Measurement of Blood Pressure
Is it true that blood pressure should be a few times to see the real picture? After all, in clinics do not do …
An important indicator of the function of the cardiovascular system, is the level of blood pressure. It is measured mercury sphygmomanometer or a membrane. These devices are in any medical office. If you wish to have a sphygmomanometer at home, you can buy it at the pharmacy.
Self-monitoring of blood pressure, we attach great importance. It is especially useful to the athlete, whose blood pressure increased (or sometimes increase). Note that in the special studies was shown to the temporary increase in blood pressure in patients who have come to the doctor that caused emotional stress. Therefore, now more often encouraged to learn the procedure for measuring the pressure and hold it yourself. This will more accurately characterize the level of blood pressure. With regard to dealing with physical education, then, in our view, conduct self-monitoring of pressure, both at home and during physical education classes is extremely important because it allows us to give a correct estimate of the reactions of the cardiovascular system given by the load and if necessary, to its timely correction. So you can prevent unwanted pathological responses and achieve greater health effect.
The procedure for blood pressure measurement is as follows: the hand is superimposed rubber collar, so it was above the elbow in the 3-4 cm then use a rubber bulb in it is pumped into the air. At the same time on the radial artery (in the wrist area) is controlled by the pulse. After his disappearance, the cuff pressure must be increased by 20-30 mm Hg st. Then
on the ulnar artery (in the elbow closer to the inner edge of it) is set phonendoscope (flexible auditory tube) and slowly decreasing the pressure in the cuff. At that moment, when the blood will reveal still clutched cuff brachial artery, you’ll hear the first pulse tone. Notice for this level of pressure on the scale of sphygmomanometers. This will maximize the value (ie, systolic) blood pressure. Continue on and gradually reduce the pressure in the cuff. Until the moment of disappearance of pulse tones, listen phonendoscope in the elbow, again note the level of pressure. This will be the minimum (diastolic) blood pressure.
The most accurate readings give mercury sphygmomanometers, but recently more widely membrane sphygmomanometers. They are compact, easy to use and reasonably accurate.
When measuring blood pressure is focused only on the audible tones: the emergence of visible to the eye oscillations of the mercury column can not be taken for the time frame of systolic blood pressure, such registration will not be accurate. Register arterial pressure to within 2 mm of mercury Art. (Rounded value should not be). So you do not forget the testimony of blood pressure, write them down immediately.
