Be careful, home electronic blood pressure meter will have error

In the Chung Yeung Festival just past, Mr. Sun bought a home electronic blood pressure monitor for his father. After several days of measurement at home, the father’s blood pressure data was within the normal range. The elderly happily squatted with low blood pressure and could reduce the drug.

Mr. Sun was guilty of being guilty. His father was plagued by high blood pressure for more than two years. How could he come down? Yesterday, he took the old man to the hospital for a check and found that the blood pressure did not fall back. The doctor told Mr. Sun that it should be a problem with his home blood pressure monitor. Most of them are measured and stored improperly.

“The reasons for inaccurate self-test at home are mostly caused by improper measurement methods,” said Jiang Dongsheng, an expert in kidney medicine at the Municipal People's Hospital. It is understood that household wrist electronic blood pressure meters are generally lower than those measured by medical mercury column blood pressure meters. In this way, it may be even more misleading for a patient with a large difference between the blood pressure of the wrist and that of the upper arm to think that the blood pressure has dropped.

On the other hand, improper storage is also a reason that cannot be ignored. When Uncle Xu, who lives in Wenxin Court, measured blood pressure at home, he missed the blood pressure meter and dropped it to the ground. After getting up and found that blood pressure meter can be used, plus self-test blood pressure is stable, it has not been to the hospital for review. It was not until the medical examination that high blood pressure was found. A check, found that the instrument has been damaged. Regularly check the blood pressure meter, it is best to go to the hospital to check how to avoid measurement error? According to Jiang Dongsheng, home electronic sphygmomanometers need to be calibrated regularly, especially if sphygmomanometers have been used for some years, and the errors tend to increase. “At the same time, do not exercise vigorously for half an hour before measuring blood pressure in your home and keep your spirit relaxed.” Jiang Dongsheng reminded that there are certain errors in the blood pressure measured by the electronic blood pressure meter and can only be used as a reference for blood pressure changes. If problems are found, they should go to the hospital for further examination. "It is recommended that patients with high blood pressure and other diseases should regularly go to the hospital for blood pressure tests."
