Block diagram <strong>of</strong> the major components and subsystems <strong>of</strong> an oscillometric blood-pressure<br />
monitoring device, based on the Dinamap unit, I/O = input/output; MAP = mean arterial<br />
pressure; HR = heart rate; SYS= systolic pressure; DYS = diastolic pressure. From Ramsey M III.
