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.
