Key Facts

What is Blood Pressure?

Blood pressure is the force of your blood pushing against the walls of your arteries. Arteries are the vessels that carry oxygen-rich blood from your heart to the rest of your body. Every time your heart beats, it pumps blood into the arteries. This pressure is highest when your heart pumps blood out to the body, this is called systolic pressure. When your heart rests between beats, your blood pressure falls. This is called diastolic pressure.

Blood pressure is recorded as two numbers. The top number is the systolic pressure (the higher number) and the bottom number is the diastolic pressure (the lower number). For example, 120/80 mmHg means 120 millimeters of mercury systolic and 80 millimeters of mercury diastolic.
