A pressure isolation mechanism including a valve housing which defines a first lumen associated with a pressurizing device, a second lumen associated with an input line which connects a low pressure fluid delivery system to the valve housing, and a pressure isolation port is disclosed. The pressure isolation mechanism further includes a first valve having a normally open position permitting fluid communication between the first lumen and the second lumen and movable to a closed position when fluid pressure in the first lumen reaches a predetermined pressure level, and a second valve disposed within the second lumen and regulating fluid flow through the second lumen, wherein the second valve substantially isolates the input line from a pressure transducer connected to the pressure isolation port. A method for correcting for dampened hemodynamic blood pressure signals in a fluid delivery system which includes the pressure isolation mechanism is also described.
