The risk of hypertension is relatively high, and there are now more patients with hypertension. For families with high blood pressure, it is necessary to buy an electronic sphygmomanometer, because the price of the electronic sphygmomanometer is not expensive, and the blood pressure of the patient can be measured at any time. If the patient’s blood pressure is not good, you can see a doctor in time. The purchase of an electronic sphygmomanometer requires proper use. When using an electronic blood pressure monitor, the most important thing is to calibrate the electronic blood pressure monitor correctly. So, how much do you know about the calibration method of an electronic blood pressure monitor?
Before using an electronic sphygmomanometer, you first need to determine whether the electronic sphygmomanometer is accurate. At this time, the electronic blood pressure monitor needs to be calibrated. First of all, we measure the patient’s blood pressure with a mercury column type sphygmomanometer, wait for three minutes, and then measure it with an electronic sphygmomanometer. Of course, every measurement value needs to be recorded. Let’s take a rest for 3 minutes, and take another measurement with a mercury-type sphygmomanometer. Let’s take the average of the first and third blood pressure measurements, and see how it compares with the second measurement with an electronic sphygmomanometer. What is the range of the difference in blood pressure value? If it is less than 5 mmHg, the accuracy of the electronic sphygmomanometer used is very high. The blood pressure measured by this electronic sphygmomanometer product is accurate
