1. Introduction
1.1. Your automatic wrist blood pressure monitor
Thank you for purchasing a fully automatic wrist blood pressure monitor. Your monitor is
designed to provide fast and reliable digital readings of your pulse, and systolic / diastolic
blood pressure using the oscillometric method on your wrist. It offers clinically proven
accuracy and has been designed to be user friendly.
Before using your blood pressure monitor, please read this instruction manual carefully to
ensure correct use. If you have additional questions regarding blood pressure
measurements please contact your doctor.
1.2. Inflation mode technology
Please note that this device employs “Inflation Mode Technology.” This means your blood
pressure is measured while the wrist cuff is inflating, rather than first inflating to a peak
pressure, and then measuring during a slow deflation process. With this process, it is a
normal occurrence for the inflation speed to vary. This unique technology provides a faster,
more comfortable blood pressure reading for you.
If you have any questions about your blood pressure reading or monitor, please call us at
1-888-287-1915.

2. How is blood pressure measured?
2.1. What is blood pressure, and why does it fluctuate?
Your level of blood pressure is determined in the circulatory center of the brain and adjusts to
a variety of situations through feedback from the nervous system. To adjust blood pressure,
the strength and frequency of the heart (pulse), as well as the width of circulatory blood
vessels is altered.
Blood vessel width is affected by way of fine muscles in the blood vessel walls. Your level of
arterial blood pressure changes periodically during heart activity. During the "blood ejection"
(Systole), the value is highest (systolic blood pressure value). At the end of the heart’s "rest
period" (Diastole), pressure is lowest (diastolic blood pressure value). Your blood pressure
values must lie within certain normal ranges in order to prevent particular diseases.
2.2. Measurement guidelines
Blood pressure is very high if your systolic blood pressure is over 160 mmHg and/or your
diastolic pressure is above 100 mmHg, while at rest. In this case, please consult your
physician immediately. Long-term values at this level endanger your health due to continual
damage to the blood vessels in your body.
If your systolic blood pressure values are between 140 mmHg and 159 mmHg and/or the
diastolic blood pressure values are between 90 mmHg and 99 mmHg, consult your
physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values under 105 mmHg
and/or diastolic values under 60 mmHg), consult your physician. Even with normal blood
pressure values, a regular self-check with your blood pressure monitor is recommended.
You can detect possible changes in your values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, keep a record of
values along with time of day and date. Show these values to your physician.
Never use the results of your measurements to independently alter the medication
prescribed by your physician.
Which values are normal?
The following standards for assessing high blood pressure (in adults) have been established
by the American Heart Association (AHA) and American College of Cardiology (ACC) in
2017.

Additional information
• If your values are mostly normal under resting conditions but exceptionally high under
conditions of physical or psychological stress, it is possible that you are suffering from
so-called "labile hypertension." Consult your physician.
2.3. What can I do to change my blood pressure?
a). Consult your physician.
b). Increased blood pressure values (various forms of hypertension) are associated with
considerable health risks over time. Arterial blood vessels in your body are endangered
due to constrictions caused by deposits in the vessel walls (arteriosclerosis).A deficient
supply of blood to important organs (heart, brain, muscles) can result. Furthermore, the
heart will become structurally damaged with increased blood pressure values.
c). There are many different causes of high blood pressure. We differentiate between the
common primary (essential) hypertension and secondary hypertension. Secondary
hypertension can be ascribed to specific organ malfunctions. Please consult your
physician for information about the possible origins of your own increased blood
pressure values.
d). There are measures you can take to reduce and even prevent high blood pressure.
These measures must be permanent lifestyle changes.
1) Eating habits
• Strive for a normal weight corresponding to your age. See your doctor for your ideal weight.
• Avoid excessive consumption of common salt.
• Avoid fatty foods.
2) Previous illnesses
Follow consistently any medical instructions for treating illness such as:
• Diabetes (diabetes mellitus)
• Fat metabolism disorder
• Gout
3) Habits
• Give up smoking completely.
• Drink only moderate amounts of alcohol.
• Restrict your caffeine consumption (e.g., coffee).
4) Physical constitution
• After a preliminary medical examination, do regular exercise.
• Choose sports which require stamina and avoid those which require strength.
• Avoid reaching the limit of your performance.
• With previous illnesses and/or an age of over 40 years, please consult your doctor before
beginning your exercise routine. He will advise you regarding the type and extent of exercise
that is appropriate for you.
