Most electronic sphygmomanometers use the oscillometric method to measure blood pressure. Blood pressure measurement by oscillometric method is to determine blood pressure by establishing the relationship between systolic blood pressure, diastolic blood pressure, mean pressure and cuff pressure shock wave.
The acquisition of this algorithm is mostly based on statistical analysis of data obtained from large-scale population measurements, and the algorithms of different manufacturers are not uniform.
Therefore, when the same patient uses different brands of electronic sphygmomanometers, the measured values will be different. different.
The electronic sphygmomanometer uses the oscillometric method, an algorithm based on statistical laws, to calculate blood pressure values. Therefore, for individuals whose blood pressure variation laws are close to the statistical laws, the measurement results are relatively accurate; for individuals whose blood pressure changes are significantly different from the statistical laws Individuals with differences will have larger deviations in the measurement results.
Therefore, the disadvantage of the electronic sphygmomanometer is that it is not suitable for some special individuals, and the advantage is that the patient can complete the blood pressure measurement independently, and the operation is simple and suitable for the elderly.
