Dylan Pointon ® - i don't know where you are going with this question but the average blood pressure is between 90/60-120/80 Anything lower is hypotension anything higher than about 130/80 is stage I Hypertension
John W - When they use the cuffs, they are actually measuring the air pressure in the cuff at the point where blood begins flowing and at what pressure it's unimpeded thereby implying what the blood pressure might be. A Doctor or nurse will use a stethoscope and watching the movements on the gauge to determine when the blood is flowing again while an automated machine will just use the variation in the air pressure as an indication to when blood is flowing. Unless they go in with a catheter as during an angiogram, they can't actually measure the real blood pressures.
jon c - Blood pressure consists of two measurements. One is when the heart is relaxed, which is 2/3rds of the time. This number corresponds to diastolic pressure. The pressure here is the hydrostatic pressure of the blood. An easy way to think of that is the amount of fluid that is in your vessels. If you put more fluid in and it can't leave, you will have higher diastolic pressure. Example of elevated diastolic pressure can occur in patients if they have extra solutes in their blood (more fluid will be drawn into the blood).
Systolic pressure is the higher number and consists of the pressure in the system due to the heart beating. An example of elevated systolic pressure occurs in patients whose arteries are no longer or less elastic. If you think about the heart closing (losing volume), the rest of the system can compensate by transiently expanding, which also helps to push blood along.
How they are measured is: systolic: the pressure the cuff at which the blood flowing through the brachial artery can just barely push the artery open during left ventricle contraction - this means that the cuff pressure is approximately equal to the pressure blood in the brachial artery. Diastolic: the measure at which the cuff can no longer cut off blood supply because the cuff's pressure is roughly equal to the pressure the blood is exerting upon the walls of the artery.

aziz - it records the lateral pressure exerted by the flowing blood over the vessel wall .
