How to Measure Blood Pressure

1. Make sure you place the round end of the stethoscope

'under' the blood pressure cuff.

2. Place the diaphragm of stethoscope on the brachial

artery.

3. Inflate the sphygmomanometer (blood pressure cuff) to

a little above 180 mm Hg. This collapses the major

arteries to the arm (that's why it is uncomfortable).

4. Then you slowly release air by gently turning the air

valve, and watch the pressure drop.

5. When you first hear a sound, that will be the Systolic

blood pressure. The sound you hear is the blood now

flowing in the artery of the arm. This means that the

systolic pressure is now greater than the pressure in

the blood pressure cuff.

6. when you no longer hear any sounds, that will

be the Diastolic blood pressure.
