The development and testing of a prototype venous needle dislodgement detection device

Inadvertent venous needle dislodgement (VND), from graft or arterio-venular fistula, can lead to haemorrhage resulting in a serious life-threatening complication and in some cases death by exsanguination. This paper eloquently articulates the development and testing of a novel Arduino based VND detection device. The VND detector is subjected to four testing protocols to critically analyse the efficiency of VND detection within a 12-second window. Implementation of statistical analytic methods to the obtained results successfully demonstrated the VND detector's ability to detect VND within 12 seconds.
