title: Does resistance of the saline column in pressure monitoring catheters change as a function of applied voltage?
abstract: It had been suggested that the electrical impedance of a fluid-filled pressure monitoring catheter might be a function of applied 60 Hertz voltage. If so, the possibility of patient shock hazard might be increased.  A variety of catheters were tested with several physiological solutions over a wide range of applied 60 Hertz voltages. No evidence was found to indicate that the resistance of fluid-filled catheters is a function of applied voltage.
