Abstract

A method of alerting medical personnel of a problem during hemodialysis includes providing an active, fail-to-se site sensor (180) for a fistula needle (150) at an access site during hemodialysis; and automatically alerting medical personnel of a problem during hemodialysis using the active, fail-to-safe site sensor during at least the following: failing of the active, fail-to-safe site sensor; insufficient powering to the active, fail-to-safe site sensor; partial fistula needle dislodging from the access site; and complete needle dislodging from the access site.
