Under normal circumstances, the common type of sphygmomanometer belongs to the electronic sphygmomanometer, and the correct use of it can be divided into four steps, including laying the forearm flat, placing the cuff, measuring blood pressure, and collecting data.


1. Flat forearm: Before using the sphygmomanometer, it is necessary to lay the forearm flat first, which is more convenient to measure and is conducive to keeping the blood pressure in a stable state.


2. Cuff placement: At this time, the cuff of the sphygmomanometer should be placed on the forearm, and the specific way of placement should be based on the specification standards, if improperly placed, the measurement result may be wrong.


3. Measuring blood pressure: After starting to measure, the number on the sphygmomanometer will fluctuate to a certain extent, and the change in the number will be stable before the measurement is completed. It can usually be measured twice, which is conducive to reducing errors.


4. Data collection: After the measurement is completed, you need to record your blood pressure data. If you measure twice, you can calculate the average value of the two data.


According to the specific model of the blood pressure monitor, there are differences in the way of use. When using, strictly follow the instructions of the manual, and if necessary, operate with the help of a doctor to avoid measurement errors. If blood pressure levels are abnormal, seek medical attention.
