Evaluate the feasibility of automatic sleep staging, microarousal detection, and sleep apnea recognition using heart rate variability and respiratory signals recorded via smart wearable devices.
Analyzed heart rate variability (HRV) and respiratory signals in the frequency domain using spectral and cross-spectral statistical parameters.
Compared automated signal classification performance directly against standard clinical polysomnography (PSG).
Demonstrated an 89.9% classification accuracy in distinguishing rapid eye movement (REM) from non-REM sleep.
Achieved an 88% accuracy for automatic detection of sleep apnea events.
Identified microarousals based on characteristic transient variations in the HRV signal.
