Q: Following is the usual layout of an arterial line setup. How much fluid is usually push through the pressure bag line towards transducer to keep it open?


Answer:

The pressure bag is a way of keeping the right amount of fluid flowing thru the A-line. It pushes HARD against the transducer and the transducer allows 3cc/hr of Normal Saline thru the transducer into the A-Line. This is like a TKO IV Fluid for the A-Line. Also,  pressure bag's pushing against the transducer keeps the wire getting the right signal.
