Presently, there are limited reliable screening tests for both central (CE) and obstructive (OE) respiratory events. This study compared three indices, derived from pulse oximetry and electrocardiogram (ECG), with the PSG gold standard. These indices were heart rate (HR) variability, arterial blood oxygen de- saturation (SaO2) and pulse transit time (PTT). Methods: 15 children (12 male) from routine PSG studies were recruited (aged 3- 14 years). The characteristics of the three indices were based on known criteria for respiratory events (RPE). Their estimation singly and in combination was evaluated with simultaneous scored PSG recordings. Results: 215 RPE and 215 tidal breathing events were analysed. For OE, the obtained sensitivity was HR (0.703), SaO2 (0.047), PTT (0.750), considering all three indices (0) and either of the indices (0.828) while specificity was (0.891), (0.938), (0.922), (0.953) and (0.859)- respectively. For CE, the sensitivity was HR (0.715), SaO2 (0.278), PTT (0.662), considering all indices (0.040) and either of the indices (0.868) while specificity was (0.815), (0.954), (0.901), (0.960) and (0.762) accordingly. Conclusions: Preliminary findings herein suggest that the later combination of these non- invasive indices to be a promising screening method of SDB in children.展开更多
