4.4.2. Inflating the cuff
Close the air valve on the bulb by turning the screw clock wise.
Do not over-tighten. Squeeze the inflation bulb with the hand at
a steady rate until the pointer on the gauge is 30 mmHg above
your normal systolic pressure value. If you are not sure the
value, inflate to 200 mmHg first.
4.4.3. Systolic blood pressure reading
Slowly open air valve by turning screw counter clockwise and
hold stethoscope chestpiece over brachial artery. Proper de-
flation rate is essential for an accurate reading, so you should
practice and master a recommended defla tion rate of 2 - 3 mmHg
per second or a drop of 1 - 2 marks on the pressure gauge each
heartbeat. You should not keep the cuff inflated any longer
than necessary. As the cuff begins to deflate, you must listen
care fully with the stethoscope. Note the reading on the gauge as
soon as you hear a faint, rhythmic tapping or thumping sounds.
This is the systolic blood pressure reading. Listen care fully and
familiarize yourself with pulse (Korotkoff’s) sound.
4.4.4. Diastolic blood pressure reading
Allow the pressure to continue dropping at the same deflation rate. When your diastolic blood
pressure value reached, the thumping sound stops. Deflate the cuff valve completely. Remove
the cuff from arm and stethoscope from ears.
4.4.5. Record your readings
Repeat the measurement at least two times. Do not forget to record your readings and the time
of the day measurement is made immediately after you finish measuring. A suitable time is first
thing in the morning, or just before evening meals. Remember that your physician is the only
person qualified to analyze your blood pressure.
