1。 What should I pay attention to when measuring blood pressure?？
One day blood pressure is normal，Different situations Different mental conditions and different postures，Blood pressure may be different。therefore，Measuring blood pressure，Please pay attention to the following points：
（a）Before measuring blood pressure，Sitting in a quiet spirit。
（b）Motion pressure can not be measured immediately after emotional tension and excitement。
（c）Stroven blood pressure cannot be measured immediately after exercise and working。
（d）Sit straight during measurement，Take a sleeve of jacket，Do not roll tight sleeves，Place the arms palm to the upper arm and the heart in the same level，Muscle should relax。If it is horizontal while keeping the upper arm and the heart at the same level，It can't be too high or too low。
（e）Don't be nervous when measuring blood pressure，Don't breathe, because the breathing can cause rising blood pressure。
（f）The cold environment will increase blood pressure； High temperature environments reduce blood pressure，Pay attention to this。
2。 Why can't you open it?？
Whether inserting a battery？Is the battery dead?？Whether the battery direction is wrong？
3。 Relationship between electronic sphygmomanometer and medical mercury sphygmomanometer
Mercury sphygmomanometerKorotkoffmethod。 Electronic sphygmomanometer， Corioli（Coriolis）Methods Use a stethoscope to listen to the sound of blood flowing in the blood vessel。 Excluding the vibration of the blood vessel wall during blood flow。 Although the measurement principle is different， But the test results are theoretically the same.。In fact， Since each doctor's listening speed is different， Corioli Method sometimes records blood pressure reading immediately during the measurement process，And the error is large。therefore， Each doctor's measurement also generates an error。 Electronic 易彤破壁机维修点 sphygmomanometer eliminates the difference between people and people， Doctors usually ignore some mistakes and rounded。 E.g：128mmHg， 131mmHg， Doctor read it for130mmHg。Electronic sphygmomanometer shows the value of its measurement。 There are also user feedback， Always very low when you measure， I went to the hospital blood pressure. This is called white high blood pressure。 Means of， In front of the doctor in the hospital， Unconsciously generate a certain degree of anxiety， Nervous and mental stress， Blood pressure rise And relax at home The lower the blood pressure This is the true reflection of human blood pressure。
The above phenomenon is combined， Give people an electronic sphygmomanometer，It does not match the blood pressure measured by the doctor。 And the impression of the electronic sphygmomanometer is 易彤破壁机售后网点 inaccurate。in fact， According to rules， Before obtaining production license， Electronic sphygmomanometer must be clinically trial。
4。 Why is the arm blood pressure ratio to wrist blood pressure?？
Many hypertensive patients choose electronic blood pressure gauges to monitor blood pressure daily，So, which electronic sphygmomanometer is more suitable for you?？
Three types of electronic blood pressure pressure：Finger clip， Wrist and arms。Everyone has its own instructions，But the arms should be the first choice for accuracy.。Finger pointing electronic sphygmomanometer mainly measuring blood pressure of the peripheral artery。Doctors usually use it to monitor blood pressure during surgery。This sphygmomanometer measures the end blood pressure，The result is not very accurate。
Monitor blood pressure in patients with hypertension，Don't consider this sphygmomanometer。Wrist Electronic Blood Pressure MeasurementtheArtery pressure，Also belong to the end of blood pressure，therefore， The pressure measurement results are not as accurate as the arm sphygmomanometer。Due to wrist electronic blood pressure gauges easy to use，Can measure it at any time， Compare the office worker People who often travel or measure multiple patients every day。
Arm sphygmomanometer mainly measures the radial pressure of the upper limb。It also measures heart rate，It is more accurate than wrist and finger clip sphygmomanometer。Recommended ordinary patient， Especially those who are weaker Low blood pressure， And malignant hypertension， Use arm type electronic blood pressure calculation。Otherwise it is easy to cause measurement errors。
Hard pressure gauges can measure blood pressure more accurately，More simple and easy to operate。
5， What is wrong with blood glucose meter?？
Internationally Blood glucose meter error20％Within。Our products are in10％Within。
6。 After inserting the settings check card， The display appears on the display“ E-C”still is“ E-b”？
“ E-C”Set check card is corrupted， “ E-b”Indicates too low the voltage，Replace the battery in time。
7。 Why do you measure blood glucose measured in your home?？
（1）Different blood samples extracted by both。Blood glucose meter from finger blood，It is obtained that the glucose content in capillary blood is； Hospital biochemical instruments are extracted from venous blood。Detected is the glucose content in venous plasma。usually，The two are too close to the stomach.，Human plasma blood glucose level is higher than capillary blood sugar levels after meals10％?15％。
（2）Irregular operation。Alcohol for disinfection skin must be completely evaporated，Then you can blood!。Because the least amount of alcohol on the skin affects the results of the measurement。The patient's self-test blood sugar is sometimes not good enough，Pick the blood first before the alcohol is turned，The result of this test is not accurate； In addition，Some patients are afraid of pain，therefore，Adjust the depth of the thorn blood，Insufficient blood，The result of the examination is not accurate；When some patients see the blood volume is insufficient，Just crowded with your fingers，Since the blood is placed in the blood in the blood contains tissue fluid，at this time， Measurement is lower or not allowed。In addition， Do not comply with the instructions， The failure of moisture or test parts affects the test results。
（3）Different measurement time，So there is no comparison。Human blood sugar every day24Hourly changing，Will be affected by changes in its own hormones， mood， diet， Sports and other factors。and so，The results of different tests cannot be compared at the same time。
