The infusion system is provided for examining a waveform for a pressure artifact characteristic by patient activity which gives serious influence on alarm reliability. When the system detects the occurrence of an artifact which exceeds a predefined level of departure from a nominal system operation, the system recognizes it as a patient-induced and sufficient cause to prolong, ignor or rerum a site check.
