Blood pressure stethoscope and sphygmomanometer needs. The device is currently used for Hg, pneumatic and electronic three-and-device used to Hg is most common.
Measurement, the measurement should rest quietly for five minutes to eliminate tension, fatigue effects on blood pressure. Subjects were admitted to sitting or supine position may be, measured by the arm and right atrium should be placed on the same level (sitting with the arm when the fourth costal cartilage on Neurological Hammer the same level, when lying on the center line of axillary), and outreach 45 degrees. Volume on the sleeves to be axillary, or take off the side of sleeves, to facilitate the measurement.
Blood pressure, should be the first device cuff gas emptying, and then the cuff formation in the upper arm to tie up, not too loose or too tight, so as not to affect the accuracy of measurement. Central air bags in front of the elbow Waterloo brachial artery, the cuff edge of Waterloo elbow from 2 to 3 centimeters. Open slot mercury switch.
To find out the middle finger and index finger of the brachial artery pulse, stethoscope of the chest (that is, the round-stethoscope) in the brachial artery Neurological Hammer pulsatility the most part, and work closely with the skin of the paste, lightly pressure, with his left hand fixed. Sphygmomanometer right hand grip of the balloon, to close the valve on the balloon to bolster the cuff, repeatedly, until the brachial artery of the pulse disappeared, let Hg increase 20 to 30 millimeters, you can open slightly rotary valves, the release sleeve With the gas, Hg uniform slow decline in attention to the changes in sound and Hg on the scale.
When I hear the beep, Hg indicative of a few cents is the systolic pressure when the sound suddenly weakened, the directions mm Hg diastolic blood pressure. If no Listen, should first put the cuff End of the gas so that the mercury dropped to zero, pause a moment and then repeated measurements, mind-measured value.
Measurement should be finished emptying the cuff, gas, Neurological Hammer tightening valves screw cap, untie the cuff, will be folded neatly and balloons placed in the box, close the trough of mercury switches, to prevent backflow of mercury. Finally the lid off the device.
If you need daily observation of changes in blood pressure, should be at the same time, the same position, with the same measurements Sphygmomanometer the same side of the arm blood pressure, the results of this test was more reliable. Patients with better economic conditions, the market can now buy the electronic device, it's very convenient to use.
