Catheter Adequacy in Hemodialysis & Transit Time Flow Measurement

New Call-to-action

More than 75% of end-stage-renal disease (ESRD) patients have a central venous catheter either to initiate hemodialysis or for permanent hemodialysis delivery, even though it is well known that central venous catheters are prone to thrombosis and infection. KDOQI Guidelines recommend blood flow in catheters be maintained at more than 300 mL/min to ensure adequate hemodialysis and avoid life-threatening catheter dysfunction. Yet, central venous catheters often underdeliver dialysis due to a discrepancy between a pump’s setting and its actual delivered flow and/or the presence of recirculation.

Transonic® Hemodialysis Monitors are the only technology that can measure both delivered blood flow and the amount of recirculation to optimize dialysis delivery by: 

  1. Establishing a maximum dialysis pump setting before recirculation occurs; 
  2. Using known values for flow and recirculation to adjust the length of dialysis;
  3. Identifying flow restrictions and finding the best connections between a catheter and blood lines.

Best Practice: Ensure adequate dose delivery per KDOQI Guidelines by direct measurement of delivered blood flow and recirculation in catheters with Transonic flow surveillance.
