Frequently Asked Questions
What do blood pressure numbers mean?▾
Blood pressure is measured with two numbers: systolic (top number) measures the pressure when your heart beats, and diastolic (bottom number) measures the pressure when your heart rests between beats. A reading of 120/80 mmHg is considered the upper limit of normal.
What are the AHA blood pressure categories?▾
The American Heart Association defines five categories: Normal (less than 120/80), Elevated (120-129/less than 80), High Blood Pressure Stage 1 (130-139 or 80-89), High Blood Pressure Stage 2 (140+ or 90+), and Hypertensive Crisis (higher than 180 and/or higher than 120).
What is Mean Arterial Pressure (MAP)?▾
Mean Arterial Pressure is the average pressure in your arteries during one cardiac cycle. It is calculated as diastolic + one-third of pulse pressure. A normal MAP is typically between 70 and 100 mmHg.
How often should I check my blood pressure?▾
The AHA recommends that adults with normal blood pressure have it checked at least once a year. Those with elevated or high blood pressure should check more frequently as advised by their healthcare provider.
