Abstract:
1. A method of calculating a blood pressure using a memory to store a plurality of calculation methods, comprising: providing a non-invasive blood pressure measurement apparatus which includes a cuff, a determiner, a decider and the memory, the cuff being inflatable and deflatable and adapted to be fitted on a part of a living body and in which a plurality of calculation methods each of which has priority in accordance with a type of noise information are set; detecting, by a detector included in the cuff, a signal waveform representing a change in an oscillation amplitude and a change in a cuff pressure; determining through the determiner the type of the noise information contained in the detected signal waveform; determining through the determiner a priority status from highest priority to lowest priority for each of the calculation methods based on the determining of the type of the noise information contained in the detected signal waveform; deciding through the decider the blood pressure from at least one candidate value for the blood pressure, which is calculated by one of the calculation methods stored on the memory that has the highest priority status with respect to the determined type of the noise information; and displaying the decided blood pressure.
