apnea (OSA). We aimed to investigate whether or not combining drug-induced sleep endoscopy (DISE) with CPAP titration may inform more appropriate pressure settings.
MATERIALS AND METHODS: A sleep CPAP titration study and DISE-CPAP treatment were performed on consecutive subjects with moderate-to-severe OSA under controlled sedation using bispectral monitoring. Video recordings of dynamic changes in UA with CPAP pressure ranges of 5 to 25 cm were assessed in accordance with the VOTE classification. The 95th percentile (95th PC) pressure of the CPAP titration trial was compared to optimal pressure for alleviating UA blockage.
RESULTS: We included 30 subjects (mean age 37.5, 17% women). All showed UA collapse at more than one level, with more than 80% of them collapsing completely at the levels of the velum and oropharynx. At the velum, 90% of subjects experienced improvement with CPAP. At the oropharynx, 75% of subjects experienced improvement with CPAP. The mean pressure and standard deviation (SD) of the 95th PC of the CPAP titration was 14.3 (3.5) cmH2O, while the pressure required to partially or fully open the airway (best possible pressure) was 16.1 (3.9) cmH2O; mean (SD) difference, 1.9 (2.2); P ≤ 0.001. The limits of agreement between the CPAP 95th pressure and the ideal pressure were - 6.32 to + 2.52.
CONCLUSIONS: The palate and lateral pharynx were more affected by CPAP than the hypopharynx. Most of the time, the mean 95th PC CPAP titration pressure was lower than the mean optimal pressure needed to alleviate the collapse.
