White Paper: Standard Issues Relating to the Detection of Venous Needle Dislodgement

This document deals with how the risk of venous needle dislodgement is treated under US and European Medical Standards. In both sets of standards, it is acknowledged that venous needle dislodgement can cause potentially lethal situations and that there is currently no optimal system available for detection.

Various organisations and other sources confirm the lack of an optimal alarm, adding proof of incidents where an adequate alarm could have changed the fatal course of events. Redsense is the first clinically tested monitoring system for venous needle dislodgement in hemodialysis.
