Electronic sphygmomanometer is not allowed - the accuracy of the instrument itself to detect
1
Electronic sphygmomanometer is not allowed, there are two reasons: one. The accuracy of the instrument itself; two. The user's operation problems. Both can lead to the electronic blood pressure meter is not allowed.
Regular qualification. Now on the market electronic sphygmomanometer brands, formal and informal electronic sphygmomanometer products mixed in, China has strict regulations for medical devices, production must have a medical device production license, sales must have a medical device registration number, so we need to buy electronic sphygmomanometer before the purchase of electronic sphygmomanometer qualifications related to the purchase of electronic sphygmomanometer to check, to exclude the informal crude electronic sphygmomanometer, this is to ensure the accuracy of the electronic sphygmomanometer. This is the basis for ensuring the accuracy of the electronic sphygmomanometer.

Repeated comparison method. Production process, production technology differences, will also affect the accuracy of the electronic sphygmomanometer, and, the production of electronic sphygmomanometer, inevitably there will be a certain chance of non-qualified products into the qualified products. Therefore, we can through the electronic sphygmomanometer in different periods of time many repeated measurements, observation of the results of the data detected, compared to the electronic sphygmomanometer test stability, accuracy, fluctuation range. The prerequisite for this method is that one needs to have some knowledge about his/her own blood pressure. If you have the conditions, you can get to the doctor, with the electronic measurement, and then measured with the mercury, then the electronic on the reading should be reduced or increased by how much, the following should be reduced or increased by how much, before the same with the mercury, after four or five tests on the two values, then measured at home is accurate.

Electronic sphygmomanometer is not allowed - the correct operation of the use
1
Correctly select the type of electronic sphygmomanometer. Electronic sphygmomanometers are divided into wrist and arm type two kinds, wrist electronic sphygmomanometer mainly for the wrist at the small artery detection, arm electronic sphygmomanometer mainly for the left arm at the large artery detection. Due to the aging of middle-aged and elderly blood vessels or the existence of cardiovascular and cerebrovascular diseases, the fluctuations of the small arteries at the wrist are very difficult to be wrist electronic sphygmomanometer to capture the signal, and the left arm of the large arteries away from the human heart nearest to the cardiovascular fluctuations of the most stable and clear, it is easy to be arm electronic sphygmomanometer to capture the signal, so the wrist electronic sphygmomanometer is suitable for the use of young people without cardiovascular and cerebrovascular diseases, middle-aged and elderly people are suitable for the arm electronic sphygmomanometer. Therefore, wrist-type electronic sphygmomanometer is suitable for young people without cardiovascular and cerebrovascular diseases, middle-aged and old people are suitable for arm-type electronic sphygmomanometer, and arm-type electronic sphygmomanometer is also very suitable for the whole family.

Arm or wrist straps are worn correctly. Whether arm-type electronic sphygmomanometer or wrist-type electronic sphygmomanometer, for the arm band and wrist strap should not be bundled too tight or too loose, too tight, no matter too loose, too tight will make the blood pressure measurement value is low.
Wrist electronic sphygmomanometer wrist strap tying method:
1. Palm up, the product is also up, and will be tied to the wrist strap from the wrist joints at 1 cm;
2. Will be below the part of the wrist strap, with the right hand thumb to hold down the upper part of the rest of the fingers pulled upward to tie;
3. Measurement of the posture will be upward relaxation of the palm of the hand, the left hand placed in a hard box to make the wrist strap position and heart as high as the heart, the wrist strap position is not as high as the heart, and will be tied to the wrist strap to make the wrist strap. The position of the wrist strap is the same as the heart, otherwise it is impossible to measure the correct blood pressure.
Arm-type electronic sphygmomanometer arm band tying method:
1. Open the arm band of the electronic sphygmomanometer to avoid the arm band slipping out of the metal ring;
2. Measurement of the bare arm, if you are wearing a thicker shirt, do not roll up the long sleeves when measuring, you should remove the shirt;
3. Put the arm band of the electronic sphygmomanometer on your left arm, and the bottom of the band should be above the elbow 1-2 cm, and the green marking should be on the elbow. The bottom of the arm band should be 1-2 centimeters above the elbow, the green marking should be located on the artery on the inner side of the arm, and the air tube should be in the extension line of the middle finger (palm direction) while keeping the arm at the same level as the heart;
4. Hold the end of the arm band and tightly wrap the band around the arm as you pull it.

Correct measurement posture and body condition.
Several states of the body's blood pressure:
1. Blood pressure is generally lower at night than during the day, and there are two peaks of blood pressure during the day, which are 8-10 a.m. and 4-6 p.m.
2. Blood pressure is lower in summer than in winter;
3. Generally, the blood pressure of the right arm is higher than that of the left arm blood pressure.
There are several states that affect the body's blood pressure: smoking, exercise, talking during measurement, bathing, drinking alcohol, stress, temperature changes, etc.
So, using an electronic blood pressure monitor requires diligent blood pressure measurement, and it is recommended that you take one measurement in the morning, one in the middle of the day and one in the evening, and keep a record of it, as well as measure your blood pressure at the same time period, in the same environment, in the same mood, and in the same position.
Correct measurement posture: The correct measurement posture should be sitting, the cuff and the heart should be at the same level, the upper arm is naturally drooping, the elbow and forearm are naturally resting on the table, and the palm of the hand is up.

Precautions
Repeated and continuous measurements can cause poor blood flow due to compression of the arm, causing changes in the blood pressure value; therefore, when continuously measuring the same person, the cuff should be loosened so that the arm can rest for 3 minutes.
Before measurement, you should rest in a quiet environment for at least 5 minutes; avoid measuring when you are cold or holding urine.
