Let’s first take a look at what drives your blood pressure. Unlike a river, which flows continuously downstream, blood flow is pulsatile, with ebb and flow driven by pumping heart muscle. This cycle repeats itself 60 or so times each minute, every time your heart beats. With each heartbeat occurring about once per second, the heart squeezes, or contracts, within a split-second. The rapid contraction forces about 90 cc of blood (approximately 1/3 cup) up, pushing the aortic valve open, and blood passes up into the aorta and rapidly distributes upward to the brain (via the carotid arteries on either side of the neck), the arms, and downward to the abdomen, pelvis, and legs. The force of heart contraction and its rapid distribution to the body is measured as systolic pressure, or the top number in blood pressure. As the 90 cc or so of ejected blood distributes rapidly throughout the body, pressure in all the arteries drops over the ensuing half second, and the aortic valve closes. Th...
