The electronic sphygmomanometer is a medical device that utilizes modern electronic technology and the principle of indirect measurement of blood pressure. The vast majority of blood pressure monitors and automatic electronic sphygmomanometers use the oscillometric method of indirect blood pressure measurement. Oscillometric method of blood pressure measurement by establishing the relationship between systolic, diastolic, and average pressure and cuff pressure shock wave to identify the blood pressure.
There are two main types of electronic blood pressure monitors for home use, one is arm-type and the other is wrist-type, both of which are suitable for healthy people. However, wrist-type electronic blood pressure monitors are not suitable for patients suffering from blood circulation disorders; diabetes, high blood cholesterol, hypertension and other diseases will accelerate arteriosclerosis, thus causing peripheral circulation disorders in the patient, these patients have a large difference between the wrist blood pressure and the upper arm blood pressure measurements, and should not be used with the wrist-type.
Expanded Information
The level of home blood pressure measurements is usually lower than that of office blood pressure measurements, with a home blood pressure of 135/85 mm Hg being equivalent to an office blood pressure of 140/90 mm Hg. Moreover, the average of 3 measurements taken on the same day, but any greater than 135/85 mm Hg, should be suspected of hypertension.
Patients who measure their own blood pressure at home without professional guidance are at this point involved in a question of accuracy. If the blood pressure is stable and up to standard, measure yourself 1 day a week, once in the morning and once in the evening. If the blood pressure is measured in obese patients, then the straps are too tight and too small, and the blood pressure test will come out higher than the actual value. Therefore, those with thick upper arms or well-developed biceps should use longer and wider cuffs to compress the brachial artery.
