  • Publication number: 20220096018
    Abstract: A physiological parameter calculation device includes an acquiring section, a failure sensing section and a calculation section. The acquiring section acquires a plurality of signals corresponding to physiological information of a subject. The failure sensing section senses a failure of the plurality of elements. The calculation section calculates a physiological parameter based on the plurality of signals acquired by the acquiring section and a first algorithm or a second algorithm. The calculation section calculates the physiological parameter: based on the first algorithm when the failure sensing section does not sense a failure in an element for acquiring a signal used for the first algorithm among the plurality of elements, and based on the second algorithm when the failure sensing senses that a failure occurs in an element for acquiring a signal used for the first algorithm among the plurality of elements.
