Your blood pressure reading will show a top number and a bottom number.
The top number is your systolic blood pressure, the highest level your blood pressure reaches when your heart beats and pumps blood around your body.
The bottom number is your diastolic blood pressure, the lowest level your blood pressure reaches as your heart relaxes between each beat.
Your reading will be measured in millimetres of mercury (mmHg) - the ideal blood pressure reading is between 90/60mmHg and 120/80mmHg.
