How To Check Blood Pressure With A Sphygmomanometer?

If you think that you are experiencing the ‘symptoms’ of hypertension, you need to be careful about this and take the necessary actions quickly. One important thing to do is to monitor your blood pressure each day on an accurate basis. Popularly used device to measure blood pressure is the manual one which is known to everybody as the sphygmomanometer. This monitor functions with the mercury as a gauge which indicates the readings when the arm is being compressed by the use of a cuff.

How To Check Blood Pressure With A Sphygmomanometer ?

The following tips can be helpful:

First, the device should be placed on a flat surface. A coffee or side table will be perfect.

The blood pressure meter lid should be opened and the lower part must be positioned upright.

A steel lever is located on the bottom part of the machine, locking the mercury in its position

when the monitor is idle. Also, the lock prevents the device from breaking and possible damage.

However, this should be unlocked to release the hold on mercury which will escalate a little bit

of this movement.

The rubber pipe should be attached to both ends of the cuff and the pressure strap as well as on

the BP monitor on the other hand.

Use your left arm for the cuff half an inch just beyond your elbow. You can also use your right

arm but be sure to record this on your notes.

If you noticed that the strap has a Velcro, just stick the opposite ends. If a hook is present, find

an edge and simply tuck it in.

Remember to strap your arm with the right pressure. Too loose or too tight can make the

readings inaccurate.

Getting your readings

After you had set up your BP device, you are now ready to measure your blood pressure. Check on the

following procedures for you to properly get the readings:

Use the stethoscope and place them properly on your ears. The other end should be stuck in the

strap. Listen intently for the first rush of the pulse that rushes through the arteries of the arms.

Before doing this, make sure you are in a quiet place so that you can hear the beating of the

blood clearly.

Pump adequate amount of air in the strap in for the bulb to function properly. Tighten the screw

to guarantee air won’t leak.

Continue pumping until you see the mercury going above the 30mm, after which you can

now hear complete silence for a couple of seconds. Note that it should be slightly beyond the

supposed diastolic pressure.

Loosen the screw gradually until the air starts to flow slowly. Again, listen cautiously and watch

till the mercury begins to lower.

A sound of blood rushing though the veins can be heard and becomes noticeably loud as the

flow of blood rises. A record that point which you heard is the strongest; that will be your systolic


Once again, listen to the sound till it fades slowly. You will notice that there will be a point when

you cannot hear anything anymore. Check on the numbers quickly because this will be your

diastolic pressure.

Blood pressure measurement should be done twice or even thrice each day for an accurate basis of

diagnosis. Bring the record to your trusted doctor.
