Some Basics...
- Blood pressure (BP) measures the force of blood pumped by the heart on arteries. Arteries are blood vessels that carry blood away from the heart to the body. High BP can cause damage to body organs.
- Readings from home BP measurement devices are not always right. BP should be checked in both arms. Check another adult’s BP to see if the device is working. If it is still not clear that the machine is working, have BP checked by a doctor.
- If hypertension is not treated, it may cause heart, brain, kidney, or eye problems. Treating high BP can decrease the risk of stroke, heart attack, and heart failure.
What is Hypertension?
Hypertension and high blood pressure mean the same thing. An adult has hypertension if most of his or her BP readings are greater than 140/90. This means that the systolic BP is over 140 or the diastolic BP is over 90.
What Do the Words "Systolic" and "Diastolic" Mean?
The BP reading is written as two numbers. The two numbers are the systolic pressure and the diastolic pressure. If a person has a BP of 130/65, then 130 is the systolic BP and 65 is the diastolic BP. Systolic pressure is the BP when the heart beats. Diastolic pressure is the BP when the heart is resting between beats.
How is Blood Pressure Classified in Adults?
- Normal: Less than 120/80
- Pre-hypertension: Between 120-139/80-89
- Hypertension - Stage 1: Between 140-159/90-99
- Hypertension - Stage 2: Greater than 159/99
