Cardiac gating technique for arterial oxygen saturation measurement

We have proposed a multi-stage motion-tolerant algorithm for reliable extraction of oxygen saturation. We introduce a novel cardiac gating algorithm to suppress effects of motion artifacts caused by venous blood movement on wearable oximetry sensors. This approach eliminates the motion artifact effectively and results in a much more accurate and reliable oxygen saturation readings compared to traditional measurement techniques. The proposed approach is tested and validated with real-world data captured using forehead and finger sensors from multiple subjects.
