Understanding the Features and Usage of an Electronic Blood Pressure Monitor
 By dividing the measurement sites, home electronic blood pressure meters can be classified asThe two major categories are wristband and armband.。The accuracy of arm cuff blood pressure measurement on the upper arm has been officially confirmed.It can be treated in the same way as a standard mercury column blood pressure meter. Moreover, its use is relatively simple, and it will not produce errors due to improper methods. However, when measuring, one should remove the sleeve, and there should not be too much clothing between the arm and the blood pressure meter. In addition, if the cuff is tied too tightly or too loosely, it will affect the measured value. Generally, after the cuff is inflated and can accommodate a finger gap, it is better.
 Wrist cuff blood pressure monitors are more convenient than arm cuff ones.However, its use is quite precise. Firstly, one must pay attention to the wrist position when measuring blood pressure. If you are sitting, the wrist should be placed at the level of the heart, roughly at the level of the nipple; if you are lying down, the wrist should be placed by the side of the bed, and the measured pressure will be slightly higher, as this position is lower than the heart level by about4.4Centimeters. Furthermore, the position of the palm also has an impact on blood pressure. When the palm is bent towards the palm, the blood pressure is higher; however, if it is bent towards the back, the blood pressure can be lower than when the palm is straight.
 Therefore, if you need to repeat the measurement, make sure to do it under the same conditions. This includes maintaining the same posture (sitting or lying down), the position of your wrist, and the position of your palm. The position of the wristband should also not be moved. Moreover, the repeat measurement should be at least separated by2Minutes, and before measuring, exhaust all the air from the airbag.
 Compared with blood pressure monitors with wrist and arm cuffs, the readings may not always be the same, and it is generally recommended to take the average value.To understand your personal condition, you can compare the wrist blood pressure monitor with the standard mercury column blood pressure monitor. Place them on your left and right hands, and have the doctor measure them simultaneously to see the difference. Since there is a slight difference in blood pressure between the left and right hands, you can exchange the blood pressure monitors and measure them again. Take the average of the two measurements.
 Some people have higher blood viscosity and poor microcirculation (such as diabetics and those with arteriosclerosis), so these individuals should not use wrist bands; if they do, they need to understand the difference in the measured values between wrist bands and arm bands.
