| [en] This paper proposes a novel method for the scoring
of sleep apneas and hypopneas (SAHs) based on the recording and the analysis of the midsagittal jaw movements. Continuous wavelet transform was used to delineate events which were likely to contain the SAHs, while hidden markov models (HMMs) classified events. Considering 28 recordings from which awakenings were discarded, the method detected SAHs with a sensitivity and a specificity of 82.2% and 78.3% respectively. Obstructive, central and mixed respiratory events were distinguished fairly accurately. The jaw motion is hence a reliable marker of respiratory efforts and may suffice by itself to score SAHs. | |
