Why is the value measured at home higher than that in the hospital? Why do continuous measurements show different results? Measurement Notes 1. Please measure blood pressure at the same time, with the same hand and in the same posture every day. Measuring at home with a stable mood and a suitable environment is generally 10 to 20 mm Hg lower than the value measured in the hospital, so it is very important to know your blood pressure at home when you are calm. resulting in lower measured values. 1. The winding position of the cuff is inaccurate, such as: the cuff is too high or too low, causing the sphygmomanometer to fail to capture the arterial signal, which will lead to high measured values. 2. Incorrect posture during measurement, bending over, sitting cross-legged and other postures that are prone to abdominal pressure; 3. The position of the cuff is lower than the level of the heart, resulting in higher blood pressure in the arm than in the heart 4. The position of the cuff is correct, but it is too loose so that the pressure cannot be transmitted to the artery, resulting in high blood pressure. 5. People who take antihypertensive drugs will cause high blood pressure when the drug loses its effect. 1. Repeated and continuous measurement will cause blood vessel compression and lead to poor blood circulation, which may easily cause changes in blood pressure. It is recommended to rest for 10 minutes before measuring 2. Medical experiments have proved that the blood pressure of a normal person fluctuates throughout the day. When a person sleeps, the blood pressure is low, and the blood pressure is high at 8-10 in the morning. Even at night, when people are sleeping, there are fluctuations of 5-10mmHg. In fact, the value measured by the electronic sphygmomanometer reflects the blood pressure value at the moment of human body measurement. The blood pressure of the human body is constantly changing, and it is very rare to get the same blood pressure twice. Therefore, only by measuring the blood pressure with the same hand and the same posture at the same time every day can a comparable blood pressure value be obtained. The best measurement time is within half an hour after getting up early, after urinating, and on an empty stomach. 3. You must keep quiet for 4-5 minutes before measuring. 2. Please measure in the morning when there is no urge to urinate after waking up, but if it is not possible to measure at that time, please measure before eating and when the body has not been exercising. 1 2 3 4 5 Are traditional sphygmomanometers more accurate than electronic sphygmomanometers? Kind tips The measurement is sometimes accurate, sometimes inaccurate, and the measured value fluctuates greatly The electronic sphygmomanometer adopts the principle of the oscillometric method, so the sensitivity is high, and slight changes in blood pressure measurement (such as speaking, sudden tension) can affect the measurement results, so the electronic sphygmomanometer is accurate to single digits, and the mercury sphygmomanometer uses auscultation , the sensitivity is low, and it is shown that the repeatability of multiple measurements is good, not the accuracy is higher. 1. Battery type: Insufficient power will cause measurement failure. It is recommended to use alkaline batteries (such as Nanhu batteries). Insufficient power of ordinary carbon batteries will cause measurement failure. Removing the battery when the sphygmomanometer is not in use can increase the battery life. 2. Charging model: It is recommended to unplug the charging cable after charging the new machine for 4 hours before using it. It is enough to charge it for 3-4 hours at ordinary times. The charging cable can be plugged into the mobile phone charger to charge. Answer: To monitor blood pressure at ordinary times, we recommend measuring at the same time every day. It is more scientific and accurate to compare the data measured at the same time period every day.
