Electronic blood pressure meter.
Electronic blood pressure monitor has just entered China, into the family, due to its novelty, in use process often happen some misunderstanding, it is recommended to use before you carefully read the instructions and pay attention to the following points:
A what is blood pressure? Have high blood pressure how to do?
Blood pressure is the human body blood on the wall pressure diastolic pressure called the diastolic blood pressure, the normal value of 60-90mmHg. systolic pressure called the systolic pressure, normal values for 90-120mmHg.40 years after each increase of ten years of age can relax 10mmHg.
If you have hypertension, also do not be nervous, attention to diet. Tai Chi exercise; and pay attention to regular medication, his best with a sphygmomanometer, in order to monitor blood pressure and hypertension medication effects. In conditioning, three pills, seven points to regulate, and pay attention to the prevention, nip in the the bud. According to an authoritative survey, cardiovascular and cerebrovascular disease prevention of a dollar can save 8.59 yuan for medical expenses . And the corresponding end save costs can save more than one hundred yuan, the cardiovascular and cerebrovascular diseases should be on prevention.
Two. Pressure is a " fluctuation " or a " constant "?
Because of the blood is liquid, so the " pressure " with a variety of factors " wave ", can be emotional factors . Sports and other conditions, but this " fluctuation " in a relatively fixed scope changes, such as not " originating coronal ." " violent movement " and other special cases are generally not " tempestuous waves " fluctuation, will only belong to " be in a calm mood " of " be in smooth water " small fluctuations, with daily life. Season. Sooner or later, and other factors, its change value generally about 15mm-20mmHg. The blood pressure in the normal range of fluctuations are " physiological " phenomenon . Such as day of blood pressure values connected should there is a rugged full of vitality " curve ", rather than the rigid " straight line ".
Three - electronic sphygmomanometer has several, each of which features?
According to the measuring site division, can be divided into the wrist and arm type, according to the measurement methods of automatic and semi-automatic.
In general, the arm type use method is simple, easy to use, less error, but winter clothes is not convenient, if separated by clothes more, there will be errors on accuracy . On the other arm subcutaneous fat thickness, strapped cuff can not be too tight or too loose, strapped cuff band, inflatable can hold a finger the gap is better.
Wrist type in use should pay attention to its and heart are on the same side, each high or low 1CM, have about 0.8mmHg error, please strictly in accordance with the specifications or professional guidance recommends the use of methods to measure, but is more convenient, do not need to take off his clothes, but for some people ( about five percent ), because of its blood viscosity is high, poor microcirculation and other factors ( such as diabetes, arteriosclerosis and so on ), the numerical and arm type method is sometimes in more than 10mmHg. This part do not use the wrist type, or the user himself that the wrist and arm measured by the measuring value gap, do your know the score, so that reference.
In short, no matter what kind of blood pressure, have fixed time, posture. Methods. Ipsilateral measurement, are " comparable degrees ."
Four - electronic sphygmomanometers accurate?
Electronic sphygmomanometer in China is the State Pharmaceutical Administration of registration management of two types of medical equipment products, with the United States Hypertension League International BGS certification, American Medical Association AAMI certification, the German Hypertension League GS who. For its scientific accuracy, not doubt, in the same hospital, medical center has been widely used electronic blood pressure meter, a mercury sphygmomanometer in consideration of mercury leakage pollution of the environment has been eliminated . Electronic sphygmomanometer in Euramerican developed country is generally by and use the product.
For accuracy without reason is suspected, only understanding its several features, and proper use and understanding of blood pressure knowledge, these products in the market have after medical experts extremely strict " test".
In fact, in the strict sense of the " accuracy ", electronic blood pressure monitor more than ordinary mercury sphygmomanometer, because Mercury Sphygmomanometer measurement can not rule out the possibility of each physician's listening " error ". " Visual error ." " error in judgement ", so the general reading " approximation " method, which using a mercury sphygmomanometer measurement it generally only " integer " . And electronic sphygmomanometer excluded between people and these errors, as in the use of electronic sphygmomanometer measurement
88.89.91.92 this value such as using a mercury sphygmomanometer with a physician to rule out the possibility of " listening error ." " visual error ." " error in judgement " circumstances beyond, its will only take approximate value " 90 " this figure, so in this case, " know" the patient will think electronic sphygmomanometer "no mistake ." more important is if it is " 87 ", " number ", for this fleeting changes, it may read " 85 " may also read " 90 ." informed insiders think is it right??
In China, blood pressure diagnosis experience: the pulse ( heart, a difficult, such as string pulse, tight pulse is very subjective feeling ) - mercury sphygmomanometer (presence of mercury spills, along with environmental protection consciousness strengthens gradually, will be eliminated ) - electronic sphygmomanometer development direction.
Five. Pay attention to blood pressure measurement two phenomena: " white effect." " blood pressure malaise ."
1 " white effect ":
Some people to the hospital when measuring high than at home, this is often due to motion. The unconscious nervous factors.
2 " blood pressure malaise ":
Self testing blood pressure is good, but some people into a " overcorrect " error, such as someone to measure blood pressure high emotional tension and anxiety, often another test will be higher, and fall more measure more vicious spiral, or some continuous measurement of blood pressure, vascular repeated compression, often meet again the measured larger fluctuated " wave ", the wave motion brings new irritability and restlessness, even one day a dozen times measured continually, this phenomenon is called " blood pressure malaise ."
We should have a correct understanding of blood pressure knowledge, if repeated measurements, each measurement interval of less than 3 minutes, and in the measurement of gas pressure in the past before discharge, and grasped by hands several times, in order to facilitate the restoration of vascular.
For " blood pressure malaise " that people put forward two suggestions A. correct understanding of blood pressure knowledge, on blood pressure in normal physiological " fluctuation " to understand: B. if the blood pressure knowledge understanding ability is poorer, in can't get rid of: blood pressure malaise " situation, only using the mercury sphygmomanometer, its the results and the ordinary mercury sphygmomanometer is more rough, sometimes " woolly-headed " but will make a part too " careful " people at ease, or it will fall into the " tight blood pressure fluctuation of blood pressure fluctuation is bigger, more intense strange circle " (which some people do not use the best wrist sphygmomanometer, because it is more difficult to master ).
Six. Why hospitals are not in common use " electronic sphygmomanometer "
Currently in the country with the exception of a few large formal examination center. Sino-foreign joint ventures with the use of the electronic sphygmomanometer, in general hospitals rarely seen " electronic sphygmomanometer disappeared ."
Electronic blood pressure meter is currently a few major import brands, prices generally higher, if a hospital for electronic sphygmomanometer, the hospital is also not a small expenditure.
Today with the exception of a few countries in Europe and America considering the mercury sphygmomanometer leakage and environmental pollution, and banned the use of mercury sphygmomanometer, in China also did not consider the situation. So the economic basis and environmental awareness, is also an important reason.
The hospital is, in consideration of economic factors and do not consider the environmental awareness of the situation, the current must be using a mercury sphygmomanometer, simply because the accuracy, the regular doctor using a mercury sphygmomanometer and an electronic blood pressure monitor are the same.
Medical profession master, cardiovascular and cerebrovascular disease expert Professor Hong Zhaoguang in his monograph " let the health with you a Book page on P192-194 electronic sphygmomanometer. Mercury sphygmomanometer is relatively fair. Objective evaluation.
In short, the electronic sphygmomanometer is a hi-tech product, development of science and technology today and medical union product, from development to promote, in each state has a very strict requirements, in China as in regular medical equipment management, so the accuracy of no problem, therefore, we can be assured use, this is modern science and culture brought to our results, we should enjoy the achievement, and the understanding of blood pressure in the common sense, to the scientific management of our health
