ABOUT BLOOD PRESSURE

What is Blood Pressure?
Blood pressure is the pressure exerted on the artery walls while blood flows through the arteries. The pressure measured when the heart contracts and sends blood out of the heart is systolic (highest) blood pressure. The pressure measured when the heart dilates with blood flowing back into the heart is called diastolic (lowest) blood pressure.

Why Measure Your Blood Pressure?
Among today’s various health problems, those associated with high blood pressure are very common. High blood pressure dangerously correlates with cardiovascular diseases. Therefore, blood pressure monitoring is important for identifying those at risk.

BLOOD PRESSURE STANDARD

The table on page 6 contains defined levels for hypertension that are publicly available from the National Heart Lung and Blood Institute at the U.S. National Institutes of Health (NIH) (http://www.nhlbi.nih.gov/health/dci/Diseases/Hbp/HBP_WhatIs.html). Users can compare their own blood pressure readings against these defined levels to determine if they may be potentially at increased risk.

This table is applicable to most adults aged 18 and older.

Blood pressure tends to go up and down, even in people who normally don’t have high readings. If your numbers stay above the “normal” range most of the time, you may be at increased risk and should consult your physician.

Although one can easily find where their own blood pressure readings fall on this table, this monitor comes equipped with a Risk Category Index that automatically compares each reading to the defined levels and provides a helpful cue if your reading falls into one of the stages that could potentially indicate increased risk. See page 19 for more information on this feature.

Please note that cues provided by this monitor are only intended to assist you in using this table. The table and cues are only provided for convenience to help you understand your non-invasive blood pressure reading as it relates to the NIH information. They are not a substitute for a medical examination by your physician. It is important for you to consult with your physician regularly. Your physician will tell you your normal blood pressure range as well as the point at which you may actually be considered to be at risk.

HOW THIS BLOOD PRESSURE MONITOR WORKS

This monitor uses innovative technology to detect your blood pressure. This technology enables the monitor to automatically inflate and deflate at the appropriate level for each individual. With one touch of a button, the cuff will automatically inflate to block the blood flow through your artery. Next, the deflation process starts.

Please note that any muscle movement during inflation or deflation will cause measurement errors. When the measurement is complete, the monitor will display your systolic pressure, diastolic pressure, and pulse readings.

The monitor automatically finds where your measurement results fall on the NIH’s National Heart Lung and Blood Institute’s table and provides a cue if your reading falls into one of the stages that could potentially indicate increased risk. See page 19 for more information on this feature.

The appearance of the icon indicates that a pulse irregularity consistent with an irregular heartbeat was detected during measurement. Refer to page 20 for more information on the Irregular Heartbeat Detector.

NAME/FUNCTION OF EACH PART

DISPLAY EXPLANATIONS

Display Symbols:

If and any of the following letters and numbers appear in the area that systolic pressure should be displayed, an error has occurred with your reading. See the Troubleshooting section of this manual for more information.

INSTALLING BATTERIES

1. The battery cover is located along the side of the monitor. Remove the battery cover by pressing down and pulling away from the monitor.

2. Install batteries according to the polarity indications inside the compartment (as shown in figure 2). Battery Type: 2 Alkaline LR03 “AAA” size

3. Insert the other battery, according to the polarity indications inside the compartment (as shown in figure 3).

4. Replace the cover by inserting it back into place.

Replace the batteries if:

• The weak battery symbol appears on the display.
• Nothing appears on the display when the power is switched on.

As the supplied batteries are for test only, they may be discharged earlier than batteries you buy in stores. Replace all batteries at one time (as a simultaneous set). Use only 1.5V “AAA” alkaline batteries. Remove batteries when the unit is not in use for extended periods of time. The date and time will need to be reset if batteries are removed or replaced. Clean contacts on the battery and in the battery compartment with a soft dry cloth each time you install batteries.

Note:
Batteries are hazardous waste. Do not dispose of them together with the household garbage.

DATE and TIME SET PROCEDURE

1. To adjust the date and time, press the DATE/TIME SET button located on the top of the monitor.
2. The display will show a blinking number showing the HOUR. Change the HOUR by pressing the button. Each press will increase the number by one in a cycling manner. Press the DATE/TIME SET button again to confirm the entry, and the screen will show a blinking number representing the MINUTE.
3. Change the MINUTE, MONTH, DAY, and YEAR as described in Step 2 above, using the button to change the numbers and the DATE/TIME SET button to confirm the entries.

APPLYING THE CUFF

1. Remove all watches, wrist jewelry, etc. prior to attaching the wrist monitor. Clothing sleeves should be rolled up and the cuff should be wrapped around bare skin for correct measurements.

2. Apply the cuff to the left wrist with the palm facing up as shown in Fig. A.

3. Make sure the edge of the cuff is about 1/4”~1/2” (1 cm) from the palm as shown in Fig. B.

4. In order to ensure accurate measurements, fasten the hook and loop strap securely around your wrist so there is no extra space between the cuff and the wrist. If the cuff is not wrapped tight enough, the measurement values will not be accurate.

5. If your physician has diagnosed you with poor circulation in your left arm, place the cuff around your right wrist as shown in Fig. C.

Note:
• This device should not be used when your wrist is wounded or injured.
• If it is not possible to use the cuff on your left wrist, it can also be used on your right wrist. However, all measurements should be made using the same wrist.

CORRECT MEASUREMENT POSTURE

1. Place your elbow on a table so that the cuff is at the same level as your heart as shown in Fig. A. Relax your entire body, especially between your elbow and fingers.

Note: Your heart is located slightly below your armpit.

2. If the cuff is not at the same level as your heart or if you cannot keep your arm completely still throughout the reading, use a soft object such as a folded towel to support your wrist as shown in Fig. B.

3. Turn your palm upwards.

4. Sit upright in a chair, and take 5-6 deep breaths.

Avoid leaning back while the measurement is being taken as shown in Fig. C.

MEASUREMENT PROCEDURE

Important Notes:

Position the monitor at the same level as your heart during measurement to ensure accurate readings.
Blood pressure changes with every heartbeat and is in constant fluctuation throughout the day.
Blood pressure measurement can be affected by the position of the user, his or her physiologic condition, and other factors. For greatest accuracy, wait 1 hour after exercising, bathing, eating, drinking beverages with alcohol or caffeine, or smoking to measure blood pressure.
Before a measurement, it is suggested that you sit quietly for 15 minutes as measurements taken during a relaxed state will have greater accuracy. You should not be physically tired or exhausted while taking measurements.
During the measurement, do not talk or move your arm or hand muscles.
See page 22 for additional notes regarding your blood pressure measurement.

If you are using this blood pressure monitor for the first time, please remove the protective film from the screen.

1. With the cuff wrapped around your wrist, press the START/STOP button. Do not inflate the cuff unless it is wrapped around your wrist. All digits will light up, checking the display functions. The checking procedure will be completed after about 3 seconds.

2. After all symbols disappear, the display will show “00”. The monitor is “Ready to Measure” and will automatically inflate the cuff to begin measurement. The cuff will then begin deflating as measurement continues.

Note:
The monitor will re-inflate automatically if the system detects that your body requires more pressure for measurement.

3. When the measurement is completed, the cuff will deflate entirely and systolic pressure, diastolic pressure, and pulse will be shown simultaneously on the LCD screen. The measurement is then automatically stored in memory.

Note:

This monitor automatically turns off approximately 1 minute after the last operation. You may also press the START/STOP button to turn the unit off.
To interrupt the measurement, you may press the START/STOP button (recommended), the MEMORY button, or DATE/TIME SET () buttons. The cuff will deflate immediately after a button is pressed.

RISK CATEGORY INDEX

This monitor comes equipped with a Risk Category Index that automatically compares each reading to defined levels established by the U.S. National Institutes of Health’s (NIH) National Heart Lung and Blood Institute as described earlier in this manual, and provides a helpful cue if your reading falls into one of the stages that could potentially indicate increased risk. No cue is given if the reading falls in the normal range as defined by NIH. Please note that cues provided by this monitor are only intended to assist you in using this table. The table and cues are only provided for convenience to help you understand your non-invasive blood pressure reading as it relates to the NIH information. They are not a substitute for a medical examination by your physician. It is important for you to consult with your physician regularly. Your physician will tell you your normal blood pressure range as well as the point at which you may actually be considered to be at risk.

IRREGULAR HEARTBEAT DETECTOR (IHB)

The appearance of the icon indicates that a pulse irregularity consistent with an irregular heartbeat was detected during measurement. Usually this is not a cause for concern. However, if the symbol appears often, we recommend you seek medical advice. Please note that the device does not replace a cardiac examination, but serves to detect pulse irregularities at an early stage.

Movement, shaking, or talking during the measurement can result in pulse irregularities that may cause the appearance of this icon. Therefore, it is of great importance to not move or talk during measurement.

To determine the presence of an irregular heartbeat, the average of the heartbeat intervals is calculated with the first 3 normal effective heartbeat values. It is important to note that the average is not a strict mathematical averaging of all recorded intervals. At least 3 beats with a 25% or greater difference from the average heartbeat interval will generate the icon on the screen.

IMPORTANT INFORMATION:
This blood pressure monitor is not designed for use by people with arrhythmias nor for diagnosing or treating an arrhythmia problem. As a safeguard, we recommend that if you have arrhythmias such as atrial or ventricular premature beats and atrial fibrillation or any other special conditions you should check with your physician before using your blood pressure monitor.

RECALLING VALUES FROM MEMORY

1. Press the MEMORY button to access the memory.

2. Every new press of the MEMORY button will recall a previous reading. The latest reading will be recalled first.

CLEARING VALUES FROM MEMORY

Press and hold the and buttons at the same time while in memory recall mode and the data will be erased automatically.

IMPORTANT NOTES REGARDING YOUR BLOOD PRESSURE MEASUREMENT

Take your reading in a comfortable environment as measurements can be affected by hot or cold temperatures. Take your blood pressure at normal body temperature.
Do not move or talk during measurement as this can elevate readings.
Do not move or cross legs during measurement. Keep feet flat on the floor.
