Will the sphygmomanometer be affected by the weather? Many people find that measuring blood pressure in summer is lower than in winter, and they are worried about whether the electronic sphygmomanometer is frozen or sunburned. In fact, this is not the problem of electronic sphygmomanometer, but the fluctuation of human blood pressure with seasonal changes. At this time, drugs should be adjusted appropriately under the guidance of doctors.
Why is the blood pressure measured at home lower than that measured at the hospital? This is due to the different sphygmomanometers used. According to the guidelines for prevention and treatment of hypertension, the upper arm automatic or semi-automatic electronic sphygmomanometer is used, and the self-measured blood pressure at home is 135/85 mm Hg, which is equivalent to 140/90 mm Hg of clinical mercury sphygmomanometer. Therefore, when the self-measured blood pressure exceeds 135/85 mm Hg, attention should be paid to it.
Is the electronic sphygmomanometer accurate after several years of use? Because the electronic sphygmomanometer does not need to add mercury, generally speaking, it does not need special calibration, and the battery can be replaced or charged in time. When you doubt its accuracy, you can go to a professional maintenance point for testing. ▲
