Single-channel SpO2recordings from 176 children were divided into three severitygroups according to the apnea-hypopnea index (AHI): AHI<1events per hour (e/h), 1≤AHI<5 e/h, and AHI ≥5 e/h. Spectralanalysis was conducted to define and characterize a frequencyband of interest in SpO2. Then we combined the spectral datawith the 3% oxygen desaturation index (ODI3) by means of amulti-layer perceptron (MLP) neural network, in order toclassify children into one of the three OSAHS severity groups.Following our MLP multiclass approach, a diagnostic protocolwith capability to reduce the need of polysomnography tests by46% could be derived. Moreover, our proposal can be alsoevaluated, in a binary classification task for two common AHIdiagnostic cutoffs (AHI = 1 e/h and AHI= 5 e/h). Highdiagnostic ability was reached in both cases (84.7% and 85.8%accuracy, respectively) outperforming the clinical variableODI3 as well as other measures reported in recent studies.These results suggest that the information contained in SpO2could be helpful in pediatric OSAHS severity detection.
