The preservation of patent, well-functioning Arterial Venous Fistulas (AVF) is one of the most difficult clinical problems in long-term treatment of patients undergoing dialysis. 1  There are numerous complications associated with AVFs, and also Arterial Venous Grafts (AVGs), that regular surveillance can diagnose early enough to avoid emergency intervention which can put the patient at risk and can be costly for the unit. Other methods for dialysis access such as catheters also present potential complications which can result in emergency intervention being required.

Commonly surveillance is carried out on dialysis patients using Doppler Ultrasound or other methods but what if there was a simpler, efficient and more cost-effective way of monitoring dialysis access to avoid emergency intervention for complications such as stenosis and thrombosis?

Monitoring Vascular Access Flow 

Transonic’s ultrasound dilution technology is recognised as the “gold standard” in intra-access flow measurement technology and is the preferred method for AVG and AVF surveillance.3

With the Transonic HD03 you can directly measure access flow through a patient’s AVF or AVG for an instant snapshot of access function and identify ESRD patients at risk of underdialysis, thrombotic events and cardiac failure.

Monitoring Dialysis Adequacy

With a single infusion of saline, the Transonic HD03 identifies access recirculation, even at 0%. Optimise dialysis delivery and assess measurement of delivered pump blood flow and recirculation, identifying flow-limiting issues with your patient’s AVF, AVG or catheter.

Monitoring Cardiac Output

“Integration of cardiac output measurements into an ESRD treatment program forestalls the devastating progression of cardiovascular disease.” 4

With Transonic’s technology you can quickly and easily identify dangerously high levels of access flow in your AVFs and AVGs which can contribute to cardiomegaly and heart failure, and low cardiac output which places the patient at risk of developing cardiovascular complications.
