With the rapid development of modern society, people are under increasing pressure, which makes hypertension, the "king of chronic diseases", gradually approaching. Not only the elderly have become the target, but in recent years, the trend of hypertension has become more and more obvious.
In the course of hypertensive lesions, patients may experience symptoms such as dizziness, nausea, chest tightness, and in severe cases, cerebral infarction.
However, with the popularization and deepening of medical science, people have a basic understanding of hypertension and understand that it is a warning signal from the body, indicating that they are already in a sub-healthy state.
As a result, many people monitor changes in their indicators by measuring their blood pressure regularly. However, during the process of measuring blood pressure, many people find that their blood pressure is higher at the first measurement and gradually decreases with subsequent measurements.
This makes them wonder if there is something wrong with their measurement technique or the blood pressure monitor they have bought. They are confused and unsure if their blood pressure is within the normal range and whether they should take medication intervention.
1) Factors influencing blood pressure measurements
First and foremost, the accuracy and reliability of the measurement equipment is crucial. Blood pressure monitors need to be calibrated regularly to ensure that the measurements are accurate.
In addition, it is important to choose the right cuff size to ensure that the cuff fits snugly on the arm during the measurement process and that errors can be avoided.
Secondly, the skill level and experience of the measurer are also important factors that affect the blood pressure measurement. Surveyors need to master the correct measurement method, including proper cuff placement, inflation and deflation. In addition, the surveyor also needs to pay attention to some details, such as keeping quiet and avoiding strenuous exercise before the measurement.
In addition, some physiological factors may also affect blood pressure measurements. For example, factors such as age, gender, height, weight, etc., may affect blood pressure levels.
At the same time, some disease states such as high blood pressure and heart disease may also affect blood pressure measurements. Therefore, these factors need to be taken into account when measuring blood pressure and corresponding measures should be taken to reduce errors.
Finally, it is important to note that blood pressure may fluctuate even within the same day. Therefore, during the diagnosis and ** process, blood pressure needs to be measured several times and a comprehensive assessment is performed to obtain a more accurate blood pressure level.
2) Why does my blood pressure get lower and lower?
Blood pressure is affected by many factors. When we first measure our blood pressure, we may be in a state of nervousness, anxiety, or just having a strenuous exercise.
All of these factors can lead to an increase in blood pressure. And when we gradually adapt to these states, or after a period of rest, blood pressure will naturally drop.
Secondly, the methods and techniques for measuring blood pressure may also affect the results. If the measurement method is incorrect, or if there is an error in the equipment used, the measurement results may also be inaccurate. Therefore, when measuring blood pressure, we need to make sure that we are using the right methods and equipment to get more accurate measurement results.
In addition, some diseases or medications can also cause changes in blood pressure. For example, some people with high blood pressure may experience a gradual drop in blood pressure after taking antihypertensive medications. Some other medical conditions can also affect how blood pressure is measured.
3) Which is the standard?
Because measuring blood pressure is affected by a variety of factors and is difficult to control, doctors in hospitals often recommend that patients have their blood pressure measured multiple times at home.
Ambulatory blood pressure testing is recommended when white coat hypertension, occult hypertension, and refractory hypertension are suspected.
When self-measuring blood pressure at home, according to the criteria of Diagnostics, the normal blood pressure value for self-measuring blood pressure at home is 135 85 mmHg, which is different from 140 90 mmHg in a clinic or hospital.
In order to obtain a more accurate blood pressure number, it is generally recommended to take two consecutive blood pressure measurements at home, taking the average. If you find that the difference between the two blood pressure measurements is 5mmHg, it is recommended to measure the blood pressure for the third time, remove the value that is too large, and take the average of the two values that are similar to the two values in the three measurements as your blood pressure.
If you find that the difference is still very large, it is recommended to go to the clinic or hospital as soon as possible to avoid falling into a vicious circle due to emotional problems that lead to higher or lower tests. Whether it is a low test or a large gap after multiple measurements, it is recommended to seek medical attention according to your own situation.
The diagnosis of hypertension is mainly measured in the office, and the home measurement data is mainly used to observe the prevention and control of the individual. Middle-aged and elderly people like Aunt Wang, do not despise the follow-up because the blood pressure measured at home is getting lower and lower, stop or change the medication at will, and do not monitor blood pressure regularly according to the doctor's instructions.
In order to arrive at a more standard blood pressure measurement, we need to follow some norms and pay attention to detail. First of all, we need to ensure the accuracy and reliability of the measurement equipment.
Blood pressure monitors should be professionally calibrated to ensure the accuracy of their measurements. In addition, we should use the appropriate cuff size and choose the right cuff according to the patient's arm circumference to ensure the accuracy of the measurement.
Second, we need to take the right measurements. Before measuring blood pressure, patients should sit still for a few minutes to avoid inaccurate measurements due to activity.
When measuring, the cuff of the sphygmomanometer should be wrapped around the patient's upper arm with a moderate tightness that can be inserted into two fingers. At the same time, the probe of the stethoscope should be placed under the cuff and gently pressed to make the cuff fit with **.
Then, turn on the sphygmomanometer and inflate, which should be applied at a constant rate during the inflation process, avoiding too fast or too slow. When the first pulsation is heard, it is systolic blood pressureContinue to apply pressure until the sound disappears, which is diastolic.
In addition, there are some details that we should pay attention to. For example, you should avoid drinking, smoking, or drinking caffeinated beverages before your blood pressure is measured, as these factors may cause your blood pressure to rise.
In addition, measurements should be carried out in the same environment and conditions to avoid inaccurate measurement results due to environmental changes. For example, blood pressure should be measured in a quiet, relaxed state and without talking or moving.
1.Lifestyle habits
First and foremost, maintaining healthy lifestyle habits is key to preventing high blood pressure. This includes maintaining a regular sleep schedule and avoiding staying up late and overexertion.
At the same time, maintain an appropriate amount of exercise, such as at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming.
In addition, it is very important to maintain a healthy diet. It is recommended to reduce salt intake, increase fruit and vegetable intake, and avoid excessive alcohol consumption and smoking.
2.Rational use of medicines
For some people who already have high blood pressure or are at risk of high blood pressure, it is very important to use their medications wisely. With the advice of a doctor, the use of appropriate antihypertensive medications can effectively control blood pressure and reduce the risk of complications. However, be sure to use the medicine under the guidance of a doctor and do not buy and use it on your own.
3.Long-term monitoring
Finally, long-term monitoring of blood pressure is one of the important measures to prevent hypertension. It is recommended to have regular blood pressure checks to know your blood pressure status. If high blood pressure is found or there is a risk of hypertension, timely measures are taken to intervene and**.
