DISPLAY SCREEN
LifeSource® Blood Pressure Monitors are easy to use, accurate and display clear digital measurements. Our technology is based on the “oscillometric method”. The term “oscillation” refers to the measure of vibrations caused by the arterial pulse and is a non-invasive method to determine blood pressure.
Our monitors examine the pulsatile pressure generated by the arterial wall as it expands and contracts with each heartbeat against the monitor's cuff. This monitor measures your blood pressure while the cuff is inflating.
BEFORE YOU START
The UB-521 provides accurate readings on wrists with a circumference between 5.3" and 8.5" (13.5 cm and 21.5 cm).
The unit requires two "AAA" (1.5 volt) batteries to operate (alkaline batteries recommended). To install batteries (or to replace when "Low Battery" symbol appears), proceed as follows:
- Slide the battery cover as shown to remove from the device.
- Insert batteries into designated areas ensuring a correct match with positive (+) and negative (-) terminals.
- Return battery cover by sliding back on to monitoring device.
NOTE: Rechargeable batteries will not work with this monitor.
Tips for Blood Pressure Monitoring:
Relax for about 5 minutes before measurement.
Do not smoke or ingest caffeine at least 30 minutes prior to measurement.
Remove constricting clothing and place cuff on bare wrist.
Unless your physician recommends otherwise, use left arm to measure pressure.
Do not talk during measurement.
Do not cross legs. Keep your feet flat on floor during measurement.
Now you are ready. Follow these simple steps:
- Sit comfortably in a chair near a flat surface.
- With palm facing upward, attach monitor to the inside of your left wrist and fasten securely. The top edge of the cuff should align with the crease of your wrist.
- Position your wrist so it is level with your heart, using an arm rest if needed. Positioning of the wrist at heart level is critical for accurate measurement.
- Press the START button. Your average blood pressure reading will appear with the number of measurements stored in memory (i.e. A25 = total of 25 measurements stored in memory). As the cuff pressurizes, measurement will begin and the Cuff Inflation Meter will show on the display screen. It is normal for the cuff to feel very tight.
NOTE: To stop inflation at any time, press START
- Remain still and refrain from talking or moving during reading.
-
As the cuff is inflating, the will appear to indicate that the measurement is in progress. The monitor measures your blood pressure while the cuff is inflating, so remain still. Once the pulse is detected, the symbol will flash with each pulse beat.
-
When measurement is complete, the systolic and diastolic pressure and pulse rate readings are displayed. The cuff will automatically deflate completely, releasing any remaining air.
SYSTOLIC
DIASTOLIC
- Press either START button once to turn off power. The device has an automatic power-down feature which turns off power automatically one minute after measurement is obtained.
PULSE
For the most useful blood pressure history, we recommend that you record the date and time after each measurement. The most accurate history relies not on a single or sporadic readings, but on a consistent monitoring pattern over time.
NOTE: If you wish to take your blood pressure measurement again, relax and wait 5-10 minutes to enable the flow of blood in the arm to return to normal.
NOTE: If you have poor blood circulation in winter (especially when your hands and wrists are cold), you may not get a blood pressure measurement.
The UB-521 Blood Pressure Monitor provides a blood pressure and pulse rate measurement even when an irregular heartbeat occurs. The Irregular Heartbeat symbol will appear in the display window in the event an Irregular Heartbeat has occurred during measurement. An irregular heartbeat is defined as a heartbeat that varies by 25% from the average of all heartbeat intervals during the blood pressure measurement. It is important that you relax, remain still and refrain from talking during measurements.
NOTE: We recommend contacting your physician if you see this 🤊 symbol frequently.
ABOUT CUFF INFLATION METER
The Cuff Inflation Meter is located on the left side of the display screen to tell you when the blood pressure monitor is inflating the cuff. The Cuff Inflation Meter moves up during inflation.
| Inflation in Progress Inflation/Measurement Complete | Measurement Displayed | |
 |  |  |
NOTE: The motor will inflate the cuff at a slow speed starting at 20mmHg to begin the blood pressure measurement process.
The UB-521 provides an average blood pressure reading based on the total measurements stored in memory. When taking a measurement, the average blood pressure reading will appear and the number of measurements stored in memory will flash several times before the cuff begins to inflate. The average blood pressure reading will also appear briefly when you recall the measurements stored in memory.
NUMBER OF MEASUREMENTS STORED IN MEMORY
ABOUT PRESSURE RATING INDICATOR™
The Pressure Rating Indicator™ is a feature which provides a snapshot of your blood pressure classification based on your measurements. This will let you quickly know what your blood pressure readings mean. Each segment of the bar indicator corresponds to the Seventh Report of the Joint National Committee (JNC7) on Prevention, Evaluation and Treatment of High Blood Pressure from the National Heart, Lung and Blood Institute - May 2003. For a more detailed look at this blood pressure classification, please refer to “Assessing High Blood Pressure” on page E-11.
The indicator displays a segment, based on the current measurement, corresponding to the JNC7 Classification.
NOTE: Due to other risk factors (e.g. diabetes, obesity, smoking, etc.) in addition to your blood pressure measurement, the Pressure Rating Indicator is approximate. Please consult with your physician for interpretation and diagnosis of your blood pressure measurements.
NOTE: Residents outside of the United States (e.g.. Canada and Mexico) should refer to the WHO Classification Table on page E-11 for assessment of their blood pressure measurement.
The UB-521 automatically stores up to (90) blood pressure and pulse measurements in its memory. Measurements stored in memory are assigned an index number in the order of the newest to the oldest. The oldest reading displays as "n01".
To retrieve readings, follow these simple steps:
- When the display screen is blank, press and hold the START button. While holding down the START button, you will see the average reading displayed first. You will then see the memory index number (e.g. n04) of the most recent reading followed by the measurement. Release the START button when you see the memory index number.
- The display will shut off automatically a few seconds after all of the readings are displayed. To turn off the monitor at any time, press the START button.
- The display will shut off automatically a few seconds after the readings are displayed.
If there are no measurements stored in memory, two 0s displayed vertically followed by a blinking "A00"
To clear the measurement history from memory, remove the battery from the unit and then place the battery back into the battery holder.
NOTE: Memory will be lost if batteries become low or are removed.
What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the heart contracts; diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of mercury (mmHg).
What Affects Blood Pressure?
Blood pressure is affected by many factors: age, weight, time of day, activity level, climate, altitude and season. Certain activities can significantly alter one's blood pressure. Walking can raise systolic pressure by 12 mmHg and diastolic pressure by 5.5 mmHg. Sleeping can decrease systolic blood pressure by as much as 10 mmHg. Taking your blood pressure repeatedly without waiting an interval of 5 minutes between readings, or without raising your arm to allow blood to flow back to the heart, can also affect it.
In addition to these factors, beverages containing caffeine or alcohol, certain medications, emotional stress and even tight-fitting clothes can make a difference in the readings.
■ What Causes Variations In Blood Pressure?
An individual's blood pressure varies greatly from day to day and season to season. For hypersensitive individuals, these variations are even more pronounced. Normally, blood pressure rises during work or play and falls to its lowest levels during sleep.
Fluctuation within a day (case: 35 year old male)
■ Assessing High Blood Pressure for Adults
The following standards for assessing high blood pressure (without regard to age or gender) have been established as a guideline. Please note that other risk factors (e.g. diabetes, obesity, smoking, etc.) need to be taken into consideration and may affect these figures. Consult with your physician for an accurate assessment.

What Is Hypertension?
Hypertension (high blood pressure) is the diagnosis given when readings consistently rise above normal. It is well known that hypertension can lead to stroke, heart attack or other illness if left untreated. Referred to as a “silent killer” because it does not always produce symptoms that alert you to the problem, hypertension is treatable when diagnosed early.
■ Can Hypertension Be Controlled?
In many individuals, hypertension can be controlled by altering lifestyle and minimizing stress, and by appropriate medication prescribed and monitored by your doctor. The American Heart Association recommends the following lifestyle suggestions to prevent or control hypertension:
- Don’t smoke. Have regular
■ Reduce salt and fat intake. physical checkups. - Maintain proper weight. Monitor your blood
Exercise routinely. pressure at periodic intervals.
■ Why Measure Blood Pressure at Home?
It is now well known that, for many individuals, blood pressure readings taken in a doctor's office or hospital setting might be elevated as a result of apprehension and anxiety. This response is commonly called “white coat hypertension.”
In any case, self-measurement at home supplements your doctor's readings and provides a more accurate, complete blood pressure history. In addition, clinical studies have shown that the detection and treatment of hypertension is improved when patients both consult their physicians and monitor their own blood pressure at home.
■ Answers to Why Your Readings are Different Between Home and at the Doctor's Office
Why are my readings different between home and at a doctor's office?
Your blood pressure readings taken in a doctor's office or hospital setting may be elevated as a result of apprehension and anxiety. This response is known as white coat hypertension.
When I bring my monitor to a doctor's office, why do I get a different measurement from my monitor to that taken by a doctor or nurse?
The healthcare professional may be using a different sized cuff. The size of the bladder inside the cuff is critical for the accuracy of the measurement. This may give you a different reading. A cuff too large will produce a reading that is lower than the correct blood pressure; a cuff that is too small will produce a reading that is higher than the correct blood pressure. There may also be other factors that can cause the difference in measurements.
■ Keys to Successful Monitoring:
Blood pressure fluctuates throughout the day. We recommend that you are consistent in your daily measurement routine:
• Measure at the same time every day.
- Sit in the same chair/position.
- Do not cross legs and keep your feet flat on the floor.
- Relax for 5 minutes before measurement.
- Use the correct cuff size to get an accurate reading.
- Sit still during measurement – no talking, eating or sudden movements.
- Record your measurement in a logbook.
■ Establishing Baseline Measurements
The most important method to get an accurate blood pressure measurement is consistency. To get the most benefit out of your monitor, it is important to establish a “baseline measurement.” This helps build a foundation of measurements that you can use to compare against future readings. To build this baseline measurement, devote two weeks for consistent blood pressure monitoring. This involves doing everything the same way when you measure (e.g. measuring during the same time of day, in the same location, sitting in the same chair, using the same cuff, etc.). Once you establish your baseline measurement, you can start evaluating if your measurement has been affected based on things like lifestyle changes or medication treatment.
How Do I Record My Blood Pressure?
Blood pressure readings are typically recorded with the systolic pressure written first, followed by a slash mark and the diastolic pressure. For example, 120 mmHg systolic and 80 mmHg diastolic measurements are written as 120/80. Pulse is simply written with the letter “P” followed by the pulse rate—P 72, for example. Please see the back of the manual for the blood pressure tracking record.
