Home self-testing of blood pressure is best done with a fully automatic electronic sphygmomanometer of the upper arm type certified by international standards.
Electronic sphygmomanometers: finger, wrist and upper arm. Finger to the arterial perception is not as good as the upper arm, and wrist-type sphygmomanometer on the measurement of the posture of the higher requirements, measured blood pressure is less accurate, more suitable for mountaineers, geological explorers, arm disability, etc. use.
The advantage of the upper arm sphygmomanometer is that the cuff compresses the brachial artery of the upper arm, and the arm where the blood pressure is measured can easily be made parallel to the right atrium (the standard posture for measuring blood pressure), which is difficult to do with the wrist type and finger type.
So, to measure blood pressure at home, it is best to use the upper arm type automatic electronic sphygmomanometer, and should be measured under emotionally stable conditions, to maintain a good habit of regular measurement.
Extended information:
Normal range of blood pressure. p>The normal range of blood pressure, the ideal blood pressure is 120/80. China's high blood pressure standard, systolic blood pressure is also known as high pressure, can not be more than 140, diastolic blood pressure is also called low pressure, can not be more than 90, which is called the normal blood pressure. If the systolic pressure exceeds 140 or the diastolic pressure exceeds 90, this can be diagnosed as hypertension.
The new U.S. standard, that systolic blood pressure exceeds 130, diastolic blood pressure exceeds 85, can be said to be high blood pressure. That's a pretty high standard.
Normal high values we now have according to some of the World Health Organization treatment guidelines, the diagnostic criteria for hypertension is a systolic blood pressure greater than 140, diastolic blood pressure greater than or equal to 90 mm Hg. This is normal and abnormal blood pressure. Diastolic blood pressure is less than 60 mm Hg, systolic blood pressure is less than 90 mm Hg is designated as low blood pressure.
