Refer to the following table for classifying blood pressure values (units: mmHg) according to the Canadian Heart
and Stroke Foundation:
Category
Optimal
Normal
High Normal
High Blood Pressure
(measured in a doctor's office)
High Blood Pressure
(when home monitoring)
Isolated Systolic Hypertension
Important for Canadians: Hypertension Canada recommends that patients with average
measurements of 135 mmHg (systolic) or 85 mmHg (diastolic) at home be considered
hypertensive. Should your average readings be in this range, consult your physician.
For further information, see our website www.biosmedical.com.
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". In any case,
please discuss the values with your doctor.
Correctly measured diastolic blood-pressure values above 120 mmHg require immediate medical treatment.

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.
