Two numbers, one picture
A blood pressure reading has two parts. The top number, systolic pressure, measures the force in your arteries when your heart beats. The bottom number, diastolic pressure, measures the pressure between beats.
What the ranges mean
A reading below 120/80 mmHg is generally considered normal for adults. Readings that stay higher over time are worth discussing with your clinician, who will consider your age, health and other risk factors.
Getting an accurate reading
Rest quietly for five minutes before measuring
Sit with your back supported and feet flat
Avoid caffeine and exercise for 30 minutes beforehand
Take two readings a minute apart and note both
When to seek advice
One high reading is not a diagnosis. If your numbers are consistently raised, or you have headaches, chest discomfort or vision changes, book a review with a clinician.
