Detecting the “Silent Killer”: Steps to an Accurate Blood Pressure Reading
March 19th, 2013 at 10:43 am
As we age, our doctors tell us to stay active and keep a healthy lifestyle. They take our blood pressure, recite a few numbers, and possibly talk about how to change the number. But what do those numbers mean?
Blood pressure is read as a fraction (i.e. 117/76) and is measured in millimeters of mercury (mm Hg). The top number is the Systolic and is the higher of the two. This measures the pressure in the arteries when the heart beats or contracts. The bottom number is the Diastolic and measures the pressure in the arteries between beats or when the heart muscles is resting and refilling with blood1.
According to the American Heart Association (AHA), it is recommended to have your blood pressured screened every two years starting at age 20.1 If you are higher than the normal range of 120/80, talk with your doctor about more frequent screenings.
Below is the AHA’s blood pressure categories1
|Category||Systolic (upper #)||Diastolic (lower #)|
|Normal||Less than 120||And||Less than 80|
|High Blood Pressure (Hypertension) Stage 1||140-159||Or||90-99|
|High Blood Pressure (Hypertension) Stage 2||160 or Higher||Or||100 or higher|
|Hypertensive Crisis (Emergency Care Needed)||Higher than 180||or||Higher than 110|
Why is knowing your blood pressure so important?
Your BP tells you if your tissues are receiving regular supplies of blood that is rich in the oxygen it needs to function. High blood pressure (HBP) is also known as the “silent killer”. It has no symptoms. It not only damages your heart and arteries but other organs as well and can lead to serious heath problems2. Checking your blood pressure on a regular basis to ensure it falls in a healthy range protects your entire body. Further, it reduces your risk of blood vessel walls becoming overstretched or injured, lowers the risk of a heart attack, stroke or other form of heart failure3.
