Electronic sphygmomanometer has become a necessity for many familiesCompared with the traditional mercury sphygmomanometer, the electronic sphygmomanometer is more convenient to use and more direct to read values. But many people find that the value measured by the electronic sphygmomanometer after being used for a long time will not be so accurate. In serious cases, it is easy to give wrong guidance on medication, and they do not know how to deal with it. Is it possible that the electronic sphygmomanometer can only be replaced if it is inaccurate? Today, let's solve the problem of accuracy of electronic sphygmomanometer.
The inaccurate blood pressure measurement of electronic sphygmomanometer is mainly due to its own reasons and interference factors of sphygmomanometer.
oneMeasuring blood pressure is a fixed behavior, but the blood pressure will fluctuate from time to time, and the electronic sphygmomanometer is very sensitive, so each time you measure blood pressure, you may get different data. Many people think that the sphygmomanometer is inaccurate.
twoThere are issues with the method and timing of measuring blood pressure. People's blood pressure varies after excitement, nervousness, exercise, drinking alcohol, and smoking. If we measure blood pressure at this time, the results will definitely be significantly different from the usual measurement results. There are more people who use improper methods that affect the accuracy of blood pressure measurements.
threeLong term use:As electronic sphygmomanometer has become a necessity of the family, it has been used for a long time with high frequency, the chip is outdated and aging, the battery voltage is insufficient, the cuff deformation and other problems occur, which are also the main reasons for the inaccurate measurement of sphygmomanometer.
No matter whether the measurement is accurate or not, it's better to take a measurement
If we often use electronic sphygmomanometer at home, we recommend two better methods to help people judge whether it is accurate and can work normally:
oneThe simplest way is to take the sphygmomanometer to the hospital and compare it with the blood pressure measured by the sphygmomanometer. The difference is not more than5mmHgIt means that the accuracy of this electronic sphygmomanometer is guaranteed, and the difference can exceed5mmHg, then there are some problems with the accuracy of the sphygmomanometer.
twoIf you have both a mercury sphygmomanometer and an electronic sphygmomanometer at home, you can use a mercury sphygmomanometer to help judge.
The electronic sphygmomanometer measures the first blood pressure,twoMinutes later, use a mercury sphygmomanometer to measure the blood pressure for the second time, and thentwoThe third blood pressure was measured with an electronic sphygmomanometer in minutes. Take the average of the first and third measurement results and compare them with the second measurement, and the difference does not exceed5mmHg, indicating that the accuracy of the electronic sphygmomanometer is guaranteed, and the difference exceeds5mmHg, then the accuracy of the sphygmomanometer is problematic.
Three Practical Calibration Methods of sphygmomanometer
Once we find that our electronic sphygmomanometer is inaccurate in blood pressure detection, we must calibrate it in time and find the Bureau of Quality and Technical Supervision
The institutions providing sphygmomanometer calibration services are different in different regions. Generally speaking, the Quality Supervision Bureau has a testing agency that can conduct calibration. Citizens can consult with the local Quality Supervision Bureau and find relevant departments for calibration.
Some brands of sphygmomanometer have after-sales service in different regions. If you find that the electronic sphygmomanometer is inaccurate, you can contact after-sales for calibration. If you buy at a pharmacy, you can go directly to the pharmacy for calibration.
go to the hospital
Generally speaking, the measurement results of the sphygmomanometer in the hospital are reliable and accurate. Because the sphygmomanometer in the public hospital is checked every year, we might as well take the commonly used electronic sphygmomanometer at home and use the sphygmomanometer in the hospital to help with calibration.
