MEDICAL PHYSIOLOGY

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: -Inflate the cuff to about 30 mmHg above the pressure at which the pulse disappears. Deflate the cuff slowly. While deflating the cuff a pulsatile thrill can be palpated, the pressure at which thrill appears is a systolic pressure and, the disappearance of the thrill is the Diastolic Blood Pressure.

Detailed explanation-3: -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-4: -Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
