A system is provided for detecting the presence of an infiltration condition in a line delivering fluid to a patient. Stepping means subjects the fluid in the line to a negative pressure step. The pressure of the fluid is monitored, and processing means then determines whether an infiltration condition is present by determining whether the function of line pressure over time in response to the occurrence of a negative pressure step exhibits a relative slow return to the pre-step pressure, such relatively slow return being characteristic of the presence of infiltration.
