摘要： A blood pressure measuring apparatus includes a pressure control unit that controls an applied pressure applied to a region of a living body in which a vein and artery exist by a cuff mountable to the region, a detection unit that detects pressure waveforms in which pulse wave components from the region overlap with the applied pressure, and an analysis unit that obtains a respiratory variation on the waveform of artery and a venous pressure based on the pressure waveforms detected by the detection unit through one-time blood pressure measurement. The analysis unit obtains the respiratory variation on the waveform of artery based on data of a first pressure waveform in a first process, and the venous pressure based on data of a second pressure waveform in a second process and the data of the first pressure waveform.

摘要： A medical photometer includes a processor and a memory that stores an instruction readable by a computer. When the instruction is executed by the processor, the medical photometer acquires an intensity of one of a first intensity signal and a second intensity signal, the first intensity signal corresponding to an intensity of a first light beam that has a first wavelength and that is transmitted through or reflected from a tissue of a living body, and a second intensity signal corresponding to an intensity of a second light beam that has a second wavelength and that is transmitted through or reflected from the tissue of the living body acquires an intensity ratio of the first intensity signal and the second intensity signal, and detects an artifact of the living body based on the acquired intensity and the acquired intensity ratio.
