Sleep-disordered breathing (SDB), including obstructive sleep apnea (OSA), is a common disoder in childhood. Polysomnography (PSG) sleep studies are the gold standard for the diagnosis and classification of sererity of OSA determining sleep quality and arousals based on electroencephalography (EEG). PSG-studies are complex and expensive and this study assesses sleep quality and sleep stability according to the severity of SDB in children by using ECG-based CPC-analysis.
Estimating correlation between CPC values and arousal index demonstrates that the arousal index is negatively correlated with HFC (r=-0.466, P<0.001), positively correlated with LFC (r=0.543, P<0.001) and eLFCBB (r= 0.460, P < 0.001).
The CPC parameters reflect sleep fragmentation and severity of OSA as well as PSG parameters in children. Thus, sleep stability can conveniently be measured in pediatric OSA patients using CPC analysis.
