ABSTRACT
OBJECTIVE:
While out-of-center testing was introduced as an alternative for the diagnosis of obstructive sleep apnea in adults, polysomnography (PSG) is still considered mandatory in the diagnosis of sleep-disordered breathing (SDB) in children. The purpose of this study was to validate the outpatient screening device ApneaLink® in comparison to PSG in children and adolescents for the diagnosis of SDB.METHODS:
Sixty consecutive children and adolescents (10.4 ± 6.2, 0-22 years) with suspected SDB admitted to the sleep laboratory underwent simultaneous recording with full PSG and the screening device ApneaLink® based on flow measurement and oxygen saturation.RESULTS:
The mean apnea-hypopnea index (AHI) was 11.8 ± 19.7 in PSG and 10.3 ± 12.0 in ApneaLink®. When the AHI threshold was set to 5/h to diagnose SDB, the overall sensitivity for ApneaLink® was 79% and the specificity was 63%. After reducing the AHI threshold to 1/h, the sensitivity and specificity were 94% and 29%. In children older than 10 years, the performance of ApneaLink® improved (AHI 5/h sensitivity 80%, specificity 64%; AHI 1/h sensitivity 100%, specificity 50%).CONCLUSION:
These results show that the outpatient screening device ApneaLink® reliably identifies SDB in preselected children older than 10 years. In contrast, it may not be used for the exclusion of SDB.Key words
