Résumé
This work aims at studying the usefulness of
the spectral information contained in airflow (AF) recordings
in the context of Obstructive Sleep Apnea-Hypopnea
Syndrome (OSAHS) in children. To achieve this goal, we
defined two spectral bands of interest related to the
occurrence of apneas and hypopneas. We characterized these
bands by extracting six common spectral features from each
one. Two out of the 12 features reached higher diagnostic
ability than the 3% oxygen desaturation index (ODI3), a
clinical parameter commonly used as screener for OSAHS.
Additionally, the stepwise logistic regression (SLR) featureselection
algorithm showed that the information contained in
the two bands was complementary, both between them and
with ODI3. Finally, the logistic regression method involving
spectral features from the two bands, as well as ODI3,
achieved high diagnostic performance after a bootstrap
validation procedure (84.6±9.6 sensitivity, 87.2±9.1
specificity, 85.8±5.2 accuracy, and 0.969±0.03 area under
ROC curve). These results suggest that the spectral
information from AF is helpful to detect OSAHS in children
