Core tips: for patients with hypertension, not only to actively control blood pressure, do a good job in regular monitoring of blood pressure is also an important aspect of strengthening blood pressure control. Daily blood pressure measurement is very important for patients with hypertension, but many people do not know when the best time to measure blood pressure, which often leads to hypertension patients can not accurately understand their blood pressure, thus missing the best treatment period.

What time of day measure blood pressure best?
Although our blood pressure has a normal range, usually below 140 / 90mmHg is the normal level, but the blood pressure is not invariable within 24 hours, but is in dynamic fluctuation. Generally, the blood pressure rises rapidly after getting up in the morning and reaches the first peak at 6-10 a.m.; it is basically at a higher level during the day, with the second peak at 4-6 p.m., and after 6 p.m The blood pressure will reach the lowest level at night, showing "two peaks and one valley" one day
1、 When is blood pressure measured most accurately
For patients with hypertension, in addition to recording this accurate value, it is also necessary to record their blood pressure before and after taking medicine according to their own situation.
Generally, after getting up in the morning and sleeping all night, the body's metabolic activities are less and the impact on blood pressure is small. At this time, blood pressure measurement is more accurate and objective. The blood pressure level at this time can reflect whether the efficacy of antihypertensive drugs can last until the next morning. If your blood pressure is very high after you get up in the morning, you should measure 24-hour ambulatory blood pressure to understand the blood pressure status during sleep.
Thirdly, blood pressure measurement at about 10:00 a.m. can reflect the change of blood pressure after taking medicine. Blood pressure measurement from 2:00 p.m. to 3:00 p.m. can reflect the rebound of blood pressure. The blood pressure measurement before and after dinner can reflect the control of blood pressure after taking antihypertensive drugs.
Finally, after dinner, the measurement should be conducted around 8:00 p.m., which is instructive for the adjustment and reduction of night blood pressure and stroke. It should be noted that the blood pressure monitoring is dynamic. During the unstable period and the initial medication stage, blood pressure monitoring should be carried out all day. When the condition is stable, you can test it every morning. When measuring blood pressure, it is better to measure two or three times, and then take the average value will be more accurate.
2、 What problems should be paid attention to when measuring blood pressure?
1. The sphygmomanometer should be checked before measurement, and it can be used only if it meets the requirements. If the electronic sphygmomanometer has been calibrated, whether the mercury sphygmomanometer reaches the standard, and the mercury is insufficient, the blood pressure value can be on the low side.
2. The measured person's mood should be peaceful. Generally, the measurement should be made 30 minutes after exercise. It is forbidden to measure the strong tea, coffee or even smoking in the first half hour. For patients who need to closely observe their blood pressure, they should do "four fixations", that is, fixed time, fixed position, fixed position and blood pressure meter, so as to ensure the accuracy and comparability of measured blood pressure.
3. When measuring blood pressure, the "0" point of sphygmomanometer should be at the same level as the heart and brachial artery. In the sitting position, the brachial artery was flat to the fourth costal cartilage, while in the supine position, the brachial artery was at the level of axillary midline. When measuring, it is better to relax the muscles of the whole body. It is better to measure the arm of the right hand. When measuring, the sleeve should be rolled up, and the final measurement result should not be affected by the clothes.
4. The tested person should pay attention to the emptying of urine. Some patients usually take a sitting position and sit upright. The seat should be comfortable. The upper arm should be exposed. The forearm should be flat on the table top. The cuff should be at the same level as the heart. Keep your breath steady. Don't talk to people. Don't look around. Don't keep your eyes on the mercury of the sphygmomanometer.
5. Don't worry too much about the blood pressure. Blood pressure itself has circadian rhythm changes, and is affected by many factors, so there is a certain fluctuation. Don't adjust the dosage of medicine just because of the blood pressure measured several times, which is not conducive to the stability of blood pressure.
