Because Vasc-Alert uses pressure instead of flow to determine accesses that have a problem, it can detect the growth of stenosis earlier than technologies that rely on the measurement of flow. Flow typically does not begin to degrade until the access is in the 70% to 80% closed range, whereas Vasc-Alert flags patients as being at risk in the 50% to 60% occlusion range. Given that the common belief is that early detection and intervention helps to extend the life of the access, it is better to identify patients earlier than later.

The most important reason to use Vasc-Alert is that it does not require any staff involvement with administering the test itself. The treatment run data needed for the algorithm is either copied to a computer automatically or already recorded on treatment run sheets. This frees up staff time to focus more on patient care issues such as managing the intervention process when a patient has been identified as having a problem with their access.

Vasc-Alert looks at the run time data coming from each treatment, not just monthly or quarterly. This provides better coverage and helps detect trends in the access before they become a problem.
