Abstract: Disclosed are methods, apparatuses, and systems for performing physiological parameter signal fusion. By respectively analyzing a plurality of input physiological parameter signals, and obtaining a feature of each physiological parameter signal; according to the feature of each physiological parameter signal, obtaining and outputting a fusion state of the plurality of the physiological parameter signals; if the fusion state is a fusion of the at least two physiological parameter signals with the first physiological parameter signal is dominant, highlighting the first physiological parameter signal; and if the fusion state is a fusion of the at least two physiological parameter signals with the second physiological parameter signal is dominant, highlighting the second physiological parameter signal.

Abstract: One variation of a method for identifying homology of physiological signals comprises: receiving signal data of two different types of physiological signals; performing waveform matching on the signal data of the two different types of physiological signals to determine waveform matching information in the signal data of the two types of physiological signals; calculating an associative feature between the signal data of the two different types of physiological signals according to the waveform matching information; calculating a homology reference coefficient corresponding to the two different types of physiological signals according to the associative feature; and determining that the two different types of physiological signals are homologous when the homology reference coefficient is greater than a preset value.

Abstract: A liquid reactivity detection device and method. The liquid reactivity detection device includes: a breathing signal acquisition module, a hemodynamic signal acquisition module and a liquid reactivity detection module. The breathing signal acquisition module and the hemodynamic signal acquisition module work in cases where the subject is in any one of the following breathing modes: a spontaneous breathing mode, a spontaneous breathing combined with mechanical ventilation mode, and a mechanical ventilation mode. The hemodynamic signal acquisition module is configured to acquire at least one hemodynamic signal of the subject. The breathing signal acquisition module is configured to acquire at least one breathing signal of the subject. The liquid reactivity detection module is configured to determine the liquid reactivity of the subject according to the breathing signal and the hemodynamic signal.
