A novel measure of cardiopulmonary coupling during sleep based on the synchrosqueezing transform algorithm.
Yining Wang; Wenbin Shi, Member, IEEE; Chien-Hung Yeh*, Senior Member, IEEE

In this paper, a novel measure for automatic sleep apnea detection is proposed by integrating the synchrosqueezing transform (SST) algorithm with the standard cardiopulmonary coupling (CPC) method. Initially, the single-lead ECG signal of individuals during sleep is collected, from which two time series are obtained, namely, the cardiac inter-beat interval (R-R) and the ECG-derived respiration (EDR) signal. Synchrosqueezing transform is then applied to these two physiologic time series to quantify cardiopulmonary dynamics, and the CPC index is further computed to construct sleep spectrograms. Features derived from such spectrogram are used as input to five machine-learning-based classifiers including decision trees, support vector machines, k-nearest neighbors, etc. By using both the simulated data and real ECGs, the feasibility and reliability of the proposed SST-CPC method in automatic respiratory event detection are validated. Furthermore, comparisons to the other two original CPC methods based on short-time Fourier transform (STFT) and continuous Wavelet transform (CWT) are also performed in this paper. The results reveal that the SST-CPC method is robust to both the noise level and signal bandwidth, outperforming Fourier-based and Wavelet-based approaches. Meanwhile, from the sleep spectrograms obtained by the SST-CPC method, it is evident to see that the occurrence of low-frequency coupling is highly consistent with the expert-labeled apnea annotations on a minute-by-minute basis. Furthermore, by integrating SST-CPC features with common-used heart rate and respiratory features, accuracies for per-minute apnea detection improve from 72% to 83%, validating the added value of SST-CPC biomarkers in sleep apnea detection. The proposed SST-CPC method enhances sleep diagnostic capabilities and may serve as a complementary tool to the routine diagnosis of sleep respiratory events.
