SpO$_2$ Predictor-Guided Stage-Wise Time-Frequency Reconstruction of Low-Quality Dual-Wavelength PPG for Oxygen Saturation Estimation
arXiv:2607.07996v1 Announce Type: cross Abstract: Continuous oxygen saturation (SpO$_2$) estimation from wearable photoplethysmography (PPG) is important for long-term health monitoring, but low-quality red and infrared PPG segments can distort waveform morphology and degrade SpO$_2$ prediction accuracy. Existing PPG denoising and reconstruction methods usually optimize waveform fidelity or heart rate characteristics, while time-domain waveform loss on PPG signals alone insufficiently preserves frequency structure and SpO$_2$-relevant information. This paper proposes a SpO$_2$ predictor-guided
The continuous drive for more accurate and reliable health monitoring via wearables is leading to advanced signal processing techniques, especially as AI/ML capabilities improve.
Improved accuracy in SpO2 estimation from low-quality PPG signals enhances the reliability of long-term health monitoring, crucial for early detection and management of various conditions.
This advancement makes wearable health monitoring more robust and less susceptible to environmental or user-induced noise, potentially expanding its applicability and trust.
