Pulse wave sphygmomanometer and oscillometric sphygmomanometer are good, please recommend one, it is a matter of life and health, please answer seriously. Please also do an introduction

The electronic home blood pressure monitor is a common tool for many hypertensive patients. But often hypertensive patients found that the self-tested blood pressure value and medical personnel measured by the different, and sometimes even a big difference. Recently, the Internet is exposed to the Omron blood pressure monitor measurement of blood pressure is not allowed events, many users have a lot of discussion on this. Whether the brand products are qualified we do not comment, but our clinicians in contact with hypertensive patients found that many patients on the lack of understanding of electronic blood pressure monitors, there are misunderstandings in the use of, and many patients in the purchase of misguided, buy electronic blood pressure monitors are not suitable for their own.

First of all, the medical device industry has incorrectly referred to the oscillometric sphygmomanometer as "electronic sphygmomanometer". In fact, electronic sphygmomanometers are sphygmomanometers that use modern IC components, have built-in programs, and require a power supply. Since their invention, they have been broadly divided into two major categories: oscillometric sphygmomanometers and pulse wave sphygmomanometers, the former of which is an outdated product that is still being produced and sold by many manufacturers.

Compared with mercury sphygmomanometers, electronic sphygmomanometers are much easier to use. Take the oscillometric sphygmomanometer as an example, the oscillometric sphygmomanometer has a lot of limitations, even professional doctors sometimes can't grasp accurately, lack of professional knowledge of the general public can't use it well. The mercury sphygmomanometer is more troublesome to use, but its results are undoubtedly more accurate than the oscillometric sphygmomanometer, which is one of the reasons why most hospitals use mercury sphygmomanometers extensively.

Oscillometric sphygmomanometers are produced by many manufacturers because of their simplicity and imprecise calculation methods. However, different types and brands of oscillometric sphygmomanometers have their respective ranges of applicability and blood pressure measurements, and the measurement of blood pressure within the range is accurate, and beyond the range, the measurement of blood pressure will be inaccurate or may not be able to be measured. Some cuffs for Oscillometric sphygmomanometers also limit the range of use, so if the user's arm circumference is greater or less than the cuff's range of application, the blood pressure measurement may not be accurate. In addition, because of the limitations of the measuring principle of the oscillometric sphygmomanometer, some people with very weak pulse and those with too high or too low blood pressure cannot use it. That is to say, the oscillometric sphygmomanometer is not suitable for all people, the terrible thing is that, before we carry out scientific experiments, is not able to know whether they can belong to the oscillometric sphygmomanometer "applicable to the crowd", in other words, we spend money to buy a home oscillometric sphygmomanometer is likely to be a toy to deceive us. The "Omron sphygmomanometer" incident is one of the best proof that sphygmomanometers vary from person to person.

Unlike the oscillometric sphygmomanometer, the pulse wave sphygmomanometer was designed from the ground up using a very unique concept that takes a different approach to "non-invasive measurements" by linking the fluctuating nature of the human pulse to changes in blood pressure without the need for patterned "calculations". Instead of a standardized "calculation", the specific data measured is used to derive and finally obtain a specific blood pressure value. At the same time, the pulse wave sphygmomanometer will be discontinuous blood pressure measurement throughout, realizing the real-time readings of the changes in blood pressure values, to solve the mercury sphygmomanometer side-ear listening to a momentary change in blood pressure (refers to the sound made by Koch's tone, i.e., the doctor to measure the systolic and diastolic blood pressure heard by the sound of the) embarrassing.

Users in the choice of home electronic sphygmomanometer, first of all, to distinguish between the oscillometric sphygmomanometer and pulse wave sphygmomanometer, especially now on the market most of the electronic sphygmomanometer is the oscillometric sphygmomanometer, be careful to buy. It is recommended to give up the idea of cheap, do not buy oscillometric sphygmomanometer (in fact, many of the so-called large manufacturers of the oscillometric sphygmomanometer price is ridiculously high, completely profiteering), and choose to buy the measurement of accurate pulse wave sphygmomanometer, after all, the health is not allowed to be half false, or the consequences are serious.
