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.
What Is It? If you subtract the smaller blood pressure number from the larger one you get a number which is the Pulse Pressure. For example, a blood pressure of 120 over 80 yields one of 40 mm Hg (120 minus 80 = 40). Obviously it is the difference between the systolic and the diastolic pressures. Let's call it PP. Thus there are three components to this (or any other) blood pressure reading: Systolic pressure (120), diastolic pressure (80) and pulse pressure (40). SBP, DBP and PP.
