With the improvement of people's living standards, our pursuit of health is becoming higher and higher. For example, more and more people pay more  attention to their blood pressure. With the progress of science and technology, we have more and more ways to obtain our blood pressure value. There are a variety of blood pressure monitor in the market, how to choose to buy?

Why is the blood pressure not accurately measured?

The main principle of our daily blood pressure measurement is to pressurize the air, compress the local artery and block its blood flow fluctuation, and then release the pressure to restore the blood flow fluctuation. In this process, the blood flow pressure is measured and determines that when measuring blood pressure, the stronger the blood vessel fluctuation, the thicker the blood vessel, the closer to the heart, the more accurate the pressure can be measured. However, the blood vessels at the wrist do not fluctuate strongly and are far away from the heart, which means it may have situation of inaccuracy of wrist blood pressure measurement. If it is non-pressure-blocking blood pressure perception, the measured blood pressure may have a greater error.

Which sphygmomanometer is the best?

The BP monitor we often use include mercury blood pressure monitor, arm electronic blood pressure monitor and wrist digital blood pressure monitor. Which one is the most accurate?

1. Mercury blood pressure monitor:

The use of mercury blood pressure monitor needs training, and it is inconvenient to carry, also will have more or less errors measurement result if used incorrectly . Now it has been gradually replaced by electronic digital blood pressure monitor. Moreover, the mercury blood pressure monitor is not practical as a household blood pressure measurement.

2. Arm electronic blood pressure monitor:

The measured part of digital upper arm blood pressure monitor is same as the mercury blood pressure monitor, which is the main artery of the upper arm and the value is more accurate. Anyone can complete the operation without crowd restrictions. In the current hypertension guidelines, the digital arm sphygmomanometer has been taken as the first choice for measuring blood pressure.

3. Wrist electronic blood pressure monitor:

The wrist blood pressure monitor: is small size and portable. It is more suitable for people without hypertension to monitor blood pressure, especially for young and middle-aged people without blood circulation disorders. After all, it is convenient to operate on the wrist. However, its accuracy needs to be improved and should not be used as blood pressure monitoring for hypertensive people.
