GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and effec-
tive operation of the Device for measurement of blood pressure (hereinaf-
ter – the “Device”). Use this Device according to the rules described in this
Manual. Operate the Device only as intended. Do not use the Device for
any other purposes. Read and understand the whole Instruction Manual,
in particular «RECOMMENDATIONS ON CORRECT MEASUREMENT».
INDICATIONS FOR USE
The device is designed to measure arterial pressure of human according to
Korotkov method. The device is recommended for use under conditions of clin-
ics and hospitals, as well as in household conditions as supplement to medical
observation.
Pressure is measured by means of auscultation of Korotkov’s tones by stetho-
scope and by taking readings on manometer.
RECOMMENDATIONS ON CORRECT MEASUREMENTS
1. Do not use the device without preliminary consultation with Your doctor,
if You undergo treatment by hemodialysis or by anticoagulants, antithrombo-
cytes or steroids. Use of device in these cases may cause internal hemorrhage.
2 . For correct measurement you should know that THE BLOOD PRESSURE IS
SUBJECT TO SHARP VARIATIONS EVEN WITHIN THE SHORT TIME INTERVALS.
The blood pressure depends on many factors. It is usually lower in summer
and higher in winter. The blood pressure varies together with the atmospheric
pressure, depends on physical loads, emotional excitement, stresses and di-
etary regime. Drugs, drinking alcohol and smoking produce significant effect.
Even the very procedure of blood pressure measurement in a polyclinic sends
the blood pressure high in many people, thus, the blood pressure measured at
home often differs from the values received in a polyclinic. As the blood pres-
sure tends to rise at low temperatures, make measurements at an indoor tem-
perature (approximately 20°C). If this Device stayed under a low temperature,
keep it for at least 1 hour at an indoor temperature before use, otherwise the
measurement result may be incorrect.
During a day the difference in readings for healthy people may be 30-50
mmHg of systolic pressure and to 10 mmHg of diastolic pressure. The depen-
dence of the blood pressure on various factors is individual for each person.
Accordingly, it is recommended to keep a special book with blood pressure
records.
ONLY A CERTIFIED DOCTOR USING YOUR RECORDS IS CAPABLE TO
ANALYZE THETENDENCY OF YOUR BLOOD PRESSURE VARIATIONS.

ENG
3. At cardiovascular and some other diseases requiring blood pressure monitoring
make measurements in the hours fixed by your attending doctor.
REMEMBER THAT
THE DIAGNOSTIC AND ANY TREATMENT OF HYPERTENSION MAY BE CON-
DUCTED ONLY BY A CERTIFIED DOCTOR ON THE BASIS OF BLOOD PRESSURE
VALUES OBTAINED BY THIS DOCTOR. TAKING OF DRUGS AND THEIR DOSES
SHOULD BE PRESCRIBED ONLY BYYOUR ATTENDING DOCTOR.
Fig. 1
4 . KEEP QUIET DURING A MEASUREMENT TO OBTAIN THE ACCURATE VALUES
OF YOUR BLOOD PRESSURE WITH THE ELECTRONIC DEVICE. Measure your
blood pressure in the calm and comfortable conditions at the indoor tem-
perature. No eating an hour before measurement; no smoking, taking tonic
agents, alcohol 1.5-2 hours before measurement
.
5. The accuracy of blood pressure measurement depends on whether the
cuffmatches the size of your arm. THE CUFF SHOULD NOT BE TOO SMALL OR
TOO LARGE.
6 . Wait 3 minutes between measure-
ments for the blood to restore its cir-
culation. However, the persons with
prominent atherosclerosis due to
considerable loss of vascular elasticity
may need to increase the wait time be-
tween measurements (10-15 minutes).
This also refers to the patients suffering
for long from diabetes. For more accu-
rate determination of blood pressure it
is recommended to make a series of 3
consecutive measurements and to use
the average value

ADAPTATION FOR LEFTHANDED
If you prefer to pump air with your left hand, perform the following steps to
adapt the device:
1. Disconnect the cufftubing
from the hose nozzle of the
air valve.
2. Loosen the locking ring
by turning as indicated in
Figure 3.
3. Turn the air valve super-
charged 180°, as shown in
Figure 3.
4.
Fix the present position
of the valve relative to the
gauge by turning the locking
ring. The device takes the
form shown in Figure 4.
5. Attach the cufftube to the hose nozzle of the air valve.
IF YOU PUMP AIR WITH YOUR RIGHT HAND, NO NEED TO PERFORM THE
ACTIONS LISTED IN THIS SECTION.

CUFF PREPARATION
1. Insert the cuffend for about 5 cm into a metal ring as
shown in the fig. 5 (if cuffiswithring).
Fig. 5
2. Apply the cuffto your left upper arm so that the air tube
is directed to your palm (fig. 6). If the measurement on your
left arm is difficult, you may use your right arm. In this case
remember that the readings may differ by 5-10 mmHg and
even more.
Fig. 6
3 . Wrap the cuffaround your upper arm so that the
bottom of the cuffis approximately 2-3 cm above
your elbow. The sign “ARTERY” should be over the arm
artery as shown in the fig. 7.
Fig. 7
4. Fix the cuffso thatit fits tightly to the arm, but see that
it is not overtight. Too tight or too free placement of the
cuffmay give inaccurate readings.
Fig. 8
5. On the fixed cuffthe sign «INDEX» should point to the area
«NORMAL» (fig9).Itmeansthatthecuffischosencorrectlyandfits
the size of your upper arm. If the sign points to the area marked «
» or to the left, the cuffis too small and the readings will be
higher. If the sign points to the area marked « » or to the right,
the cuffistoolargeandthereadingswillbelower.
Fig. 9
6. If the arm has a conic form, the cuffshould be put on
with a spiral movement as shown in the fig. 10.
Fig. 10
7. If the rolled-up sleeve squeezes the arm interfering
with free blood flow the Device may give inaccurate fig-
ures not corresponding to your actual blood pressure
(fig. 11).

8. Place stethoscope head so that it was located in depres-
sion, somewhat higher than elbow bend (Fig. 12). If You
use the device with built-in stethoscope, to reach better
auscultation of pulse on full hand, the cuffmay be turned
round the hand approximately by quarter of circle (60-90˚)
in such way that stethoscope head would be positioned on
inner side of hand (more close to the body).
Fig. 12
9. Pressure shall be measured in sitting or lying position of human. IN SITTING
POSITION WATCH THAT PART OF HAND WITH CUFF WOULD BE LOCATED AT THE
LEVEL OF HEART, AND HAND WOULD BE FREELY LOCATED ON THE TABLE AND
WOULD NOT MOVE
.
MEASUREMENT PROCEDURE
1. Insert metal tubes of stethoscope into ears. Close air valve on air pump,
having turned it clockwise. Squeezing air pump, pump up the cuff, listen-
ing to pulse by stethoscope. After You stopped to listen to pulse, pump
up the cuffby 30 mm Hg more
.
2. Slowly opening air valve, turning it counterclockwise, bleed down pressure
in the cuff. Watch that pressure in the cuffwould fall down at speed 2-4 mm
Hg per second. This is necessary to get accurate result.
3. As soon as You hear weak pulse beats, memorize manometer reading. This
is Your systolic (upper) arterial pressure
.
4. Pressure in the cuffis continuing falling down at the same speed (2-4 mm Hg
per second). You are continuing to listen to pulse. Sounds which You hear will
change. Unlike the first beats, they will become softer, resembling rustling.
At the moment when You practically stop seize pulse, memorize manometer
reading. This is Your diastolic (lower) arterial pressure.
CARE, STORAGE, REPAIR AND DISPOSAL
