Effective dialysis depends on delivery of the dialysis prescription through functional blood lines into a patent vascular access. Underdialysis is often caused by poor delivered blood flow. Transonic® Hemodialysis Monitors measure true delivered blood flow through dialysis tubing to assure delivery of the prescribed dialysis prescription. By comparing the actual delivered blood flow reading of Transonic through the dialysis lines connected to a graft, fistula or catheter with the setting on the dialysis pump, dialysis delivery problems can be quickly identified and resolved.
Delivered blood flow is used to:
- Test blood pump calibration and its “effective flow” algorithm;
- Determine the cause of excessive negative arterial pressure;
- Determine the most appropriate blood pump setting for a low flow access when it is not feasible to increase access flow;
- Diagnose tubing set flow restrictions, a cause of hemolysis.
Best Practice: Ensure adequate dose delivery by direct accurate measurement of pump blood flow in AV accesses and catheters with Transonic flow surveillance.
