Although this kind of sphygmomanometer is easy to operate and carry, people often have different measurement results. Is the electronic sphygmomanometer accurate or not?
The use of electronic sphygmomanometer is a trend, and the problem of inaccurate measurement is also affected by many factors. In order to measure accurately, we need to pay attention to the following questions.
1. Regular channel purchase
To buy electronic sphygmomanometers, you should buy regular brands through regular channels, and you can't just buy some brand-name sphygmomanometers.
calibrate
Electronic sphygmomanometers need to be calibrated before use, and most electronic sphygmomanometers are calibrated in advance when they leave the factory. However, it is recommended to calibrate them again before use, which can be compared with desktop mercury sphygmomanometer. The range of pressure difference is
3. Four settings: fixed time, fixed position, fixed position and fixed sphygmomanometer.
Long-term use of electronic sphygmomanometer requires setting time, measuring position and posture, and paying attention to fixing measuring instruments. It is suggested to monitor blood pressure in the morning, peak blood pressure, blood pressure before going to bed and blood pressure before taking medicine every day. Measure your hands for the first time, and then fix the hand with higher blood pressure. Measure in a fixed sitting or lying position, and try to relax before measuring.
It is very demanding to use electronic sphygmomanometer to measure the environment. It is necessary to keep the environment quiet. During the measurement, the subjects should not talk or engage in strenuous activities. It is best to sit still for 5 minutes before starting the measurement. Before the measurement, they should not smoke, drink or ingest other irritating foods or drinks. Empty your bladder and take more deep breaths. It is not recommended to measure blood pressure within one hour after eating.
If the blood pressure fluctuates from time to time, there is no guarantee that the blood pressure value will be exactly the same every time, but under normal circumstances, the difference will not be too great. It is recommended to measure the average value several times, but don't measure the next time immediately after one measurement, which will compress the blood vessels. You can rest for ten minutes before starting the next measurement and make records.
The electronic sphygmomanometer needs to be properly kept. If there is humidity or power shortage, the measurement results will also be biased.
Finally, I would like to remind you that the electronic sphygmomanometer is only used for daily monitoring and cannot be used as a diagnostic tool. If the blood pressure is abnormal, it is recommended to seek medical advice in time, and the treatment plan should not be changed at will according to your own test results.
