Physiological parameter monitoring device and method

A physiological parameter monitoring device, comprising:

• a front-end circuit configured to acquire a first physiological signal with a detection anomaly corresponding to a first physiological parameter of a patient from a signal output by a first sensor and a second physiological signal without a detection anomaly corresponding to a second physiological parameter of the patient output by a second sensor, wherein the first physiological signal and the second physiological signal are homologous signals, the homologous signals being signals derived from a vital activity of a same organ;
• a processor configured to receive the first physiological signal and the second physiological signal, and obtain at least part of a first analysis result of the first physiological parameter at least partially based on the second physiological signal;
• and
• an output component configured to receive the analysis result output by the processor, and output the analysis result in a perceivable manner.
