Abstract

A system and method for identifying a disruption of a flow from an extracorporeal circuit to a patient circulatory system, such as a venous needle dislodgement or an access-bloodline separation, is based on flow rate data of the extracorporeal circuit. A patient contribution to the flow rate data can be identified as a harmonic and monitored to assess the presence of the disruption. The system can identify an inharmonic change, such as a spike, in the flow rate in the extracorporeal circuit, wherein the inharmonic change can be used alone or in conjunction with the identified harmonic to assess the existence of the disruption. The system can employ the spike in a blood flow rate as well as a spike in a dialysate flow rate fluidly connected to the extracorporeal circuit, wherein the spike can be used to identify the disruption.
