A FEW WORDS ABOUT BLOOD PRESSURE
Blood pressure is the force exerted on the walls of
your blood vessels as blood flows through them.
Your heart is like a pump. When it contracts,
or beats, it sends a surge of blood through
the blood vessels and pressure increases.
This is called your systolic pressure.
When your heart relaxes between beats,
your blood pressure decreases. This is
called your diastolic pressure.
When a doctor takes your blood pressure, he or she
measures both your systolic and diastolic pressures
and records them as numbers. For example, if your
blood pressure reading is 126/76 (126 over 76), your
systolic is 126 and your diastolic is 76. The numbers
are calculated in millimetres of mercury and recorded
as 126/76 mm Hg.
