Roll up the sleeve of or take the clothes off from that part of the body which you are using for doing the measurements. For the best possible results make sure the person is sitting upright and the arm should be relaxed.
The inflatable cuff should be wrapped around the arm just above the bend of the arm.
Put the ear pieces of the stethoscope into your ears.
The round side of the stethoscope should be placed just underneath the cuff, on the spot where you can easily feel the brachial artery pulse.
Tightly close the air valve on the bulb. Counter check it for any problems.
The cuff is to be inflated to around 180 mm Hg. You can easily find this reading on the sphygmomanometer.
Now what you have to do is that you have to stop inflating the cuff and make it
deflate instead. For this to happen you will have to turn the air valve so the air
can get out of the cuff.
This is the main task you have to do in order to measure the blood pressure correctly. As the pressure drops there will be a sound, the first sound you hear will be the systolic blood pressure measurement (when the artery is opening). You can note down these measurements either by writing them down
or simply memorizing them.
After this you have to carefully note that where the measurement on the sphygmomanometer is when the last sound you hear takes place. This will be the diastolic blood pressure measurement.
The measurement will be completed by putting the highest number on the top of the lowest
So you don’t have to worry about your blood pressure even if you don’t have an electric blood pressure checking machine.
