新框架重构低质量 PPG 信号以准确估算 SpO2

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种新颖的框架，用于重构低质量双波长光电容积脉搏图 (PPG) 信号，这对于可穿戴健康监测中的连续血氧饱和度 (SpO2) 估算至关重要。该方法采用 SpO2 预测器来指导阶段式重构过程，结合了时域波形损失和源自短时傅里叶变换 (STFT) 的频域损失。通过将 SpO2 预测器作为约束，重构优先保留与 SpO2 相关的信息，而不是仅仅最小化波形误差。在公共和私有数据集上的实验表明，其性能优越，分别实现了最低的受试者级别平均绝对误差 (MAE) 2.882% 和 2.359%。 AI

影响 通过增强 SpO2 估算的信号质量，提高了可穿戴健康监测设备的准确性。
