There are many types of sphygmomanometers, including mercury, electronic, and barometer, which one to choose How about the blood pressure monitor? How can the measurement result be more accurate? Let’s take a look together below.

When is the most accurate time to measure blood pressure?

The blood pressure in the human body fluctuates throughout the day. When measuring blood pressure, it is recommended to choose electronic blood pressure Therefore, it should be measured when the blood pressure value is relatively high. The change of blood pressure in a day has the characteristics of “two peaks and one valley”.

It is recommended that hypertensive patients measure blood pressure at two peak time points, which are six in the morning To ten o’clock and four to six o’clock in the afternoon, “Yigu” is at 2:00~4:00 at night.

If the blood pressure fluctuations meet this situation, you can measure your blood pressure after getting up in the morning and take antihypertensive drugs The patient measures blood pressure before taking the medicine, then waits until around 10 o’clock to measure again, and measures again at four or five o’clock in the afternoon.

If the blood pressure does not meet this In other cases, the blood pressure is high during the day and high at night. It is also necessary to measure the blood pressure before going to bed. If it cannot be measured multiple times a day, it can be measured once in the morning and evening.


When measuring blood pressure, is the right hand or the left hand measured?

There are mercury and electronic blood pressure monitors. Mercury blood pressure monitors are durable and not prone to accidents Fault, accurate diagnosis and small error, it is often widely used in clinical departments.

The electronic sphygmomanometer is relatively small in size, very convenient to use and carry, suitable for family use An electronic sphygmomanometer can reduce the number and time of going to the hospital, and is very suitable for middle-aged and elderly hypertensive patients.

You should choose the right hand when measuring blood pressure , because the right skeletal artery comes from the branch of the brachiocephalic trunk, and the left ventricular arch artery comes from the left subclavian artery. The brachiocephalic trunk is a relatively large branch of the aorta, so the blood pressure of the right upper arm will be higher than that of the left.

If there is a disease in the heart or blood vessels, the blood pressure on the left wall is higher than that on the right arm, and the blood pressure difference between the left and right arms is 5~10 mmHg, if the blood pressure measured by both hands is greater than 20 mmHg, it may be a cardiovascular and cerebrovascular disease.


When measuring blood pressure, if you do not pay attention to 5 things, it may be equivalent to a white test

Newly purchased blood pressure monitors must be calibrated first

The sphygmomanometer should be calibrated before use to see if the pointer is in position. If there is any deviation, then it should be adjusted in time, and it has not been used for a long time The sphygmomanometer also needs to be calibrated. If you don’t know how to do it, you can refer to the instructions.

Note Posture

Many people do not know what posture to maintain when measuring blood pressure. Different postures will have a certain impact on the blood pressure value. If the posture is wrong, the measured blood pressure value will be inaccurate.

The correct way is to keep your body upright when measuring blood pressure, and do not walk or Speaking, the position of the bandage should be level with the heart, only in this way will the measured blood pressure be more accurate.

Wait for the body to completely calm down

If you are excited, angry, exercising, taking medicine, taking a bath, etc., then do not measure blood pressure first, and wait until the body is completely calm before measuring Blood pressure, reduce external interference, and the measured blood pressure is accurate.

Avoid smoking or drinking coffee

Do not smoke or drink coffee half an hour before measuring blood pressure, this is because certain substances in cigarettes will cause blood circulation in the human body when drinking coffee The speed becomes faster, causing the blood pressure to change, so the blood pressure measured at this time is generally on the high side.

Can’t hold back urine

When the human body is holding back urine, the blood pressure will fluctuate greatly due to the protection of the bladder. In this case, it is not suitable to measure blood pressure, so measure blood pressure Avoid holding back urine when you are pregnant, and don’t hold back urine at ordinary times, because it will bring adverse health consequences.
