How to Take BLOOD
PRESSURE MEASUREMENT
To take the reading, follow these steps:
1. Leaving the Cuff's lower edge about
an inch above the bend of the elbow, place the cuff over your bare arm, close
the cuff around the arm, and then stick the Velcro together at the ends of the Cuff.
2. Place the earpieces of the
stethoscope in your ears and place the stethoscope bell at the side of the cuff
away from your heart and over the brachial artery, which is found in the inner
area of your bent elbow.
The Stethoscope is a convenient measure device for listening sounds the various sites,has a point of contact known as the stethoscope's Bell. The two earpieces at the other end of the stethoscope enable to hear the "steady" -within the normal rate-, a Thump in the brachial artery.

3. Tighten the screw at the side of the
rubber bulb and squeeze the bulb.
Air is pumped into the
bulb, and thus the cuff expands.
4. The Cuff is inflated until the blood
flow through your brachial artery stops.
With sufficient compression, the cuff cuts off blood flow through
the artery, and no sound is heard in the stethoscope. The pressure in the cuff
is increased rapidly to 30 millimeters of mercury above the point that no blood
flow is taking place through the cuff when no sound can be heard in the
stethoscope or when a pulse can no longer be felt in the wrist.
5. Turn the screw again to loosen the
valve in the bulb and to lessen the air pressure.
Pressure is then decreased so that the rate of drop is 2
millimeters per second. When the pressure falls to the point that blood begins
to flow through the artery again, the number that the column of mercury has
risen to at the first sound heard in the stethoscope is the systolic blood
pressure (SBP), the first number in the blood pressure reading.
6. Look at the column of mercury to see the number at that
pressure point.
7. When the Cuff decompresses to the
point that blood flows freely in the artery, the sound is no longer heard in
the stethoscope.
The number next to the top of the column of mercury when the sound
ceases is the diastolic blood pressure (DBP), the second number in the blood
pressure reading.
8. Again, look at the column of mercury
to see the number at that pressure point.
