Spectral features dominate sleep apnea detection in BCG signals

By PulseAugur Editorial · [1 sources] ·

Researchers have identified that spectral features, particularly those in the breathing frequency band (0.1-0.4 Hz), are the most effective for detecting respiratory events in sleep apnea patients using ballistocardiography (BCG) signals. A large-scale, patient-independent comparison of ten BCG feature groups revealed that frequency-domain features accounted for a significant portion of the discriminative information. Machine learning models like Random Forest and Histogram Gradient Boosting achieved high performance (AUC-ROC of 0.967-0.969) using these features, suggesting a more focused approach for future BCG-based sleep apnea monitoring systems.

    Spectral Features Dominate BCG Respiratory-Event Detection: A Large-Scale Patient-Independent Comparison of Feature Groups in Sleep Apnea Patients

    arXiv:2608.28242v1 Announce Type: new Abstract: Unobtrusive ballistocardiographic (BCG) sensing is a promising modality for long-term sleep-apnea monitoring, yet it remains unclear which signal features are most discriminative for respiratory-event detection. We present a literat…
