A method of alerting a user to a potential unintended bolus delivery includes delivering fluid to a patient along a first fluid flow path (120). The method also includes transmitting a signal prior to initiation of a change in fluid delivery to the patient along a second fluid flow path (190) connected to the first fluid flow path upstream of the patient, and detecting the signal. The method further includes acutating an alarm to alert the user to a potential unintended bolus delivery if the signal is detected. A system (100) for carrying out the method is also provided.
