numbers in blood pressure meaning
What does the diastolic blood pressure number mean? The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats. A normal diastolic blood pressure number is 80 or less. A diastolic blood pressure between 80 and 89 is normal but higher than ideal. A diastolic blood pressure number of 90 or higher, on repeated measurements, is considered to be hypertension or high blood pressure.
80/60 - 90/60. Readings at or below 90/60 usually indicate low blood pressure, or what's called HYPOTENSION, meaning the pressure in your arteries is at the lower end of what's considered normal. Some people with blood pressure this low may be prone to weakness or fainting, but many people feel just fine.
The first number is the systolic pressure, when your heart pushes blood around your body. The second is the diastolic pressure, when your heart relaxes. Blood pressure usually ranges between 90 to 250 for the top or maximum number (systolic) and 60 to 140 for the bottom or minimum number (diastolic). A healthy blood pressure is 120/80 or less, but the lower you can get it, the better.
