Is The Blood Pressure Monitor Accurate? 3 Aspects To Help You Easily Judge

Sometimes we  measure blood pressure, today is one data, tomorrow is another data, each time the measured data will have significant errors, so we will worry about whether there is a problem with our health, and worry all day long about diet and daily life. They are strictly controlled, but in fact, sometimes it may not be their own problem, and the accuracy of the blood pressure monitor will also have an impact.There are many types of sphygmomanometers. The most common ones are fingertip, wrist and upper arm type. Because of the measurement accuracy, the first two are not as good as the third upper arm type. upper arm sphygmomanometer. The upper arm sphygmomanometer is not only a commonly used blood pressure measuring instrument in medical institutions, but also a commonly used blood pressure measuring instrument in families. To judge whether the data of the instrument is accurate, it can be seen from the following three aspects.  1- The instrument manufacturer follows the standard  Whether the data of the sphygmomanometer is accurate can be judged from the standards followed by the manufacturer of the sphygmomanometer. There are three main standards: the American Medical Device Association standard, the British Hypertension Association standard, and the European Hypertension Association standard. These three are international standards and are also relatively authoritative data standards. If manufacturers use these three standards as the basis Production quality, data accuracy will be more credible.  2-Compare mercury sphygmomanometer data  Mercury measuring instruments have been gradually replaced by electronic measuring instruments because of their safety, but as a direct contact measuring instrument, the data is still very reliable. You can use a special mercury sphygmomanometer in the hospital to measure first, and then take three sets of data. In the same environment and the same method, the electronic sphygmomanometer was used for measurement, and three groups of data were also compared.  Under normal circumstances, the data error of two different instruments should not exceed 5mmhg. If it exceeds, the error value is large, and the instrument needs to be calibrated and maintained.  3- Confirm whether the data error is an operational effect  In addition to the above two situations, sometimes the measurement data of our sphygmomanometer has a large error, which may not be a problem of the instrument, and improper operation may also have an impact. When measuring, the strap needs to be about 3 cm above the elbow socket to ensure that there is no gap between the strap and the arm. Avoid the influence of air factors, try not to move your body, and keep still. At the same time, it is also necessary to maintain emotional stability to avoid large emotional fluctuations affecting the measurement data.  If there is still an error in the instrument if the operation is standardized, it can be considered to be the problem of the instrument itself. For instrument calibration and maintenance of the sphygmomanometer, you can first contact the manufacturer for advice, or you can find a local authority for testing, or some have strong qualifications. However, the instrument calibration does not repair the instrument, but only detects whether the instrument data is accurate and normal, and whether it can be used normally. This point should be clarified first.https://www.arshinemedical.com...
