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.
