<s>[INST] HOW DO I KNOW WHAT MY BLOOD PRESSURE IS? [/INST] Blood pressure is measured with two factors: systolic (when the heart contracts) and diastolic (when the heart is filling).  When your doctor tells you your blood pressure, they will say “number over number”.  The first number is systolic, the second is diastolic.  You may see the symbol “mmHg” or “mm Hg” next to your blood pressure reading.  This stands for a millimeter of mercury and it is the unit with which blood pressure is measured.
