Important Instructions Before Use
1. Do not confuse self-monitoring with self-diagnosis. Blood pressure
measurements should only be interpreted by a health professional who
is familiar with your medical history.
2. If you are taking medication, consult with your physician to determine
the most appropriate time to measure your blood pressure. NEVER
change a prescribed medication without first consulting with your
physician.
3. Blood pressure can vary based on many factors, including age, gender,
weight and physical condition. In general, a person’s blood pressure is
lower during sleep and higher when he or she is active. Blood pressure
can change easily in response to physiological changes. The setting in
which a person’s blood pressure is measured can also affect the results.
Having one’s blood pressure measured by a healthcare professional in a
hospital or clinic can cause nervousness and may result in a temporarily
elevated reading. Because blood pressure measurements taken in a
clinical setting can vary considerably from those taken at home, a
person’s blood pressure should be measured not only occasionally in
the doctor’s office, but also on a regular basis at home. Also, if you find
that your blood pressure is lower at home, this is not unusual. To
accurately compare with your physician’s reading, take your National
blood pressure meter to your doctor’s office and compare readings in
this setting.
4. People suffering from cardiac arrhythmia, vascular constriction, liver
disorders or diabetes, people with cardiac pacemakers or a weak pulse,
and women who are pregnant should consult their physician before
measuring their blood pressure themselves. Different values may be
obtained due to their condition.
5. Try to take your blood pressure measurements at the same time and
under the same conditions every day.
• The ideal time to measure your blood pressure (to obtain your so-called
“base blood pressure”) is in the morning just after waking up, before
having breakfast and before any major activity or exercise. If this is not
possible, however, try to take measurements at a specified time prior to
breakfast, and before you have become active. You should relax for
about 5 minutes before taking the measurement.
• The following situations may cause substantial variations in blood
pressure readings and should therefore be avoided at least 30 minutes
prior to taking your blood pressure.
Blood pressure will be higher than usual:
- when you are excited or tense
- when you are taking a bath
- during exercising or soon after exercising
- when it is cold
- within one hour after eating
- after drinking coffee, tea or other beverages containing caffeine
- after smoking tobacco
- when your bladder is full
Blood pressure will be lower than usual:
- after taking a bath
- after drinking alcohol
