How to measure blood pressure, can be more accurate? Doctor: Just do these things
Measuring your own blood pressure is basically one of the "compulsory courses" for every hypertensive patient. Blood pressure is our vital sign. Many patients and friends are quite depressed. When doctors or nurses measure their blood pressure, it seems very simple, but when they measure it by themselves, it is often the first time and the second time, or the day before and the day after. There are many gaps in the blood pressure measured in a day, which one shall prevail? so, what happened? There are many reasons for this, and we will explain them in detail below.
Since modern electronic sphygmomanometers have entered thousands of households, let's take electronic sphygmomanometers as an example to understand the correct measurement of blood pressure. Because only accurate measurement can effectively control your own blood pressure, so measuring blood pressure is a basis for controlling blood pressure.
If even the blood pressure is not accurate, how can we accurately judge whether it is high blood pressure, how to add or subtract medicine?
Especially for patients who have never had high blood pressure, accurate measurement is even more important. Therefore, when we suspect that we have high blood pressure, we must carefully measure our own blood pressure.
Suspecting high blood pressure does not mean that you must have symptoms. Many high blood pressures do not have any symptoms and are discovered during measurement. Therefore, if you do not usually have high blood pressure, but now find that your blood pressure is high, then you must Take a serious measurement again to determine whether you have high blood pressure.
But if we want to know whether our blood pressure is accurate or not, we first need to figure out the blood pressure and the normal range. The definition of blood pressure is: the lateral pressure of the blood in the blood vessel on the blood vessel wall. Measuring blood pressure usually refers to measuring systolic (high pressure) and diastolic (low pressure) pressure.
Normal blood pressure for adults is: systolic blood pressure 90--140 mm Hg, diastolic blood pressure 60-90 mm Hg. If once this standard is exceeded, then it is high blood pressure. But in real life, many people say that the blood pressure measurement is inaccurate, wondering if their blood pressure monitor is broken? First of all, you have to eliminate several interfering factors that affect the accuracy of blood pressure measurement, so that you can measure your own blood pressure accurately.
Choose the right time to measure your blood pressure:
Our blood pressure fluctuates to a certain extent every day. The blood pressure is the highest around 6-10 am and 4-8 pm, showing "two peaks and one valley". This leads to different values of blood pressure measured at different times. Therefore, in order to avoid the interference of time factors, we should choose a fixed time when measuring blood pressure every day, so that the blood pressure measured two days before and after will be comparable. So, when is the right time to choose?
Cardiovascular and cerebrovascular diseases mostly occur in the early morning, and at around 9 am, blood pressure may have reached its peak. Therefore, for patients who only measure their blood pressure once a day, it is recommended to measure their own blood pressure around 9 o'clock in the morning. If patients need to measure blood pressure twice a day, they can measure their own blood pressure again around 5 pm.
Then when measuring blood pressure, you need to prepare an accurate sphygmomanometer. Mercury sphygmomanometer or electronic sphygmomanometer can be used, but it must be particularly accurate. Under the premise of an accurate sphygmomanometer, the correct method is even more important. .
Preparation before measuring blood pressure:
You need to measure in a quiet state. If you just finished exercising, you need to rest for about 10 minutes.
Try to avoid drinking alcohol or drinking strong tea, coffee, etc. 30 minutes before the measurement.
Measure your own blood pressure after emptying your bladder, because if you measure while holding back your urine, it may cause your own blood pressure to rise.
When measuring:
Take the seat, the upper arm needs to be straightened naturally, put it on the table, palms facing up, relax physically and mentally, the height of the arm is at the same level as the heart.
The distance from the lower edge of the cuff to the elbow fossa is about 2-3 cm, and the degree of tightness should be as deep as one finger. If it is too loose, the measured blood pressure may be high; but if it is too tight, the measured blood pressure may be low.
Turn on the switch of the sphygmomanometer and try to avoid talking during the measurement process.
After the measurement is over, it is necessary to record the value of the blood pressure measurement.
Measure again after a few minutes interval, and record the value.
After a few minutes, measure the data for the third time and record it.
After measurement:
Compare the values of these three times, remove the highest value, and take an average of the remaining two.
After the blood pressure measurement, you need to record all the values in the notebook to observe the law of your own blood pressure, so as to provide a certain reference for the doctor to adjust the plan in the future.
Because only the correct measurement method + accurate sphygmomanometer can accurately judge whether you have high blood pressure, and then you can decide whether you need antihypertensive treatment.
But regardless of whether we have high blood pressure or not, we must maintain a healthy lifestyle, because prevention is the best treatment, but once high blood pressure is found, it is very difficult to lower blood pressure through a healthy lifestyle, even to Finally had to take medicine.
But how many people are willing to take medicine? I'm afraid there is no one.
