4.5.3. Systolic blood pressure reading

Slightly and repeatedly push button of the valve and 
hold stethoscope chestpiece over brachial artery. Proper 
deflation rate is essential for an accurate reading, so you 
should practice and master a recommended deflation rate 
of 2 - 3 mmHg per second or a drop of one to two 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 carefully 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 carefully and 
familiarize yourself with pulse (Korotkoff’s) sound. 

4.5.4. 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. 

4.5.5. 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.

Further information

Measurements should not occur soon after each other, since otherwise, the results will be 
falsified. Wait therefore for several minutes in a relaxed position, sitting or lying, before you 
repeat a measurement.
