Were you looking for information about Blood Pressure? Blood presure is a common misspelling of blood pressure.
Blood pressure refers to the pressure inside your blood vessels, both as your heart is pumping blood through the vessels and while the heart is relaxed. This pressure keeps the blood flowing through your body so your cells get the oxygen and nutrients they need. Keeping it at a healthy level is essential to good long-term health -- both high and low blood pressure can cause health problems.
When this pressure is measured, it is usually expressed as one number over another, like a fraction. The number on top refers to the systolic pressure, which is the pressure inside your blood vessels at the moment your heart beats. The number on the bottom measures diastolic pressure, or the pressure in your blood vessels between heartbeats, when your heart is resting.
This pressure changes frequently throughout the day. Posture, exercise, nicotine use, and other factors can all have an impact in just a few minutes. It's important to look at your overall health, diet, lifestyle, and family history when comparing your number to what's considered "normal." These factors may cause you to have a higher or lower reading than "normal."
