1. Introduction
Thank you for purchasing the BIOS Diagnostics™ Ultra Blood Pressure Monitor with Atrial Fibrillation
Screening. Designed for convenient and easy operation, this device provides a simple, yet accurate
method to measure your blood pressure.
Your blood pressure is an important parameter that can be used to monitor your health. This device
enables you to monitor your blood pressure regularly, and maintain a record of your blood pressure
measurements. You can then use this record to assist your physician in diagnosing and maintaining a
healthy blood pressure level.
1.1 Features
The BD350 is a fully automatic, digital, blood pressure measuring device with a unique fuzzy logic
technology as well as patented MAM and AFIB technologies. It can store up to 200 blood pressure
readings.
It provides a fast and reliable measurement of systolic and diastolic blood pressure as well as heart rate
using the oscillometric measurement method.
AFIB detection is the world’s leading digital blood pressure measurement technology for the early
detection of atrial fibrillation (AFIB) and hypertension. These are the two top risk factors of heart disease
and stroke which increase the risk of getting a stroke or heart disease in the future. It is important to
detect AFIB and hypertension at an early stage, even though you may not experience any symptoms.
Appropriate treatment can reduce your risk of suffering a stroke. For this reason, it is recommended that
you visit your doctor when the device gives an AFIB signal during your blood pressure measurement. The
AFIB algorithm has been clinically investigated by several prominent clinical investigators and showed
that the device detects patients with AFIB at 97-100% certainty.
• MAM - Averaging Mode technology used in the device provides accurate measurements. Using
three consecutive measurements, your result is calculated and displayed as a single averaged
measurement on the display screen.
• AFIB - Atrial Fibrillation Detection technology icon is displayed when atrial fibrillation is detected
during a blood pressure reading.
• Blood Pressure Analyzer Software allows you to download, record and chart your readings to
accurately monitor your daily readings. The Blood Pressure software can be downloaded for free from
www.biosmedical.com
This powerful medical tool automatically stores all your blood pressure readings. By clicking the
viewing options the user can review the readings in multiple forms including: by date, morning vs.
evening readings, isolated systolic or diastolic or pulse. The automatic graph clearly shows your
blood pressure history with highs and lows. Charts and graphs can even be printed or emailed to your
doctor!
This device is easy to use and has been proven in clinical studies to provide excellent accuracy. Before
using the BD350, read this instruction manual carefully and keep it in a safe place.

1.2 Important Information
Refer to the following sections to learn about important safety instructions and how to take care of the
BIOS Diagnostics™ Ultra Blood Pressure Monitor with Atrial Fibrillation Screening.
1.2A Safety Information
• Self-measurement means control, not diagnosis or treatment. Your values must always be discussed
with your doctor or a physician who is familiar with your family history.
• If you are undergoing medical treatment and receiving medication, consult your doctor to determine
the most appropriate time to measure your blood pressure. Never alter the dosages of any medication
without direction from your doctor.
• Your blood pressure depends on several factors, such as age, gender, weight and physical condition. It
also depends on the environment and your state of mind at the time of measurement. In general, your
blood pressure is lower when you are asleep and higher when you are active. Your blood pressure may
be higher when recorded at a hospital or a clinic and may be lower when measured in the relaxing
comfort of your home. Due to these variations, we recommend that you record your blood pressure
regularly at home as well as at your doctor’s clinic.
• Try to record your blood pressure regularly at the same time of the day and under the same conditions.
This will help your physician detect any extreme variations in your blood pressure and thus treat you
accordingly.
• Morning Hypertension (> 135 / 85 mmHg): Recently, several studies have identified elevated
cardiovascular risks (heart failure, stroke, angina) associated with “morning hypertension”. There is a
typical rise in blood pressure during the physiological changes from sleep to arising for the day.
• The ideal time to measure your blood pressure is in the morning just after you wake up, before
breakfast and any physical activity, and in the absence of the urge to urinate. If this is not possible, try
to take the measurements later in the morning, before you start any physical activity. Relax for a few
minutes before you record your blood pressure.
• Your blood pressure increases or decreases under the following circumstances:
Blood pressure is higher than normal:
— When you are excited, nervous, or tense
— While taking a bath
— During and after exercise or strenuous physical activity
— When it is cold
— Within one hour after meals
— After drinking tea, coffee, or other caffeinated drinks
— After smoking tobacco
— When your bladder is full
Blood pressure is lower than normal:
— After consuming alcohol
— After taking a bath

• The pulse display is not suitable for checking the frequency of heart pacemakers.
• If you have been diagnosed with a severe arrhythmia or irregular heartbeat, vascular constriction,
liver disorders, or diabetes, have a cardiac pacemaker, or are pregnant, measurements made with this
instrument should only be evaluated after consultation with your doctor.
• Take care while handling the batteries in the device. Incorrect usage may cause battery fluid leakage.
To prevent such accidents, refer to the following instructions:
— Insert batteries with the correct polarity.
— Turn off power after use. Remove and store the batteries if you are not planning to use the device
for an extended period of time.
— Do not mix different types, brands, or size of batteries. This may cause damage to the product.
— Do not mix old and new batteries.
— Remove batteries and dispose of them according to the proper regulations in your area.
— Do not disassemble batteries or expose them to heat or fire.
— Do not short-circuit the batteries.
— Do not use rechargeable batteries.
1.2B Care of the Device
For prolonged life of your blood pressure monitor, note the following instructions:
• Do not drop or bang the unit. Prevent sudden jerks, jars, or shocks to the device to prevent damage.
• Do not insert any foreign objects in any device openings or vents.
• Do not disassemble the unit.
• If the unit has been stored at very low or freezing temperatures, allow to reach room temperature before using it.
• Do not store the unit in direct sunlight, high humidity, or in places with a lot of dust.
• Clean the device with a soft dry cloth. Do not use gasoline, thinner or similar solvents. Carefully remove
spots on the cuff with a damp cloth and soap. Do not wash the cuff.
• Do not use the device if you think it is damaged or if anything appears unusual.
• Ensure that children do not use this device unsupervised; some parts are small enough to be swallowed.
Be aware of the risk of strangulation in case this device is supplied with cables or tubes.
• Using the unit in the immediate vicinity of mobile phones, microwave appliances or other devices with
strong electromagnetic fields may result in impaired functioning.
• Do not use this device close to strong electromagnetic fields, such as mobile telephones or radio
installations. Keep a distance from such devices when using this unit.
1.2C Comparing Readings to Other Blood Pressure Devices
Many questions arise when two blood pressure devices are compared in an effort to check accuracy. An
accurate comparison requires repeatable measurements under the same conditions, and significant time
is required to reduce naturally occurring blood pressure variability during the test. For proper comparisons,
the subject should be seated comfortably with feet flat on the floor, and have rested for 5 minutes before
the first reading to allow blood pressure levels to stabilize. The patients back, elbow and forearm should
be supported, and the middle of the cuff should be at the level of the right atrium. There should be no
talking or moving during the measurement and if comparing to an aneroid gauge or mercury column,
observers should avoid parallax and be careful not to round measurements.

The most accurate way to compare devices is to take two readings at the same time. However most
people and doctor’s offices do not have the equipment necessary to measure blood pressure from two
devices simultaneously. To take sequential measurements properly requires a pair of initial measurements
to determine the subjects blood pressure level: first with the reference equipment, followed by 60 seconds,
then with the monitor-under-test. The actual accuracy test requires three pairs of measurements with 60
seconds between measurements. These measurements are averaged and a comparison can be made.
Since most people tend to relax and their blood pressure falls with subsequent measurements, following
this protocol reduces these natural changes in blood pressure levels.
The standard technical error of both consumer and professional devices is normally ±3 mmHg, so a
discrepancy of 6 mmHg is acceptable even when the devices are working within their specifications.
Any comparisons without following the procedures described above will not yield reliable results.
In addition, to do an accuracy test properly the reference device must also be tested to a known reference
to confirm its accuracy, prior to being used as the reference for comparisons.
1.2D Calibration
Digital blood pressure monitors do not require recalibration. If the unit turns on and does not display an
error code, the product is working properly. In extremely rare cases, the cuff may have developed a pin-hole
leak, or the gasket where the cuff connector enters the monitor may not have a proper seal; both of these
leaking air issues will potentially cause errors in accuracy, but otherwise the product will work accurately
without drifting out of calibration.
1.3 What do your Numbers Mean?
Blood pressures is the pressure in your blood vessels while blood circulates throughout your body. High
blood pressure or “Hypertension” is the pressure at which ones normal average blood pressure is considered
too high and other health risks including: heart attack, stroke, dementia, kidney failure, heart disease and
erectile dysfunction may occur. It is expressed as two numbers: systolic/diastolic 120 mmHg/ 80 mmHg
(mmHg= millimeters of mercury). “Systolic” numbers refer to the pressure on the walls of your arteries while
the heart is contracting and pushing blood. “Diastolic” pressure is the lower number when the heart is at
rest and relaxed. A simple way to understand this is to picture a garden hose. When the tap is turned on, the
immediate pressure on the walls of the hose is the “systolic” value, and when the tap is turned off it is the
“diastolic” number.
There are many different causes of high blood pressure. We differentiate between common primary
(essential) hypertension, and secondary hypertension. The latter group can be ascribed to specific organic
malfunctions. Please consult your doctor for information about the possible origins of your own increased
blood pressure values.

1.4 Normal Blood Pressure Values
Blood pressure is too high when measuring at home and you have rested, the diastolic pressure is above
85 mmHg or the systolic blood pressure is above 135 mmHg. If you obtain readings in this range, consult
your doctor immediately. High blood pressure values over time can damage blood vessels, vital organs
such as the kidney, and your heart.
With blood pressure values that are too low (i.e., systolic values under 105 mmHg or diastolic values
under 60 mmHg), consult with your doctor.
Systolic Diastolic Comment
Below 120 Less than
80 This range is considered “Normal” and ideal
120 – 139 80 – 89
This range is considered “Pre-hypertension”: Discuss with your health
care professional. Lifestyle modifications maybe required to avoid
advancing into Hypertension.
140 – 159 90 – 99
This is in the hypertension range. Discuss with your health care
professional. Medication(s) and lifestyle modifications are typical
treatments.
160 and
higher 100 + Discuss with your medical professional, medication(s) and lifestyle modifications are necessary to control your hypertension
Adopted From: Understanding and Managing your blood pressure; Hypertension Canada.
Note: A diagnosis of high blood pressure must be confirmed with a medical professional. A
doctor should evaluate any unusual blood pressure readings. Additionally, lower targets may
be appropriate for some populations such as African-Americans, the elderly, or patients with
underlying issues such as diabetes mellitus or chronic kidney disease.
Important for Canadians:
* Hypertension measured at home ≥135/85
* Hypertension measured at a physician’s office ≥140/90
* Hypertension measured at a physician’s office for a diabetic patient ≥130/80

1.5 Common Blood Pressure Questions and Answers
a) Why is my blood pressure reading always different?
Your blood pressure changes constantly. It is quite normal for blood pressure to fluctuate significantly (50
mmHg to 60 mmHg) throughout the day. Blood pressure is normally lowest at night, but increases during
waking hours when the stress and activities of everyday life are highest.

b) Why is the doctor’s reading different from the reading taken at home?
Your blood pressure can vary due to the environment (temperature, nervous condition). When measuring
blood pressure at the doctor’s office, it is possible for blood pressure to increase due to anxiety and
tension, this is known as “White Coat Hypertension”.
c) Why should I monitor blood pressure at home?
One or two readings will not provide a true indication of your normal blood pressure. It is important to
take regular, daily measurements and to keep records over a period of time. This information can be used
to assist your physician in diagnosing and preventing potential health problems.
1.6 About MAM Technology
(Average Mode) technology is a new technology that enables optimum reliability in self-measurement of
blood pressure.
An advanced measurement accuracy is achieved by the automatic analysis of three successive
measurements, with short rest periods in between (see diagram 1 in section 1.6D).
This new technology provides reliable values for the doctor and can be used as the basis for reliable
diagnostics and medication therapy for high blood pressure.
• Reliable patient self-measurement data for the doctor
• Safe hypertension diagnostic tool
• Reliable therapy control

1.6A Why Use MAM?
• Human blood pressure is not stable
1.6B Key Advantages
The technology provides reduction in:
• Device scattering
• Insufficient rest prior to measurement
• Movement effects (i.e. coughing, talking, movement)
• Cuff positioning influences
1.6C Medical Benefits
• Improved accuracy
1.6D Measurement Sequence
• Single results are not displayed
• Due to the “Data Analysis” result, a 4th or 5th measurement may be applied. The following illustration
provides a flow chart of the MAM Sequence
1.7 Important facts about Atrial Fibrillation (AFIB)
1.7A What is Atrial Fibrillation (AFIB)?
Normally, your heart contracts and relaxes to a regular beat. Certain cells in your heart produce
electrical signals that cause the heart to contract and pump blood. Atrial fibrillation occurs when rapid,
disorganized electrical signals are present in the heart’s two upper chambers, called the atria; causing
them to contract quickly and irregularly (this is called fibrillation). Atrial fibrillation is the most common
form of heart arrhythmia or irregular heart beat. You can live with atrial fibrillation, but it can lead to other
rhythm problems, chronic fatigue, heart failure and - worst of all - a stroke. You will need a doctor to help
you control the problem.
1.7B How does AFIB impact my family or me?
One in every six strokes is AFIB-related. While individuals above the age of 65 are more likely to have
AFIB, individuals as young as 40 can exhibit AFIB. Early diagnosis can help reduce the risk of a stroke.
Diagram 1

1.7C AFIB detection provides a convenient way to screen for AFIB
(only in MAM mode)
Knowing your blood pressure and knowing whether or not you or your family members have AFIB can help
reduce the risk of stroke. AFIB detection provides a convenient way to screen for AFIB while taking your
blood pressure.
1.7D Risk factors you can control
High blood pressure and AFIB are both considered «controllable» risk factors for strokes. Knowing your
blood pressure and knowing whether or not you have AFIB is the first step in proactive stroke prevention.

3.2 Measurement Mode Selection (MAM or Single)
Clinical studies demonstrate taking multiple blood pressure readings and calculating an “average” is
more likely to determine your true blood pressure. Your premium blood pressure unit allows you to switch
the unit to an Average Mode setting that automatically takes multiple readings!
Average Mode Slide Switch (MAM):
a) If you would like to take an Average Mode measurement, move the slide switch to
the right.
b) Average Mode takes 3 measurements in succession and calculates the result and
displays it as a single average measurement. A symbol in the display indicates that the unit is
set to the Average Mode.
c) There will be 15 seconds resting time in-between each measurement. The unit will count down
from 15 seconds. A beep will sound at the last 5 seconds to remind you that the unit is about to take
another measurement. If one of the measurements causes an error message, it will be repeated
one more time. If any additional error occurs the measurement will be discontinued and error code
displayed.
Note: AFIB detection can only be done in MAM mode.
Single Mode
a) If you would like to take a single mode measurement, please move the slide
switch to the left.
b) Single mode only has 1 measurement.
3.3 Obtaining Accurate Measurements
Your blood pressure can vary based on numerous factors, physiological conditions, and your surroundings.
Follow these guidelines to obtain accurate and error-free measurements of your blood pressure and pulse rate.
TIME

3.3A Tips on Taking Accurate Measurements
In morning before breakfast, 2
hours after dinner, before taking
medication.
Avoid coffee and smoking within the
hour, and no exercise 30 minutes
before measuring.
Do not speak while taking the
measurement.
Sit with legs uncrossed so as not to
restrict blood flow.
Empty bladder (if necessary).
Rest quietly for 5 minutes.
Remain calm and quiet while the
measurement is in process.
Take measurements on the non
dominant arm.
Sit with back supported and
measurement arm resting on a table.
Sit with feet flat on the floor.
Ensure that the cuff is level
with the heart while the arm is
supported on the table.
3.3B Common Sources of Error
All efforts by the patient to support the arm can increase the blood pressure. Make sure you are in a
comfortable, relaxed position and do not activate any of the muscles in the measurement arm during the
measurement. Use a cushion for support if necessary.
ATTENTION!
Comparable blood pressure measurements always require the same conditions with a peaceful and
calm environment. Ensure that you take measurements under the same conditions to obtain an accurate
estimate of blood pressure variation patterns.
• If the arm artery lies considerably lower or higher than the heart, an erroneous value of blood pressure
is measured. Each 15 cm difference in height results in a measurement error of 10 mmHg.
• A loose cuff causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results.
Consecutive blood pressure measurements should be repeated after at least a 15 second pause or
after the arm has been held up in order to allow the accumulated blood to flow away.
3.3C Fitting the Wide Range Cuff
a) Put the end of the cuff (with fastener) through the metal
ring, making the cuff a cylinder. (Ignore this step if your cuff
is already set up.) Proper assembly allows the Velcro®to
match up properly.
a)

b) Place the cuff around your bare arm. Make sure the bottom
edge of the cuff is about 1” (2-3 cm) above the elbow joint.
Adjust the cuff so that the rubber tubing under the cuff lies
over the brachial artery, which runs on the inside of the arm
(see Fig. B). The red material should be over the
brachial artery.
c) Pull the cuff and tighten it by attaching the Velcro®fastener.
Measure on your non-dominant arm, unless there is a >10
mmHg difference with the other arm, in which case use the
arm with the higher pressure.
d) The cuff should fit snugly around your bare arm, but not too
tight. You should be able to fit two fingers under the cuff.
If the cuff is the wrong size, the deivce will not measure
your blood pressure accurately. Contact the store, or BIOS
Medical for other sized cuffs.
e) Place your arm on the table (palm facing upwards) so that
the cuff is at the same level as the heart. Make sure there
is no kink in the hose.
f) You can adjust the level of your arm by putting a cushion
under your arm. Ideally the cuff should be at heart level.
g) Remain seated in a comfortable room temperature for at
least 5 minutes, then start the measurement.
h) For those who cannot put the cuff on their left arm, put it on
their right arm as shown.
e)
f)
d)
b)
c)
h)

i) Consecutive measurements will cause blood
accumulation in the lower arm which will affect the
measuring results. To improve reading accuracy, raise
the arm being measured, squeeze and relax your hand
several times, then take another measurement. Another
option is to take the cuff off and wait at least 5 minutes
before repeating measurement.
j) If this device was stored in low temperature, it is necessary to leave it in room temperature for at
least 1 hour, otherwise the measurement can be inaccurate.
Comment:
Continue to use the same arm for comparisons. It is not unusual for there to be a difference in blood
pressure between arms.
Comparable blood pressure measurements always require the same conditions (Relax for several minutes
before taking a measurement).
ATTENTION: Do not use a cuff other than the original cuff contained in this kit!
3.4 Measuring Your Blood Pressure
After following the guidelines described in the previous section and placing the cuff around your upper
arm, you are now ready to measure your blood pressure. Follow these steps to record your measurement.
1. Press the button to turn on the device and start measurement. The LCD screen is turned on. The
cuff begins to inflate while the increasing cuff pressure is displayed on the screen. After the suitable
inflation pressure is reached, the cuff stops inflating and the pressure gradually falls. A long beep
sounds when the measurement is completed. The systolic and diastolic blood pressure values along
with the pulse rate are displayed on the screen. The measurement is displayed for approximately 1
minute.
2. Switch off the device by pressing the button to preserve the batteries. If no button is pressed for 1
minute, the instrument switches the display off.
NOTE: The time will continuously be displayed on the screen.
3.5 Appearance of the Atrial Fibrillation Indicator (only in MAM mode)
This symbol indicates that atrial fibrillation was detected during the measurement. If AFIB is
present during blood pressure measurement, the AFIB Indicator is displayed. The AFIB will flash
8 times rapidly once the measurement is complete and then stop flashing. In this case, the result may
deviate from your normal blood pressure. It is highly recommended to take an additional measurement
an hour later to increase the specificity of the detection. In most cases, this is no cause for concern.
However, if the symbol appears on a regular basis (e.g. several times a week with measurements taken
daily) we advise you to visit your doctor. Please, provide the following explanation:
i)

Information for the doctor on frequent appearance of the atrial fibrillation indicator
This instrument is an oscillometric blood pressure monitor that also analyses pulse frequency during
measurement. The instrument is clinically tested.
The symbol is displayed after the measurement, if atrial fibrillation occurs during measurement. If
the symbol appears more frequently (e.g. several times per week on measurements performed daily) we
recommend the patient to seek medical advice. The instrument does not replace a cardiac examination,
but serves to detect atrial fibrillation at an early stage.
• Sometimes the device will detect atrial fibrillation even when it is not there. This can happen if the
arm moves during the reading or another rhythm problem is present. Keep the arm still during the
reading. Visiting your doctor with this device may be necessary to check out any rhythm problems.
• This device may not detect atrial fibrillation in people with pacemakers or defibrillators.
3.6 Viewing Previously Recorded Values
The blood pressure monitor automatically stores your measurements. It can store up to 200
measurements. When more than 200 measurements are made, the oldest readings are deleted to make
space for the new ones.
To view the previously stored values, press the button. The last measurement is displayed. The date
and time of the measurement are also displayed after the reading. Press the button repeatedly to view
all the measurements that are recorded on the device.
Note: Blood pressure measurements are not stored when an error is encountered during
measurement.
3.7 Clearing All Values
If you are sure that you want to permanently remove all stored values, hold down the
button (the instrument must have been switched off before hand) until the “ ” appears
and then release the button. If you do not want to clear the values, press the button. To
permanently clear the memory, press the button while “ ” is flashing. Individual values
cannot be cleared.
3.8 Discontinuing a Measurement
If it is necessary to interrupt a blood pressure measurement for any reason (e.g. the patient feels
unwell), the button can be pressed at any time. The device then immediately lowers the cuff pressure
automatically.

4. Software Functions
