Dialysis access flow volume measurement
WebSpectral Doppler signal between the dialysis needles at a dialysis blood pump rate of 400 ml/min in a patient with an access flow of 240 ml/min. The reverse flow seen in this patient is so extreme that access flow is nearly entirely reversed throughout the cardiac cycle at a dialysis blood pump rate of 400 ml/min. Discussion WebUltrasound evaluation has been shown to be helpful in determining clinical maturation of the DVA while looking at diameter, depth, and flow volumes at 2 and 6 weeks after a newly created access. , , A DVA is considered usable if the body of the access has a diameter of 4-6 mm and a depth of less than 5-6 mm, and the access has a flow volume of …
