summary

Generally, the elderly or people with high blood pressure at home have to prepare a sphygmomanometer to facilitate the measurement of blood pressure at any time. But now there are many kinds of sphygmomanometers, so it is difficult to choose. Let's share with you which kind of sphygmomanometer can measure accurately.

Which kind of sphygmomanometer can measure accurately

In fact, most people may have been exposed to these two kinds of sphygmomanometers, namely mercury and electronic sphygmomanometers. When we went to the hospital to see a doctor, we saw that all the sphygmomanometers used in the hospital were mercury. This is because the amount of mercury is more accurate, and the hospital has to calibrate it every month, so the data obtained is more accurate. However, because the electronic sphygmomanometer cannot be calibrated, the accuracy is poor .

Mercury sphygmomanometer usually uses stethoscope to measure diastolic blood pressure and systolic blood pressure according to the presence or absence of sound, so many people think it's troublesome, and they certainly can't learn it. But if you can touch it a little, it's still relatively simple, especially for patients with high blood pressure, because it's to measure arm blood pressure, so this kind of sphygmomanometer is more accurate.

Now many people have seen the electronic sphygmomanometer, the main feature of this sphygmomanometer is simple operation, easy to use, so by many people like. It only needs to be tied to the wrist or the arm to read by itself. If it is a normal person to measure the blood pressure, anything can be done. But for patients with long-term hypertension, the peripheral vascular sclerosis is serious, so the one tied to the wrist is not so accurate. It is more reliable to choose the one tied to the arm.
