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.

Why do my readings vary?
Blood pressure is a body parameter that is subject to normal variations throughout the day. A single reading that is different from your and your doctor's readings are not necessarily inaccurate. The average of several readings, taken under similar conditions, using the same arm, is preferred for accurate blood pressure readings.

Why are my readings different than those taken at my doctor's office?
Many experience a phenomenon called "White Coat Hypertension" when measured by a doctor. White Coat Hypertension refers to blood pressure that rises above its usual level when measured in a clinical setting, such as a doctor's office.

BLOOD PRESSURE STANDARD

The table below contains defined levels of hypertension from the World Health Organization (WHO). The WHO has established globally accepted standards from the assessment for high blood pressure readings. Users can compare their own blood pressure readings against these defined levels to determine if they may potentially be at increased risk. This table is applicable to most adults age 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 an increased risk.

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 WHO 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.

NOTE: This blood pressure monitor uses defined levels for hypertension from World Health Organization (WHO). This table provides the American Heart Association blood pressure guidelines (AHA 2017) for your reference. You can compare your readings to this chart to know where your measurement falls according to the AHA 2017 defined levels for hypertension.	Blood Pressure Category	Sistolic mmHg (upper number)		Diastolic mmHg (lower number)
	Normal	Less than 120	and	Less than 80
	Elevated	120 – 129	and	Less than 80
	High Blood Pressure (Hypertension) Stage 1	130 – 139	or	80 – 89
	High Blood Pressure (Hypertension) Stage 2	140 or higher	or	90 or higher
	Hypertension Crisis	Higher than 180	and/or	Higher than 120

Replace the batteries if:

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

NOTE:

• Date and time must be reset if batteries are removed or replaced.
• Replace all batteries at one time (as simultaneous set). Use only 1.5V AAA alkaline batteries.
• When the batteries are removed, the measurement values stored in memory are retained.
• Clean contacts on battery and in battery compartment with a soft, dry cloth each time you install batteries.
• Batteries are hazardous waste. Do not dispose of them together with household garbage.

DATE AND TIME SET

It is necessary to set the date and time for the unit every time batteries are initially installed or replaced.

	Memory Average: Displays average of last 3 readings.
	Pulse Symbol: Shows the heart rate per minute.
	WHO Risk Category Indicator: See Blood Pressure Standard section.
	Low Battery Symbol: Appears when batteries should be replaced.
	Irregular Heartbeat Detector: See below for more information.

IRREGULAR HEARTBEAT DETECTOR

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 25% or greater difference from the average heartbeat interval will generate the icon on the screen.

USING THE ARM CUFF

1. If the cuff is not assembled, pass the end of the cuff farthest away from the tubing through the metal D-ring in order to form a loop. The smooth side without the felt material should be on the inside of the loop.
   
2. Plug the cuff tube into the left side of the unit.
   
3. Place the upper arm cuff approx. ¾" – 1 ¼" above elbow. Pull the end of the cuff so that it tightens evenly around your arm. Press the hook and loop material together to secure. There should be room for 2 fingers to be placed between the cuff and arm. Center tube over the middle of the arm.
   

Please note:
To use the right arm, you must position the artery symbol " " over the main artery. Locate the main artery by pressing with 2 fingers approximately 1" (2cm) above the bend of your elbow on the inside of your right arm. Identify where the pulse can be felt the strongest. This is your main artery.

MEASUREMENT PROCEDURE

DURING MEASUREMENT

• Do not talk or move your arm or hand muscles.
• Do not cross your legs. Sit with feet flat on the floor.
• Do not touch cuff or monitor during measurement.

1. Press POWER button to turn the monitor ON. The display will perform a selftest, then the values from the last reading will appear on the display.
   
2. The blood pressure monitor will start to measure. The cuff will automatically begin to inflate, with the display showing the increasing pressure in the cuff. As the pressure increases, an arrow pointing up will appear on the display.
   
3. When the inflation has reached optimum level, the display will begin to show decreasing pressure and an arrow pointing down will appear.
4. To detect the heartbeat, the heart symbol will appear and continuously flash on the LCD display.
5. Your blood pressure measurement and pulse will display simultaneously on the screen.
6. Press the M1 button to record the measurement into the MEMORY Recall Button M1.
7. Press the M2 button to record the measurement into the MEMORY Recall Button M2.

NOTE:

• This monitor automatically turns off approximately 2 minutes after last operation. You may also press the POWER button to turn the unit off and record the measurement result in to the MEMORY Recall M1.
• To interrupt the measurement, you may press the POWER button. The cuff will deflate immediately after a button is pressed.

RECALLING VALUES FROM MEMORY

This monitor can be used by 2 individuals. Each user can store up to 90 measurements.

1. Press and release either the M1 or M2 button. The unit will first display the average of the last 3 stored measurements.
   
   
2. Every new press of the M1 or M2 button will recall a previous reading. The latest reading will be recalled first.
   
   
3. To stop recalling readings from memory, press the POWER button.
