1.1 About blood pressure
Blood pressure is the mechanical pressure exerted by blood on the
inner surface of arterial blood vessels. It is measured in millimeters
of mercury. Blood pressure of a human is not constant over 24 hours,
but fluctuates within the certain range. There are two components
of blood pressure:
Systolic blood pressure is the value of blood pressure that occurs
in arteries in the moment of contraction and ejection of blood from
the left ventricle into circulation.
Diastolic blood pressure refers to pressure in arteries in the moment
of ventricular relaxation.

1.2 Blood pressure disorders
High blood pressure (Arterial hypertension) is defined as a condi-
tion in which either both or one component of blood pressure are
elevated above the values referred to as referent ones(Table 1).
A good control of blood pressure requires repeated blood pressure
measurements at few days’ intervals, which can be performed at your
doctor’s office or out of it. Elevated blood pressure values are often
without symptoms, which can result in a delayed diagnosis. If elevated
blood pressure values persist over prolonged period of time, they
can cause numerous complications in target organs, such as heart,
brain, and kidneys. A better control of blood pressure may reduce
the risk form sudden cardiovascular and cerebrovascular events.
Regular measurement of blood pressure is beneficial for diagnosis,
as well as for therapy control. High blood pressure in pregnancy rep-
resents a particular problem, which requires a regular monitoring
with a constant consultation with physician.
Low blood pressure (Arterial hypotension) is a condition in which
either both or one component of blood pressure are lowered bel-
low expected values. Regular monitoring of blood pressure is ben-
eficial not only for diagnosis of hypertension, but also for diagnosis
of hypotension. Hypotension may cause dizziness and loss of con-
sciousness particularly in elderly who experience deterioration of
autonomous nervous system functions during standing, after meals,
or after having bath.
1.3 Proper measurement of blood pressure
Indirect methods for measurement of blood pressure was introduced
by Korotkoff in 1905. It is still used without major modifications.
Blood pressure is measured in sitting position. Cuff should be wrapped
around upper arm, so that its edge is positioned 2 cm above the cu-
bital fossa (elbow pit). Palpate radial pulse, inflate the cuff quickly
up to 70 mmHg, and later on gradually. Note the level of pressure in
which pulse dissapears when blood vessel is completely compressed,
PA1

and inflate cuff additionally 30 mmHg above that value. Position the
chestpiece on the spot palpated above the brachial artery. Release
the air from the cuff at speed of 2-3 mmHg per second. Once the
systolic pressure is equalized with the pressure in the cuff, the first
sounds are audible (so called Korotkoff sounds). In the moment when
they completely disappear, diastolic pressure is equalized with the
pressure in the cuff, and blood flow is again uniform. Auscultation of
those sounds is conducted in five phases, and occurrence of the first
phase that marks appearance of the sounds corresponds to value of
systolic pressure, while occurrence of the fifth phase, when sounds
disappear, represents the value of diastolic pressure.
Measurement should be repeated after half of an hour, and then
mean value of both measurements should be calculated.
Note:
•
In children, age 4 to 12, value of diastolic blood pressure is read
in the fourth phase. The fourth phase of sounds auscultation
marks transition from a clear sound to a muffled one.
•
In pregnant women, value of diastolic blood pressure is read in
the fifth phase, except in the case when air from the cuff is re-
leased and sounds are still audible, and then blood pressure is
read in the fourth phase.
1.4 About aneroid blood pressure measuring device
PA1 is an aneroid device for accurate and precise measurement of
blood pressure using manometer (pressure gauge) with a pump,
cuff and stethoscope. Measured values are read on the large and
clearly visible manometer’s scale. It is suitable for professional use
in hospitals, offices, ambulances, as well as for use in home envi-
ronment (with an adequate training and provided that instruction
for use is carefully read). A special ergonomic design allows a simple
and comfortable use with both left and the right hand. PA1 contains
a predefined cuff that allows a larger contact area, proper position-
ing and comfort. Larger contact area allows a higher reliability of the
device during blood pressure measurement.

sure, avoid physical activity, alcohol, caffeine, cigarettes, and do not
take a bath or eat for 30 minutes before taking a measurement.
Prepare the PA1 device. Attach the air hose from the cuff to air hose
connector on manometer (Figure 1).
4.2 Body position during measurement
Proper body position during measurement is necessary in order to
obtain accurate results (Figure 2).
Note:
•
Measurements should be taken in a quiet place, in relaxed, sit-
ting position. Take a measurement at room temperature.
•
Do not move or talk during measurement.
4. Using The Product
Figure 2
Proper
body
position
Place your arm on the table, so the
cuff is at the same level with your
heart.
The distance between the chair
and the top of the table should
be between 25 and 30 cm.
Sit upright
with the
straight back.
Remove clothing that constricts your
upper arm, as well as any piece of a
thick clothing, such as sweaters. Do
not place the cuff over a thick clothing
or roll up your sleeve if it constricts
your arm and upper arm.
PA1

Measurements can be taken on the left or the right arm. Blood pres-
sure may be different between the left and the right arm, hence,
blood pressure measurement readings may differ between arms. It
is recommended to take measurements on the same arm, in order
for results to be comparable. If measurement values between arms
are significantly different, consult your doctor to verify which arm
should be used for measurements.
Incorrect body position:
•
Hunched back (bent forward)
•
Sitting with your legs crossed
•
Sitting on a sofa or a low table, leaning forward.
Such situations may cause high blood pressure values due to strain
or the cuff being positioned billow your heart level. If the cuff is po-
sitioned bellow your heart level, use pillows and adjust the height
of your arm.
4.3 Placing the cuff
Bare your upper arm.
Caution: If you roll up your sleeve, ensure that it is not too tight be-
cause it may disrupt the blood circulation.
During blood pressure measurements, cuff has to be wrapped around
upper arm, so that its lower edge is positioned 2 cm above the cubital
fossa (elbow pit). PA1 has a preformed cuff that follows the shape of
Instruction Manual
14
your arm, so it is sufficient to wrap the cuff around your upper arm
and slightly tighten it. Place the cuff positioning the mark for artery
in the middle of your upper arm. Air hose should lay along the inner
side of the forearm. It is also possible to measure blood pressure on
the right upper arm.
Note:
•
When you take measurements
on your right arm, air hose will
be located on the outer side of
your upper arm. Be careful not to lower your arm on the air hose
during measurement.
•
Blood pressure may be different between the left and the right
arm, and that is why measured blood pressure values may dif-
fer between arms. PRIZMA recommends that you always use
the same arm to take measurements.
4.4 Taking a Measurement
During blood pressure measurement with an aneroid device, after
proper body positioning and cuff placement, take the following steps:
•
Verify that arrow on the manometer scale is located within the
framed field while the air exhaust valve is opened (Figure 3)
•
Palpate the radial pulse
•
Close the air exhaust valve by moving your thumb up, towards
manometer (Figure 3)
•
Inflate the cuff by pressing the rubber bulb (pump) up to value
that is 30 mmHg higher than expected one
•
Place the chestpiece of the stethoscope on the palpated spot,
and insert eartips into your ear canals
•
Slowly open air exhaust valve by moving your thumb towards
the air pump (Figure 3), so that speed of air release is 23 mmHg
per second, which could be verified by monitoring arrow on the
manometer scale
PA1
Aneroid blood pressure measuring device
15
•
Listen for sounds appearance and monitor values indicated by
arrow on the manometer scale
•
Once the first sound appears, check the value indicated by ar-
row on the manometer scale. That sound corresponds to sys-
tolic blood pressure
•
While sounds disappear, check the value indicated by arrow on
the manometer scale at the moment when the last sound is
barely audible That sound corresponds to diastolic blood pres-
sure
Measured blood pressure values should be interpreted only by a
qualified physician.
Note:
•
Take a break of at least 5 minutes between repeated blood pres-
sure measurements.
