Abstract: A first venous rhythm of a patient is detected above a venous insertion site when a venous catheter connected to an infusion set is inserted into the venous insertion site and, concurrently with the first venous rhythm, a second venous rhythm is detected at a location remote from the venous insertion site. An irregularity between the first and second venous rhythms is identified, and a failure of the venous catheter is determined based on the identified irregularity satisfying a irregularity threshold. An alarm may be provided on detecting the irregularity or the failure of the venous catheter.
