Indications for use:
The device is a non-invasive monitor intended for use in measuring blood pressure and pulse rate in adult population.
The device also estimates the arterial complicance (elasticity of arterial wall) during measurement and gives an indication with readings.
The device is not intended to be a diagnostic device.
Please read the entire manual carefully before using this Arterial hardness & Blood Pressure Monitor.
Only a physician is qualified to interpret changes in your blood pressure. This device is not intended to replace regular medical examinations. It is recommended that your physician review your procedure for using this monitor. Never make adjustments to your medication unless it is the advice of a physician.
This device is intended for adult use. Do not allow children to play with this device.
Do not wrap the cuff around any parts of the body other than an adult’s arm.
Substitution of a component different from that supplied might result in measurement error.
The H-Value technology requires 5 to 15 minutes rest before taking every measurement.
What is Arterial Hardness Indication and How to Interpret the Results Correctly?
Regular medical check-ups play an important role in your personal health management. We hope this Arterial Hardness Indication (H-Value) will motivate you to lead a healthier lifestyle, and it could also act as a reminder for you not to forget your regular check up, or even seek an earlier appointment (e.g. If the average of H-Value constantly indicated 7-8 bars).
Besides measuring blood pressure and pulse, this device also estimates the compliance (elasticity) of your brachial artery during blood pressure measurement. This H-Value indication is a result of the measurement on brachial artery, which may or may not reflect the arterial hardness condition of the entire body.
1) Arterial Hardness – Arterial hardness describes a biological change in the physical property of the arteries in particular the property of elasticity. If hardening of the arteries is not controlled, it can lead to further complications in the blood vessels of the heart and the brain. The harder your arteries are, the less elastic they are. This unique technology has been given three different names as AHI (Arterial Hardness Indication) or ASI (Arterial Stiffness Indication) or H-Value (degree of arterial hardness).
2) Arteriosclerosis – This means a person’s arteries have hardened to such a serious degree that a physician would diagnose it as a disease. Such disease may induce Stroke or Heart Attack etc. The degree of Arteriosclerosis is difficult to diagnose since it progresses slowly and silently. Caution: This device does not estimate Arteriosclerosis.
Correct Steps and Procedure
1) A single measurement of BP and H-Value reflects only the moment of measurement, similar to BP, the H-Value fluctuates due to emotion, stress, nervousness, temperature and some medications.
Daily fluctuations (2-5 bars) of H-Value is considerably normal.
2) The best use of this unique technology is to help you to monitor the current status and the future trend of your arterial hardness. You must build a base of the AVERAGE of your H-Value by taking around 30 measurements. When turning the power off, the LCD display will show the AVERAGE value from all the previous measurements. (30 maximum)
It helps to remind and motivate you to decrease (or least to maintain) the AVERAGE number of bars, either by improving your lifestyle or consulting your doctor.
Classification: Blood Pressure
The classifications provided in this manual are recommendation for reference only and are revised by their respective publishers from time to time. They are for reference only, and must not be sued for self-diagnosis by patients. Any treatment or medication adjustment must be given by doctors only.
The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure has published the following chart to classify blood pressure:
|Normal*||Less than 120||and||Less than 80|
|Stage 2||160 or higher||or||100 or higher|
*Unusually low reading should be evaluated for clinical significance.
Hints for Accurate Measurement.
1) Rest 5-15 minutes before taking a measurement, and remain still during testing.
2) Remove any heavy clothing on the upper arm (shirts are acceptable). Constriction of the upper arm caused by rolling up a shirt sleeve may cause an inaccurate reading.
3) Refrain from eating, smoking, and drinking (especially alcoholic beverages) before a measurement. These activities can affect your blood pressure.
4) Do not be concerned with the results of one measurement. Many measurements, recorded over a long period of time will provide a better indication of both your blood pressure and / or arterial hardness.
5) Please relax for at least 5 minutes before taking another measurement.
6) Many factors can affect your blood pressure and / or arterial hardness indication, such as exercising, eating, talking, moving, nervousness, environment and temperature changes. Emotional stress can cause an increase in blood pressure, and / or the arterial hardness. Daily fluctuations of 25 to 50mmHg or up to 3 bars are common for many people.
7) Remember that blood pressure and arterial hardness vary continuously throughout the day. Try to take your arterial hardness reading at the same time each day.
Correct Posture of Measurement
To obtain the most accurate blood pressure and H-Value measurement, please follow these important directions.
Be seated in a chair with back support
Rest your arm on a table to the cuff is at the same level as your heart
Place both feet on the ground.
NOTE: The arm cuff must be at the same level as your heart, or accurate measurement will not be possible. (Your heart is located slightly below your left armpit.) If the cuff is 10cm higher or lower than the heart, then the blood pressure will be 8mm/Hg lower or higher.
Battery Installation / Replacement
1) Flip open the batter cover in the direction of the arrow
2) Install or replace the four alkaline AA batteries, noting the proper orientation of positive and negative terminals of the batteries in the battery compartment.
3) Replace the batter cover
4) If the Low Battery Symbol appears on the display, replace all batteries with new ones. Do not mix with any old battery, it will cause the new batteries to die very quickly.
5) Remove the batteries if the unit will not be used for an extended period of time.
Note: Batteries are hazardous waste. Do not dispose with the household garbage.
Note: The following battery replacement procedure will help you keep the measurement memory, inflation level and the date / time setting.
1) Replace one battery at a time. You have about 10 seconds for changing each battery before the memory and other settings are deleted.
2) Do not touch any button when charging the battery.
Setting Date and Time
For saving subsequent measurements with correct date and time, you have to set date and time after installation of batteries.
1) After the batteries have been properly installed, “0:00” and “1-1” will appear as time and date respectively.
2) Press the Mode button repeatedly; the individual figure will start blinking sequentially from month, day, hour, then to minute.
3) After you have selected a desired column (month, day, hour or minute), indicated by the blinking digit, press the Adjust button to make adjustment to the current date and time.
4) After setting the correct date and time, press the Mode button or Start / Stop button to exit the date / time setting mode.
Note: When the batteries are removed from the device, date / time needs to be set again.
How to Apply the Arm Cuff
(Preferably on the left arm)
1) Insert the end of the cuff through the metal D-ring to make a loop (Make sure that the Velcro stays outside when it is done)
2) Wear the arm cuff with the hose downward. Pull the end of the cuff and secure it snugly with the Velcro.
3) Adjust the cuff that the bottom edge is about 1 inch above the elbow on the inside of the left arm. Pelase mind the red button on the cuff covers the brachial artery.
4) Plug in the air tube connector tightly to the monitor.
Setting Inflation Level
Press Adjust button to select the proper inflation level. There are 3 preset levels: 180, 210 and 240 mm/Hg. Start taking measurements with the level 180 mm/Hg. If the setting is too low, the device will automatically re-inflate to a higher setting. If the device re-inflates every time you take a reading, you are advised to set the inflation level one level higher. It is not necessary to set inflation level every time you take a reading. If you do not change the inflation level, the unit will inflate to the level set previously.
By removing the batteries, the unit will reset the pressure setting to 180 mm/Hg.
Taking a Measurement
Please review the previous sections on proper placement of the cuff and proper arm position.
1) After the cuff has been properly placed on either the right or left arm, press the Start / Stop button. All symbols on the LCD display will appear momentarily follow by inflation level.
2) After the display reads “0”, the cuff will automatically inflate to the preset pressure, and will then begin to slowly deflate.
Note: If a downward arrow sign is displayed instead, unplug the tube and press the cuff to force out the remaining pressure. Plug the tube and continue.
3) The heart symbol will appear indicating that the measurement is in progress. The cuff will be quite snug for a short while, this is normal. Try to remain relaxed, refrain from talking, and be as still as possible during the measurement.
4) After a successful measurement, the unit deflates the cuff and displays the result on the LCD.
Note: to end a measurement for any reason, just press Start / Stop button to turn off the unit and the cuff pressure will be released.
Note: If during a measurement the power drops to an insufficient level, the unit will end the measurement and display the low battery symbol. Please replace the batteries (alkaline type).
Note: If the unit cannot detect your pulse, it will end the measurement attempt. It could be that the cuff was put on loosely. Relax for a few minutes, make sure that the cuff is put on properly and try again.
Note: The unit will automatically shut off 3 minutes following a reading, or it can be turned off manually by pressing the Start / Stop button.
Arterial Hardness Indicator
After your first blood pressure reading, the unit displays your arterial hardness average in the Arterial Hardness Indicator section of the LCD display with current date and time when you turn off the unit. For more information on Arterial Hardness Indicator please refer to Part One: User’s Guide.
This unit has a memory feature. When a valid measurement is made, the data is stored in the memory automatically when the unit is turned off, automatically shuts off, or when another measurement is initiated.
The unit is capable of storing 30 readings and computes the average from all the reading results in memory. When the 30 memories are full, the oldest records will be deleted as the new readings are being recorded, and the memory will maintain a moving average of the latest 30 readings.
To recall your readings, press the Memory button. The average will be displayed first, indicated by No-A on the upper right hand corner. Two seconds later the Date / Time will be displayed. After alternatively displayed twice, the unit will exit memory mode and Return to Arterial Hardness Indicator display if the Memory button is not pressed again before it exits the memory mode.
Note: Smaller memory number represents newer entry. Up to 30 previous readings can be recalled. You may press the Start / Stop button at any time to exit memory mode and return to stand-by mode.
If you let anyone else use this unit, that person’s reading result will be stored. To prevent memory mix up, you should erase that person’s reading record(s). To erase a record, press the Memory button to enter the memory mode. Press it again to see “No-1” shown on the display. Press and hold the Adjust button until you see “clr” appears on the display. The device will return to stand-by mode automatically, which is an indication that you have successfully erased the record. Repeat the same procedure if that person took more than one reading. No matter how many readings a person takes, you would always erase the record that display “No-1”. For example, if you took three readings, you would erase record “No-1” three times.
Note: when taking a measurement, the memory button is inactive.
Note: When the batteries are removed from the device, all records of reading will be erased. If you want to keep the memory and other settings, please refer to the Battery Installation / Replacement section.
