Method for detecting recirculation in an arteriovenous shunt during ongoing haemodialysis and dialysis system

摘要

The control method involves setting a desired blood flow value, at which the recirculation is adjusted and the parameter detected by a sensor (6) adopts an appropriate value. The blood flow value is changed to another lower blood flow value, where a new parameter value is appropriately provided and detected at the sensor. The recirculation is determined based on the course of change or the change from the former parameter value to the latter parameter value. An independent claim is included for a dialysis machine with pressure sensors.
