METHOD AND DEVICE FOR DETERMINING THE FISTULA FLOW OF A FISTULA FOR DIALYSIS TREATMENT

摘要

The invention relates to a method and device for determining the fistula blood flow of a fistula for dialysis treatment with a dialysis liquid by means of a dialysis machine, wherein the fistula has an arterial fistula outlet and a venous fistula inlet, comprising the following steps: varying the volume flow in the dialysis machine until local recirculation occurs in der fistula; determining the value of the volume flow in the dialysis machine when local recirculation occurs in the fistula as a first value QDO, and calculating the fistula blood flow Qso of the fistula on the basis of the first value QDO.
