Abstract
A computer-implemented method for a monitoring device being executed by a processor of the monitoring device comprises acquiring at least two kinds of physiological signals via a sensor of the monitoring device, obtaining a signal quality index of each of the at least two kinds of physiological signals by the processor of the monitoring device, providing a homologous physiological parameter value corresponding to each of the at least two kinds of physiological signals by the processor of the monitoring device, and fusing the homologous physiological parameter values based on the signal quality index of each of the at least two kinds of physiological signals and providing a fused value of the homologous physiological parameter values by the processor of the monitoring device. The disclosed physiological parameter processing method avoids disadvantages caused by relying on a single physiological signal.
