The best sphygmomanometer

summary

With the promotion of self-test blood pressure technology, more and more people are willing to self-test blood pressure. In order to improve the accuracy of measurement, it is important to choose a suitable sphygmomanometer. However, there are many kinds of sphygmomanometers in the market. So, what kind of sphygmomanometer is the best, which kind of sphygmomanometer can measure accurately?

The best sphygmomanometer

First: auscultation measurement principle is the only recognized blood pressure measurement principle in medical field. At present, there are medical mercury sphygmomanometer and automatic sphygmomanometer based on auscultation. These two types of sphygmomanometers are currently used in many medical institutions. The Thai auscultation method automatic sphygmomanometer measures blood pressure because of its automatic pressure and deflation operation. It is also the best choice for home sphygmomanometer. Well explained what kind of sphygmomanometer is best, which kind of sphygmomanometer can measure accurately.

Second: close the valve on the balloon, and the surveyor's line of sight should be at the same level as the scale on the mercury column to observe the height of the mercury column. After the pulse of the radial artery disappears, pressurize 4 kPa (30 mmHg) to stop the inflation. Slightly open the air valve to make the mercury drop slowly. When the first pulse is heard, it is "high pressure", that is, systolic pressure. Continue to slightly deflate, mercury slowly drops to a certain scale on the mercury column, when the sound suddenly becomes weak or disappears, it is "low pressure", that is, diastolic pressure.

Third: after the first measurement, the blood pressure should be completely deflated. After at least one minute, repeat the measurement again, and take the average value of the two times as the obtained blood pressure value. In addition, if you want to determine whether you have high blood pressure, it's best to measure it at different times. It's generally believed that you can determine high blood pressure only if you have at least three occasionally measured blood pressure values on different days.

matters needing attention

Compared with mercury sphygmomanometer, automatic pressure deflation, digital display measurement results. In the same use of auscultation measurement principle can ensure the accurate measurement of blood pressure, the operation is simpler, one key operation directly displays the results, more suitable for home blood pressure measurement.
