Know Your Numbers: Blood Pressure Basics
High blood pressure is sometimes called a silent condition: most people feel completely fine. Over time, though, it puts extra strain on the heart, blood vessels, kidneys and brain. Knowing your numbers is the first step.
What the two numbers mean
A reading like 128/82 has two parts. The top number (systolic) is the pressure when your heart beats. The bottom number (diastolic) is the pressure between beats.
The standard categories
These are the adult categories used by the American Heart Association:
- Normal: below 120 and below 80
- Elevated: 120 to 129 and below 80
- Stage 1 high blood pressure: 130 to 139, or 80 to 89
- Stage 2 high blood pressure: 140 or higher, or 90 or higher
A reading above 180/120 is a reason to contact your provider right away. If it comes with chest pain, shortness of breath, weakness, vision changes or trouble speaking, call 911.
How to check at home
- Sit quietly for five minutes first, back supported and feet flat on the floor.
- Rest your arm at heart level and use a cuff that fits your upper arm.
- Skip caffeine, exercise and smoking for 30 minutes before.
- Take two readings a minute apart, at about the same time each day, and write them down.
Some people's numbers run higher in a medical office than at home. Comparing the two gives the truest picture.
