1. The purchase needs to see the “standard”
This “mark” means standard and logo.
It is not just a matter of buying a sphygmomanometer. It is recommended that you buy an electronic sphygmomanometer that has passed the international standard certification. The certification standards include the British Hypertension Association standard, the European Hypertension Association standard, or the American Medical Device Association standard. These contents will be clearly marked on the packaging of the electronic sphygmomanometer. In addition, on the official website of the my country Hypertension League, the certified brands and models of electronic sphygmomanometers are publicized, and you can refer to the Internet.
2, the preferred “upper arm”
At present, the electronic sphygmomanometers on the market include arm type, wrist type, finger type, etc. However, the values measured by the wrist type and finger type are not accurate enough. Studies have shown no difference in the degree of accuracy between certified arm-mounted electronic blood pressure monitors and table-top mercury blood pressure monitors. my country’s hypertension guidelines also recommend the use of an arm-type electronic sphygmomanometer.
I don’t know if you have noticed. Now, most of the blood pressure monitors used in outpatient or emergency departments in many hospitals are replaced by arm tube electronic blood pressure monitors. This electronic sphygmomanometer does not require manual tying of cuffs, further reducing measurement errors. Conditional families can also choose.
3. Select the appropriate cuff according to the size of the upper arm and arm circumference
Most electronic sphygmomanometers have a cuff length of 35cm and a width of 12-13cm. This size is suitable for people with an arm circumference of 25-35cm.
However, people who are obese or have larger arm circumferences should use a larger size cuff, and children should use a smaller size cuff.
4. Avoid interference during measurement
The cuff is too tight or improperly positioned, body movement, etc. will cause measurement errors; avoid using the electronic sphygmomanometer in the surrounding electric field to prevent interference by the electric field and affect the measurement accuracy; do not shake the table on which the electronic sphygmomanometer is placed when measuring blood pressure ; Ensure that the power supply is sufficient, because both the inflation and the liquid crystal display consume power, and the lack of power will also affect the accuracy of the measurement.
5. Pay attention to people who are not suitable for using electronic sphygmomanometers
1) Obese people.
2) Patients with arrhythmia.
3) Patients with very weak pulse, severe breathing difficulties or hypothermia.
4) Patients with heart rate below 40 beats per minute and above 240 beats per minute.
5) Patients with Parkinson’s disease.
