Understanding and Tracking Your Blood Pressure




Blood pressure is an important part of everyone’s health, because high blood pressure contributes to many forms of cardiovascular diseases. It benefits everyone to understand and monitor their blood pressure.

Blood pressure (BP) measures the force of the blood pushing outwards on the walls of your arteries. It rises with each heartbeat and falls when your heart relaxes between beats. It can change from minute to minute with changes in posture, activity, stress or sleep. It increases with age.

A BP reading consists of two numbers, for example: 120/80 mm Hg.

One number is always larger and refers to systolic BP, the pressure in the arteries when the heart contracts. The smaller number refers to diastolic BP, the pressure in the arteries when the heart rests between beats and refills with blood.

About one in three U.S. adults has high blood pressure (HBP). By 2030, it is expected that over 41 percent of U.S. adults will have it. Normal BP for adults age 20 or over is no higher than 120/80 mm Hg.

One blood pressure reading only tells you what your blood pressure is at that moment. A record of readings taken over time provides a “time-lapse” picture of your blood pressure that you can show your doctor to ensure that your treatments are lowering your BP. You can find an easy-to-use BP tracker at our Check. Change. Control.® website.

Monitoring your BP at home is as easy as buying a BP cuff, using it correctly and tracking the numbers. Here are some tips for what to look for in a home blood pressure monitor.

American Heart Association recommended blood pressure levels

Blood Pressure Category Systolic (mm Hg)   Diastolic (mm Hg)
Normal less than 120  and  less than 80
Prehypertension 120-139  or 80-89
High Stage 1 140-159  or 90-99
High Stage 2 160 or higher  or  100 or higher

 

Blood pressure higher than 180/110 mm Hg is an emergency.*

*Wait a few minutes and take blood pressure again. If it's still that high, seek emergency medical care.
