Apparatus and related method for use in a parenteral administration system, for detecting fault conditions such as an infiltration, an open fluid line or an air bubble in the fluid line. The apparatus is particularly adapted for use with a parenteral administration system of the type that includes a pulsing infusion device for incrementally infusing fluid through a fluid tube to a patient\s venous or arterial system. The apparatus qualitatively evaluates the pressure in the fluid tube to detect characteristic patterns indicative of each such fault condition and actuates an alarm whenever one is detected.

Fault detection apparatus for use with a parenteral administration system having an infusion device for infusing parenteral fluid through a fluid tube to the vascular system of a patient, comprising: pressure transducer means for monitoring the pressure of the fluid in the fluid tube and producing a corresponding pressure signal; fault detection means for evaluating the pressure signal over a period of time to detect characteristic patterns in the waveform of the pressure signal evaluated which are indicative of improper fluid communication between the fluid tube and the vascular system of the patient; and means for producing a corresponding alarm signal whenever the fault detection means detects such a characteristic pattern.
