新的PCHS框架改进了从腕部PPG估算心率的准确性

研究人员开发了一个名为物理约束谐波分离(PCHS)的新框架,以提高从腕戴式光电容积脉搏波(PPG)信号估算心率(HR)和呼吸率(RR)的准确性。该方法利用加速度计数据来指导生理信号与噪声的分离,从而解决了运动伪影的挑战。PCHS框架将PPG信号分解为其组成生理成分和一个运动相关残差,从而实现更可靠的生命体征恢复。在PPG-DaLiA数据集上的实验表明,PCHS的性能显著优于现有方法,并提供了可解释的信号分解。 AI

    Physically-Constrained Harmonic Separation for Robust Heart and Respiratory Rate Estimation from Wrist Photoplethysmography

    Wrist-worn photoplethysmography (PPG) enables continuous monitoring of cardiopulmonary physiology, but reliable heart rate (HR) and respiratory rate (RR) estimation in free-living conditions remains challenging due to non-stationary motion artifacts that spectrally overlap with p…
