Sometimes, even a far cry from, which is why?
Basically, there are reasons for the following four points:
First, subjects with no arm and heart on the same general level of online Sphygmomanometer measurement upper extremity (arm about to start measuring the future can be measured right arm), to sitting, feet flat ground, back-back, upper arm bare, the table chair height should be appropriate so that the upper arm at the midpoint of heart level. If excessive arm position, the blood pressure measured value will be low if the arm position is too low, measured the blood pressure will be high.
Second, measurement of blood pressure, such as low mercury played only hit 170 ~ 180 mm mercury column, then although the stethoscope may be silent, but it is likely to heart arrhythmia patients between the two have a longer intermittent.
Third, the pace of deflation is not appropriate in general, the speed of deflated per second mercury dropped 2 to 3 mm appropriate. Deflated too easy to test reaction time and in error; deflated too slowly to the forearm congestion, resulting in higher diastolic blood pressure readings.
4, a test findings may not accurately measure blood pressure should be repeated several times, choose the stable value for the actual blood pressure. Measuring the first time, numerical often high, and second and third generally more stable. Should be deflated after more than 30 seconds rest, then test again. Which is the average of two readings of blood pressure measured.
How to measure blood pressure
Usually mercury sphygmomanometer and auscultation indirect method of Sphygmomanometer measurement, measurement should be quiet before the patients took a comfortable rest for a few minutes, remove tight sleeve clothing, relaxed arm muscles, elbow and forearm support to the high level of the heart (the fourth intercostal Ping) to the appropriate size of the cuff (adults 13-15 cm width between 30-35 cm in length airbag. obesity Application larger cuff, children require smaller cuff) flat tied to the upper arm exposed, inflatable cuff rapid pulse until sphygmomanometer disappeared after reading continues to rise about 4 kPa (30mmHg), and then to about 0.27 kPa (2mmHg) / s speed deflated here with a stethoscope to listen at the brachial artery, I heard the first sound of systolic blood pressure (SBP), voice disappeared or weakened when the diastolic blood pressure (DBP). In no less than three minutes during at least two measurements to calculate its average.
Patients attending for the first time, the proposed measurement sitting and standing, arms blood pressure, such as suspected orthostatic hypotension, should be regularly measured arguments standing blood pressure.
Without some type of device or figures show that the automatic or semi-automatic Sphygmomanometer device to replace the mercury sphygmomanometer blood pressure measurement, it should be noted proofread and check regularly.
Stroke patients with hypertension must be alert
Hypertension is the most common cardiovascular disease. According to statistics, China's hypertension patients have more than 130 million people, over 35 years of age crowd in the prevalence rate of more than 13%, the elderly over 55 years of age prevalence rate as high as 25% -35% in each of the deaths directly hypertension the number of patients over 20 million people. What is more serious is that if no long-term blood pressure can be good control, may also trigger other more serious diseases, the most important of which is recognized around the world led to the death number one killer of the modern "stroke."
Do you really understand hypertension?
China's prevalence rate of hypertension increased significantly to the high incidence of 35-year-old to 74-year-old age group the prevalence rate, and in 2000 China's population and demographic projections, Sphygmomanometer hypertensive patients had reached 130 million, China has become the world's most serious against hypertension countries.
