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.

Slowly open air valve by turning screw counter clockwise and hold

stethoscope chest piece 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 stethos cope. 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.

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.

☞ 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.
