“Intraoperative measurements of access blood flow provide objective, reliable data that correlate to outcome. Routine use of this technology might lead to more efficient management of patients undergoing hemodialysis access surgery.”
Johnson CP et al, Surgery 1998; 124: 729-38.

Whether creating a new access or revising an existing one, flow measurement provides on-the-spot, quantitative feedback about the quality of the access flow. Intraoperative blood flow measurements during vascular access creation are indicative of future access patency. Transonic® flow measurement allows the surgeon to identify the presence of hidden flow obstructions and confirm the success of the procedure before closure. Measurement during flow restoration or reduction procedures confirms that the target flow rate has been achieved, reducing the need for follow-up procedures.
