The purpose of this article was to introduce an easy and inexpensive way of making a simulator for training in Doppler ultrasound flow rate measurement using a continuous renal replacement therapy machine and home-made phantoms. A Doppler ultrasound flow simulator was made using a continuous renal replacement therapy machine and vascular phantoms for flow rate assessment of dialysis access with readily accessible components including rubber tube, keyboard cleaning gel, and freeze-dried instant coffee granules. The simulator is an affordable and easy method of Doppler ultrasound flow rate measurement training for dialysis staff using materials readily available in dialysis centers.
