The digital automatic blood pressure monitor is suitable for home healthcare

environment and is a non-invasive blood pressure measurement system intended to

measure the diastolic and systolic blood pressures and pulse rate of an adult individual

by using a non-invasive technique in which an inﬂ atable cuff is wrapped around the

upper arm. The cuff circumference is limited to 22 cm-42 cm.

5. CONTRAINDICATION

It is inappropriate for people with skin wounds on upper arms.

6. PRECAUTIONS

1. Before use, please read this instruction manual carefully.

2. In case of questions on the use of blood pressure monitor and resulting blood

pressure values, please contact a doctor.

3. Keep MED-55 out of the reach of children.

4. Do not use MED-55 near anesthetic, ﬂ ammable or oxygen mixture, or with nitrous

oxide.

5. Do not forget: self-measurement means control, not diagnosis or treatment.

Unusual values must always be discussed with a doctor. Under no circumstances a

treatment should be altered or changed without a doctor’s prescription.

6. The pulse display is not suitable for checking the frequency of heart pacemakers.

7. In cases of cardiac irregularity (I.H.B.), measurements made with this device should

only be evaluated after consultation with a doctor.

8. Changes to the unit by the user are not admitted.

9. We recommend consulting a doctor before using the blood pressure monitor on

patients with pre-eclampsia or during pregnancy.

10. The device does not require any calibration.

11. Tubing kinking can cause continuous cuff pressure and may result in blood ﬂ ow

interference and patient injury.

12. Too frequent measurements can cause injury to the patient due to blood ﬂ ow

interference.

13. Please note that, when inﬂ ating, the functions of the limb in question may be

impaired.

14. During the blood pressure measurement, the blood circulation must not be

stopped for an unnecessarily long time.

15. If the device malfunctions remove the cuff from the arm.

16. The user must check that the equipment functions safely and see that all its parts

are in proper conditions before use.

17. Please always relax a minimum moment of 1-1,5 minutes between measurements

to allow the blood circulation in your arm to recover. Prolonged over-inﬂ ation

(cuff pressure exceed 300 mmHg or maintained above 15 mmHg for longer than 3

minutes) of the bladder may cause ecchymoma of your arm.

18. Consult your physician if you have any doubt about below cases:

1) The application of the cuff over a wound or inﬂ ammation diseases;

2) The application of the cuff on any limb where intravascular access or therapy, or

an arterio-venous (A-V) shunt, is present;

3) The application of the cuff on the arm on the side of a mastectomy;

4) Simultaneously used with other monitoring medical equipments on the same limb.

phones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast

cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due

to ﬁ xed RF transmitters, an electromagnetic site survey should be considered. If the measured

ﬁ eld strength in the location in which the MED-55 is used exceeds the applicable RF compliance

level above, the MED-55 should be observed to verify normal operation. If abnormal perfor-

mance is observed, additional measures may be necessary, such as re-orienting or relocating

the MED-55.

b. Over the frequency range 150 kHz to 80 MHz, ﬁ eld strengths should be less than 3 V/m.

Press and hold “Start” button for more than 3 seconds. The Time/Date information

disappear on the display. Release the “Start” button and the arm cuff starts to

inﬂ ate automatically. After measurement is taken, the cuff deﬂ ates and the values

are shown on the display illuminated with WHO color. No values are stored in the

memories.

Both single measurement mode and “3check” mode are availabe for measuring in

Guest mode.

7.9. Taking your blood pressure reading

a. After the cuff has been appropriately positioned, press “Start” button to start

measure. “0” appears in “DIA” ﬁ eld: the monitor is ready for the measurement.

See Picture 7-1.

b. Cuff inﬂ ation starts and display shows increasing pressure values in “DIA” ﬁ eld. The

“Cuff position control” symbol is displayed throughout the entire measurement. See

Picture 7-2. If the cuff is applied too tightly or too loosely, then the Error symbol E3

is displayed and the “Cuff position control” symbol is blinking.

c. As the heartbeat is detected, the “Heart beat” symbol blinks and a beeping sound

is generated at the same rhythm of the heartbeat. When the measurement is

completed, cuff is deﬂ ated.

d. When the device is set to 3check mode, generally 3 separate measurements will

take place in succession and calculates your detected blood pressure value.

There will be 15 seconds resting time in-between each measurement.

A count down indicates the remaining time and a beep will sound 5 seconds

before the 2nd and 3rd reading begin. In the case where a single piece of data

from each cycle differs too much from each other, a fourth measurement is

performed before the result will be displayed. After all the measurements are

completed the display shows the result.

e. In single measurement mode after the ﬁ rst measurement is completed and cuff is

deﬂ ated the display shows the systolic/diastolic pressure and pulse.

f. The backlight of the display is lighted according to WHO color scale and WHO

segments are displayed according to the measured values.

g. The appearance of the Pulse Arrhythmia Detection symbol signiﬁ es that an

irregular heartbeat was detected. See Picture 7-3.

h. The measurement value will be automatically stored. If the measurement was

taken in “3check” mode the symbol “3check” will appear on the display with the

measurement result.

i. After measurement, the monitor will turn off automatically after 1 minute of no

operation. Alternatively, you can press the “Start” button to turn off the monitor

manually.

During measurement, you can press the “Start” button to turn off the monitor

manually.

NOTE:Please consult a health care professional for interpretation of pressure

measurements.

7-1 Picture 7-2 Picture 7-3

7.10. Pulse Arrhythmia Detection

The appearance of the symbol

signiﬁ es that a certain pulse irregularity was

detected during the measurement. The result can vary from your normal blood

pressure. It is better to repeat the measurement. As a rule this is not a cause for

concern; however, if the symbol

appears more frequently (e.g. several times

per week on measurements performed daily) or if it suddenly appears more often

than usual, we recommend you inform your doctor.

7.11. Trafﬁ c Light Indication

The colored bars on the left-hand edge of the display show you the range within

which the indicated blood pressure values lies. Depending on the height of the bar,

the readout value is either within the normal (green), borderline (yellow and orange)

or danger (red) range. If the values of systole and diastole fall into two different

categories (e.g. systole in the High normal category and diastole in the Normal

category), the graphical classiﬁ cation on the device always shows the higher category

(e.g. High).

The classiﬁ cation corresponds to the 6 ranges in the Table as deﬁ ned by the ESH and

described on the table of the point 2. The recommendations of the European Society of

Hypertension (ESH) allow to diagnose and treat the hypertension more effectively and

do not contradict World Health Organization recommendations.

Please note that these standard values serve only as a general guideline, as the

individual blood pressure varies in different people and different age groups etc., it is

important to consult your doctor regularly for advice.

Additionally, the colours on the display differ according to the readings. If, for example,

the readings are in the range of 1, 2,3 the display light is green, in the range of 4,5 the

light is yellow, and in the range of 6 the display light is red.

7.6. Carrying out a measurement

Before the measurement:

Avoid eating, smoking as well as all forms of exertion directly before the

measurement. All these factors inﬂ uence the measurement result. Try and ﬁ nd

time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes

before the measurement.

Measure always on the same arm.

Attempt to carry out the measurements regularly at the same time of day, since

the blood pressure changes during the course of the day.

Sitting Comfortably Measurement:

a. Be seated with your feet ﬂ at on the ﬂ oor, and don’t cross your legs.

b. Place palm upside in front of you on a ﬂ at surface such as a desk or table. Make

sure to be sit in a comfortably position with your arms extended and back leaning

on the seatback.

c. The middle of the cuff should be at the level of the heart. To avoid errors in the

measurement, it is important to remain immobile during the measurement and in

silence.

Common sources of error:

Movement during measurement

The arm artery lies considerably lower (higher) than the heart

The cuff does not ﬁ t you in size

Loose cuff or a sideways protruding air-pocket

Warning: Only use original cuffs!

With repeated measurements, blood accumulates in the respective arm, which can

lead to false results. Correctly executed blood pressure measurements should

therefore ﬁ rst be repeated after a 1 minute pause.
