APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Blood pressure is measured as two numbers: Systolic blood pressure (the first and higher number) measures pressure inside your arteries when the heart beats. Diastolic blood pressure (the second and lower number) measures the pressure inside the artery when the heart rests between beats.

Detailed explanation-2: -The top number (systolic) minus the bottom number (diastolic) is the pulse pressure. For example, if the resting blood pressure is 120/80 millimeters of mercury (mm Hg), the pulse pressure is 40-which is considered a healthy pulse pressure. Generally, a pulse pressure greater than 40 mm Hg is unhealthy.

Detailed explanation-3: -The diastolic pressure in a normal blood pressure reading will be between 80-90 beats per minute. You may see a normal blood pressure reading written as 124/84, for example. An even better normal blood pressure reading is anything under 120 and less than 80, like 118/78, for example.
