Improvement of people's living standards，The blood pressure of the elderly has also begun to gradually increase，Don't drop it lightly， Many acute diseases Especially cardiovascular and cerebrovascular diseases， Is caused by high blood pressure。therefore，Regular measuring blood pressure and take medicine on time，This is very important for each hypertensive patient.。
易彤破壁机全国维修点There are various electronic sphygmomanometers in the domestic market.。But due to the use of methods，The old man is hard to measure the accurate blood pressure.。therefore， I believe that the traditional mercury sphygmomanometer is more accurate。He even laughed even to the electronic blood pressure of his child.。In fact，There is no significant difference between the blood pressure gauge blood pressure gap.。Silver blood pressure gapKorotkoffmethod，Electronic sphygmomanometer。KorotkoffMethods require the doctor to use a stethoscope to listen to the sound of blood flowing in the blood vessel。The wavefront is measured by measuring the vibration of the blood vessel wall during blood flow.。Although the measurement principle is different，But the test results should be the same in theory.。Different in actual operations due to each doctor's hearing reaction and decrease speed，Korotkoff-SoundMethod is different，Measurement results also generate errors。
Every new product has progressive，however， Only use correctly，Can get the best results。Electronic blood pressure gauge can be divided into upper arm electronic sphygmomanometer， Wrist electronic blood pressure gauge Special sphygmomanometer， And view blood pressure gauges according to different measurement locations。The common market is the upper arm and wrist electronic blood pressure calculations.。
Common precautions for electronic sphygmometers：
1。Before measuring blood pressure，Rest10-15minute，To eliminate fatigue and excitement。Be rest after exercise30minute
2。Indoor environment temperature should be kept20°Cabout； Before measuring blood pressure，Should be carried out3to4Deeper breathing。
3。Lying down, sitting and measuring blood pressure，The blood pressure value is not the same， Measuring the posture of blood pressure must be strictly followed according to the instructions。
4。Emotional tension should be avoided during measurement，Mental disorder，smokes， drink， Before measuring blood pressure，Shower and shower are strictly prohibited。
Wrist sphygmomanometer
It should be used according to the requirements in the manual.，Let wrist stretch45degree。Experiment，When the wrist is rotated outward，Easy to tension and rising blood pressure。Measurement Try the blood pressure gap and the heart at the same level，Do not speak or move during measurement。
Upper arm sphygmomanometer
1。Measuring blood pressure Tropster（Sleeve should be loose，Do not bind blood vessels），Display upper arm，Wrap the sleeve smoothly in the middle of the upper arm（Not the elbow joint）。The lower edge of the cuff is saved from elbow1to2 cm。
2。The tightness of the cuff curling should be able to insert your finger，Tightful blood pressure is low，If the windings are too loose，Then reading too high。Cuffy hose should be placed in the brachial pulse。
3。Sitting in a measurement，not talking，The elbow cannot leave the table，Wrap the sleeve wrapped behind the upper arm， Cuff1/2Keep the same level as the heart。
4。Cuffding Put soft tube And in the right way, you can start the upper arm blood pressure gauge，Blood pressure gauge automatically inflatable，After inflation is stopped， Resting after a period of time，It will start reading，The digital displayed on the screen will fluctuate from high to low，These are normal final， The correct blood pressure value will be displayed。If abnormal blood pressure is found during blood pressure measurement，You should wait for a while to retest。The time interval between the two measurements is not less than3minute，And the measurement position and posture should be consistent。
How to buy a good electronic sphygmomanometer
First choose Brand from professional medical equipment companies to buy products。Most electronic blood pressure gauges produced by these companies have passed the inspection and certification of authoritative certification bodies.。in2002The second quarter of the year， National Quality Supervision The People's Republic of China's inspection and quarantine bureau has conducted a national supervisory spot check on the product quality of electronic sphygmometers.。The pass rate of the electronic sphygmomanometer is100％。should say，At present, the electronic sphygmomanometer in the market is basically qualified.。Ability to measure blood pressure accurately。？
The sphygmomanometer is usually2Until3 mmHg。Buy electronic sphygmomanometer，Take the instructions，Measuring blood pressure can be repeated several times，To see if its repeatability is good，It can be compared to the value measured with mercury blood pressure gauges.。In addition，Check if the number of displayed numbers is lost when blood pressure measurement is measured.。
Compare the measurement results of the electronic sphygmometer with the measurement results of the hospital，View the result of the error。If the error is not too big，Can be used as a reference from me to measure。
Senior patients with severe diabetes， Hyperlipidemia arteriosclerosis，Will cause a surrounding cycle barrier。The blood pressure of these patient wrists is very different from the blood pressure of the upper arm.。It is recommended that these patients and seniors choose toilet electronic sphygmomanometer。
Very fat or very thin man as the circumference of the wrist is not in the range of use of wrist electronic blood pressure gauges，Not suitable for use of wrist electronic blood pressure gauges，instead， Choose an upper arm electronic sphygmomanometer。Time You should choose a wide range of electronic sphygmomanometers。Upper limit is greater than250 mmHg，Lower limit150 mmHg。Regular calibration should be performed using standard blood pressure gauges。Choose memory function as much as possible，Date and time function sphygmomanometer。Some people can remember the blood pressure value of two people, respectively.，If a family, two people share a sphygmomanometer，Very convenient
