Purpose: Automatic non-invasive measurement of the force exerted by circulating blood on the walls of arteries. Adequate blood pressure is essential to maintain the blood supply and function of vital organs. Measurement of blood pressure is therefore a key part of the monitoring of patients during anaesthesia and critical care.
How Works: A single cuff is applied to the patients leg, and the machine inflates it to a level assumed to be greater than systolic pressure (i.e. peak arterial pressure when the ventricles contract). The cuff is deflated gradually. A sensor then measures the tiny oscillations in the pressure of the cuff caused by the pulse.; Systolic is taken to be when the pulsations start, mean pressure (i.e. average arterial pressure throughout cardiac cycle) is when they are maximal, and diastolic (i.e. lowest arterial pressure during resting phase) is when they disappear.
A common test in a chemistry panel that measures the amount of nitrogen in the blood that comes from the waste product urea. It can be used to see how well the kidneys and liver are working and if dehydration is present.

A specialized system of capillary endothelial cells as well as certain processes from astrocytes that strictly limits transport into the brain through both physical (tight junctions) and metabolic (enzymes) barriers. Certain microscopic objects (e.g. bacteria, toxins, etc.) are restricted while others essential for brain function (e.g. oxygen, glucose) are allowed to pass.
