1, the room should be kept quite when pressure reading. The room temperature is better keep at about 20℃.

2, people should be relaxed and it is better rest for 20-30 minutes before measured. Empty your bladder, don’t drink wine coffee and strong tee, and stop smoking.

3, patients can choose to sit or lying with both feet flatwise. And patients’ elbow and forearm should keep parallel with their heart comfortably.

4, keep the mercury column to zero vertically and put the blood pressure monitor near patients stably.

5, ask the patients take off clothes and show their right forearm. If patients wear wide sleeves, they can roll up the sleeves to armpit.

6, before wind air cell, you should fume-off vent gas in it. After that, wind air cell around the elbow joint on the right upper arm 2 to 3 cm, not too loose or too tight. When you feel brachial artery’s beating at armpit, put the stethoscope on brachial artery, and then pump to measure patients’ blood pressure.

7, close the valve to check the height of the mercury column. Please remember that measurer’s sight should be kept parallel with degree of the mercury column. Fast filling and tactile radial pulse compression, then disappeared 4kPa (30mmHg) can stop inflatable, micro-gas valve open, so that the mercury slowly down, when the first tone when the sound pulse, “high-pressure “, that is, systolic blood pressure. Continue to slightly deflated, mercury slowly down to a certain scale of mercury, voice suddenly become weak or disappear as “low”, namely, diastolic pressure.

8, air should be completely deflated after the first measure. After at least one minute, measure again and then take the average of two measures. In addition, if you want to determine whether suffering from hypertension, even the best in different time, generally, at least three different days I can measure blood pressure value as hypertension.

9, arrange the air cell, stethoscope and resume the mercury column to zero.

In humans, normally the cuff is placed smoothly and snugly around an upper arm. Other sites of placement depend on species, and may include the tongue, flipper, tail or teat. The correct size of cuff selected for the patient is essential. If a cuff is too small, the results will be too high a pressure, otherwise, if too large, will be too low pressure. The cuff is inflated until the artery is completely occluded. Listening with a stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff.

The pressure at which this sound began is noted and recorded as the systolic blood pressure. The cuff pressure is further released until the sound can no longer be heard. This is recorded as the diastolic blood pressure. In noisy environments where auscultation is impossible, systolic blood pressure alone may be read by releasing the pressure until a radial pulse is palpated. In veterinary medicine, auscultation is rarely of use, and palpation or visualization of pulse distal to the sphygmomanometer is used to detect systolic pressure.

There are three types of Blood Pressure Monitor:

1, Digital with manual or automatic inflation. They are electronic, easy to operate, and practical in noisy environments.

2, Digital portable finger blood pressure monitors with automatic inflation. These are more portable and easy to operate, although less accurate.

3, Manual
