IDENTICATION OF PARTS

GENERAL REMARKS

General remarks on blood pressure and blood pressure measurement

To deflate the cuff quickly, press the "Exhaust button".
The attached cuff (model SCN-004) is suitable for arm circumferences of 22-32 cm.
When attaching the cuff, adjust the position of the cuff so that the blue marker is located in the center of your arm and the hem of the cuff is 1-2 cm above your elbow.
The monitor is not intended to be a diagnostic device, because it is intended for home use.
Self measurement is not therapy! In no event should you change the dosage of your medication prescribed by your physician.
As preparation for measuring your blood pressure, you should urinate and then remain relatively still for 10 to 15 minutes prior to measurement.
Exercising, eating, drinking, smoking, etc., prior to measurement may affect the results.
Your blood pressure varies constantly throughout the day. Measurements should be taken regularly at the same time each day.
DO NOT place too much emphasis on the results of one measurement. Keep a continuing record of your blood pressure variations. A complete picture can only be obtained from a large number of readings.
Emotional stress tends to cause your blood pressure to rise.

To obtain correct blood pressure measurements

Take five or six deep breaths and then relax before measuring your blood pressure. If you are tense when taking the measurement, you will not get a valid reading.
Your blood pressure will be elevated if you are anxious or irritated, suffering from lack of sleep or constipation, or have just taken some exercise or eaten a meal.
Wrap the cuff around your arm and tighten it so that one finger can be inserted between the cuff and arm.
DO NOT measure your blood pressure after bathing or drinking.
If you feel the need to urinate, do so before measuring your blood pressure.
Measure your blood pressure where the room temperature is around 20°C. DO NOT measure your blood pressure when it is too cold (below 10°C) or too hot (above 40°C) in the room.
DO NOT try to measure your blood pressure immediately after drinking coffee or tea or after smoking.
Measure your blood pressure when you are relaxed and still. Keep the center of the cuff at the level of your heart and DO NOT move your arm or talk.
DO NOT measure blood pressure when the cuff has been on your arm for a few minutes or more. During this time, your arm will have built up a higher blood pressure and you will not get valid reading.
The figure below shows the blood pressure classifications under the WHO standards.

Definitions and Classifications of Blood Pressure Levels

Remarks:
The graph is not exact, but may be used as a guide in understanding non-invasive blood pressure measurements.
The device is only intended for use by adults.

Intended Use

This device is noninvasive blood pressure monitor by oscillometric method. This device can measure the systolic blood pressure (SYS), the diastolic blood pressure (DIA) and the pulse rate automatically.
This device is intended to be used for checking personal health condition at home under the direction of a physician and is not intended to be a diagnostic device.
This device is not intended for use with neonates or infant, and not intended for automatic cycling measurement.

Measure your blood pressure at the same time each day

* Your blood pressure changes all the time. This means that data gathered over a long period has far more significance than data from just one measurement. For this reason, you must measure your blood pressure on a daily basis. Ideally, you should measure your blood pressure at the same time each day, wherever possible.

PRECAUTIONS FOR USE AND MAINTENANCE

Precautions for use

If you suffer from heart disease, high blood pressure or other circulatory disease, consult your physician before using the monitor.
If the cuff pressure feels abnormal or you experience any other irregularity while using the cuff, reduce the pressure immediately by pressing the "Exhaust button", detach the cuff or unplug the air hose connector from the monitor and then consult the sales outlet where you purchased the monitor.
If you think the measurement is abnormal or if measurement makes you feel unwell, discontinue use and consult your physician.
Blood pressure measurement may not be possible for anyone with a weak pulse or arrhythmia.
Repeated blood pressure measurement may cause problems such as congestion or swelling in some people.
Frequently repeated blood pressure measurements will not give accurate results. Allow an interval of about 1 minute between measurements.
If you suffer from a severe problem with blood circulation in your arms, consult your physician before using the monitor. Failure to do so could be hazardous to your health.
Measurement may not be possible for anyone with insufficient blood flow to the area where measurements will be taken or who suffers from a frequent irregular heartbeat. Consult your physician for advice on whether to use the monitor.
DO NOT wrap the cuff around an injured arm.
DO NOT wrap the cuff around an arm in which a drip (intravenous infusion) is inserted, or which is being used for blood transfusion as part of medical treatment. Doing so could result in an injury or a serious accident.
DO NOT use the monitor in the vicinity of flammable gases such as those used for anaesthesia. Doing so could ignite the gases and cause an explosion.
DO NOT use the monitor in enriched oxygen environments such as a hospital's hyperbaric chamber or oxygen tent. Doing so could ignite the oxygen and cause a fire.
DO NOT use mobile phones near the monitor as this could result in a malfunction.
If you use a cardiac pacemaker, consult your physician before using the monitor.
Be sure to use this unit only for measuring blood pressure. DO NOT use it for any other purpose.
Be sure to use only our authorized parts and accessories. Parts and accessories not approved for use with the device may damage the unit.
DO NOT use this unit on infants.
Blood pressure measurement may not be possible for anyone with common arrhythmias such as atrial or ventricular premature beats or atrial fibrillation.

Maintenance Precautions

DO NOT store the blood pressure monitor in locations exposed to direct sunlight, high temperatures (over 60°C), low temperatures (below -20°C), high relative humidity (over 95%) or excessive amounts of dust.
Make sure to store the blood pressure monitor, where children, pets and or pests are not there.
DO NOT drop the blood pressure monitor or subject it to other shocks or vibration.
Remove the batteries if the monitor will be left unused for a long period.
DO NOT attempt to disassemble the monitor.
DO NOT bend the cuff or the air hose excessively.

MEASURING YOUR BLOOD PRESSURE

ATTACHING THE CUFF

Unroll the cuff and thread the end through the metal hoop so that the side with the hook-and-loop fastener is on the outside.
Put the cuff around your arm so that the blue marker comes to the palm side.
Adjust the position of the cuff so that the blue marker is located in the center of your arm and the hem of the cuff is 1-2 cm above your elbow.

* The cuff should be put on the bare arm or over a light-weight underwear.
* If you wear a heavy-weight top, please remove it.
Pull the end of the cuff outwards so that the cuff is snug around your arm and then secure the end to the hook-and-loop fastener.
Place your arm on a table or the like, so that the center of the cuff comes to the height of your heart.
Relax your arm and lightly open your hand, with the palm upward.

Turn Power On

Push the cuff tube and Pumping bulb tube over the air connectors.

Press the "Power" switch for Power on.

All display mark appear for approx. 1 second and buzzer beeps.

After all display marks are disappeared, the last measured systolic and diastolic blood pressure values are displayed.
(Value of Pulse is not memorized nor displayed).

Memory function works on for approximately 2 second or duringdepressed the "Power" switch.

After memorized blood pressure value is disappeared, deflation mark " " appears.

If there is some air remaining in the cuff, release air with the exhaust button until the "0" appears. The buzzer beeps three times. The unit is now ready to take new measurement.

Pressurize the cuff

Pressurize the cuff by pumping bulb until you have a reading of approximately 30 to 40 mmHg higher than your regular systolic blood pressure.
Note: At pressure of 140,170, 200, 240 mmHg, the buzzer beeps two times.

When pressurization is completed, the automatic the automatic air release system will gradually reduce cuff pressure, and Measuring Mark " " will appear on the display indication that measurement is in progress.

When a pulse is detected, the pressure value moves to the right side of the display. At this time Measuring Mark " " flashes with a short beep at the same time as pulse rate.

When the diastolic pressure valve is detected, the measurement is completed and buzzer beep. Systolic pressure is displayed on the left and diastolic pressure on the right side of the display. After completion of measurement, the mark " " appears.

Approximately 2 seconds later, blood pressure values and pulse appear alternatively on the display.

Press the exhaust button

Press the exhaust button valve to completely release the air in the cuff.

Power off

Press the "POWER" switch to turn off.
About 3 minutes after the last measurement was obtained, the power will be turned off, automatically.

Q & A

Why is the blood pressure measured at home different from that measured by the physician or at a hospital?

Your blood pressure may vary due to exercise, the ambient temperature or your mental state. When you have a physician or nurse measure your blood pressure, the pressure value is likely to be 10 to 20 mmHg higher than usual due to anxiety and/or stress. Knowing what affects your blood pressure helps you to better monitor your health.

Why does the blood pressure obtained vary with measurement

Our blood pressure is adjusted by automatic nerve function. Blood pressure differs with every heart beat. We are likely to think that our blood pressure is constant, but it varies if you take measurements in repetition. Blood pressure is susceptible to the time of day, such as morning and afternoon, season and atmospheric temperature. In addition, blood pressure is easily affected by mental stress or emotional ups and downs. It tends to increase when you feel tension or decrease when you are relaxed.

warning Always consult your physician for an interpretation of your blood pressure readings and to determine the proper treatment.
