The bottom of the cuff should be 1 to 2 cm above the elbow of the arm
The cuff wear is not the same as the measurement results different times
Mercury sphygmomanometers require that the user must have professional training and use it in conjunction with a stethoscope. Therefore, it is not very convenient for the family. In some cases, measurement results are inaccurate due to improper use of the patient.
For example, some people do not know the correct place to wear a sphygmomanometer cuff, so the results of measuring blood pressure are different. In fact, whether it is a mercury sphygmomanometer or an electronic sphygmomanometer, the bottom of the cuff should be 1 to 2 cm above the elbow of the arm. Some patients wear the cuff too high or too low and the pressure has changed when these blood flows through these places. The result of the measurement is certainly not accurate.
In addition, some electronic sphygmomanometer cuffs range from 22 to 32 cm, but some users have arm circumferences that are larger or smaller than the applicable range of the cuff. As a result, blood pressure measurements may not be accurate. Therefore, you must configure a properly sized cuff and wear it in the correct position.
On the other hand, it is also important to set a time for measuring blood pressure every day. Some people measure blood pressure. Today is an early morning wake-up test, and tomorrow it is measured at noon. You know, people's blood pressure changes within a day is relatively great. Strictly speaking, people's blood pressure at each moment is not the same, and it will change with changes in people's psychological state, time, season, temperature, and the location and position of the measurement. Therefore, the time for measuring blood pressure every day should be fixed. Doctors recommend that the best time to measure blood pressure should be after getting up early in the morning when the person is in a resting state and can truly reflect the blood pressure level.
