Taking Your own Blood Pressure

Taking your own blood pressure can be an important part of your general health care.
Frequent and reliable measurements of blood pressure are the best means of detecting
the onset of high blood pressure and for determining the effectiveness of any treatment
program.

Your physician has probably given you some instruction in the use of this device, but
sometimes it is hard to remember everything the doctor has told you.

To help you use the unit most effectively, we have prepared this booklet which will
familiarize you with the equipment and prepare you to take your blood pressure easily,
reliably, and safely.

Read this booklet carefully before you attempt to use this device. Consult your physician
for additional instructions, if necessary.

Let’s Look At This Device

This device is called a sphygmomanometer (sfig-mo-man-om-eter) or simply, sphyg for
short.

This sphyg has three basic parts:
an inflatable cuff, a pressure gauge combined with an inflation bulb and valve, and a

stethoscope.

The Cuff

The cuff is a fabric band that wraps around your arm. It has a metal D-ring on one end
and hook and loop fasteners to allow easy one hand size adjustment. Inside the cuff is
an air tight rubber bladder. This bladder receives the air that creates the constricting
force on the arm necessary for blood pressure measurement. The tube of the bladder
connects directly to the pressure gauge. The stethoscope chest piece is attached
directly to the cuff to help insure that blood pressure sound will be heard clearly and
accurately.

The Gauge And Inflation Bulb

The gauge you have purchased is an aneroid device
which utilizes a mechanical system to measure
pressure. It features a circular dial face which measures
from 0 to 300 millimeters of mercury (mmHg). mmHg is
the standard unit of measurement for blood pressure.
The gauge is a durable product, but should be handled
carefully and not dropped.

The inflation bulb is used to pressurize the cuff. This is
done by squeezing the bulb quickly and repeatedly until
the desired level of pressure is desired.

Above the inflation bulb is a trigger release valve which
allows you to deflate air from the cuff at a slow and
even rate. The trigger is utilized in the “out” or “pump”
position when inflating the cuff. When the measurement
is complete, the trigger can be locked down into the
“dump” position for complete deflation of the cuff.
