How to measure blood pressure so that it can be more accurate? Doctor: Just do these points
Measuring your own blood pressure is basically one of the "required courses" for every hypertensive patient. Blood pressure is our vital sign. Many patients and friends are more depressed. When doctors or nurses measure their blood pressure, it seems very simple, but when they measure themselves, it is often the first and second times, or the day before and after. There are many differences in blood pressure measured in one day. Which one should 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 one's own blood pressure, blood pressure measurement is a basis for blood pressure control.
If even the blood pressure cannot be measured accurately, how can we accurately determine whether it is high blood pressure, and how to add or subtract medicine?
Especially for patients without high blood pressure, accurate measurement is more important, so when we suspect that we have high blood pressure, we must carefully measure our blood pressure.
Suspected of high blood pressure does not mean that you must have symptoms. Many high blood pressures do not have any symptoms and are found during measurement. Therefore, if you usually do not have high blood pressure, but now you 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 you want to know whether your blood pressure is accurate or not, we first need to figure out the blood pressure and the normal range. Blood pressure is defined as the lateral pressure of blood within the blood vessels against the walls of the blood vessels. Measuring blood pressure usually refers to measuring systolic (high pressure) and diastolic (low pressure) blood pressure.
Normal blood pressure for adults is 90-140 mmHg for systolic blood pressure and 60-90 mmHg for diastolic blood pressure. If it exceeds this standard, 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 need to eliminate several interfering factors that affect the accuracy of blood pressure measurement before 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 at around 6-10 in the morning and around 4-8 in the afternoon, showing "two peaks and one valley". This results in different blood pressure values measured at different times. Therefore, in order to avoid the interference of the time factor, we should choose a fixed time when measuring blood pressure every day, so that the blood pressure measured in the two days before and after can be comparable. So, when is the right time to choose?
Cardiovascular and cerebrovascular diseases mostly occur in the early morning, and blood pressure may have reached its peak around 9 am. Therefore, for patients who only measure their blood pressure once a day, it is recommended to measure their blood pressure around 9:00 in the morning. If you need to measure blood pressure twice a day, you can measure your blood pressure again around 5 pm.
Then when measuring blood pressure, you need to prepare an accurate sphygmomanometer, either a mercury sphygmomanometer or an electronic sphygmomanometer, but it must be very 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 your own quiet state. If you have 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 blood pressure after emptying your bladder, because if you measure it while holding back your urine, it may cause your blood pressure to rise.
When measuring:
Take a seated position. The upper arm needs to be naturally straight, placed on the table, the palm is facing up, the body and mind are relaxed, and the height of the arm is at the same level as the heart.
The distance between the lower edge of the cuff is about 2--3 cm from the elbow socket, and the tightness should be able to penetrate one finger. Too loose, and 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.
After the measurement, you need to record the value of the blood pressure measurement.
Test again after a few minutes interval and record the value.
After a few minutes interval, measure the data for the third time and record it.
After measurement:
Compare these three values, remove the highest value, and take an average of the remaining two.
After the blood pressure measurement, it is necessary to record all the values on the notebook to observe the regularity of your own blood pressure, which is convenient 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 or not, and then you can decide whether you need antihypertensive treatment.
But 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 reduce blood pressure through a healthy lifestyle, even to the point of Finally had to take medicine.
But how many people are willing to take medicine? Probably no one.
