“A hemodynamically significant stenosis is the substrate for thrombosis by reducing flow, increasing turbulence, and increasing platelet activation and residence time against the vessel wall.” KDOQI Guidelines 2006³ 

Transonic Hemodialysis surveillance provides the nephrologist with myriad information that helps formulate an ideal treatment plan tailored for each patient. Listed below are eight ways that Transonic flow surveillance informs a nephrologist.

1. Tells quantitatively actual function in AV grafts and fistulas in order to identify failing accesses and avert underdialysis, development of stenosis and/or thrombosis
2. Indicates effectiveness of interventions (post-intervention surveillance) or limb ischemia
3. Excludes access dysfunction quickly as cause of underdialysis
4. Identifies a mid-access obstruction
5. Identifies high-flow versus low-flow accesses to select ideal treatment plan for correction (flow-restricting versus re-vascularization procedure)
6. Permits access surveillance to be performed by the clinic’s staff who then can alert nephrologists to possible onset of access dysfunction & referral for early intervention
7. Implements 2006 KDOQI Guidelines³
8. Implements Best Practices for patient care with Gold Standard reference method.
