1. POSITION THE PRESSURE CUFF
Practice the following procedure several times to become familiar with the equipment. Before taking your
blood pressure, plan to relax and rest for at least 15 minutes. This will reduce the error due to physical
activity. If you are right-handed, slip the pressure cuff over your left arm and extent your left arm palm
up. Whether sitting or lying, be sure that your arm rests at the same level as your heart. Turn the cuff so
that the stethoscope diaphragm (sound head) is on the inside of the arm just above the elbow. This
locates it over the large artery near the hollow of the elbow. (This artery can be also found by feeling for
the pulse of the artery) Grasp the end of the cuff and pull it snug, then wrap it around and over your arm,
pressing together with Velcro tape to bin the cuff securely
2. INFLATE THE CUFF
Feel the pulse of the artery with your fingertips to be sure the heads of the stethoscope is located
directly over it. Insert the earpieces of the stethoscope (adjust by turning earpieces to fit comfortably in
your ears) Hold the gauge in your left hand or clip onto the cuff on the loop provided for feading. Close
the airflow valve on the bulb (turn clockwise) DO NOT OVER TIGHTEN. Inflate the cuff by repeatedly
squeezing the bulb with your right hand. Listen to the pulse beat whilst inflating the cuff. Watch the
gauge. When you can no longer hear the pulse beat. Raise the pressure an additional 30 mm.
3. SLOWLY DEFLATE THE CUFF
Slowly open the airflow valve by turning counter clockwise so that the pressure drops 2-4 mm Hg with
each beat of your heart. (This will usually mean a drop of one to two marks on the gauge every second)
The rate of deflation is important for accurate reading. Remember tie pressure of the cuff bas shut off all
blood, flow to the arm. So do not leave it inflated fully any loner than absolutely necessary
4. SYSTOLIC PRESSURE
After opening the airflow valve, listen carefully for a pulse beat. The moment you hear the faint rhythmic
tapping or tumping sound of the pulse beat, note the reading on the gauge. This is your systolic (upper)
blood pressure. It may be difficult at first for you to detect the sounds of the pulse beat, listen carefully
and acquaint yourself with these unfamiliar sounds .You should also notice the needle on the gauge
"bounce” when your systolic pressure is reached.
5. DIASTOLIC PRESSURE
Allow the pressure to continue dropping at the same rate as be- for 2-4mm Hg per second. Listen
carefully with the stethoscope. The sounds you hear will change the phases. From the first sharp tagging
or thud, they will soften to blowing or swishing sounds Watch the felling needle. At the exact point when
you can no longer hear the sounds, read the gauge. This is your diastolic (lower) blood pressure
reading.
6. NOTICE
With proper care your blood pressure Monitor will provide many years of reliable service. To insure a
well functioning unit, follow these basic rules:
•
Pressure gauge should be handled with care, do not drop or jar
•
Needle should indicate zero when cuff is fully deflated.
•
Under normal condition, the device is recommended to be calibrated every two years and after repair
•
Calibration should be carried out at the points of 50 mmHg and 200
