Usability Evaluation for a Vital Signs Monitor Prototype

Abstract

Abstract--The usability test performed as part of the processes of biomedical equipment development has great importance for safety use of health care technology, between 50% and 70% of adverse events with medical devices are related with assembly mistakes, wrong connections and incorrect operation. Usability test requires detailed processes with rigorous methodologies that guarantee test to the user, who measures several aspects of the use, interface and process in the equipment. This article compares the usability of a prototype of vital signs monitor against a commercial product in terms of some aspects of the human factor engineering that were applied in order to test the usability of a Prototype, the commercial vital signs monitor is used as a reference. This paper integrates a methodology composed by 3 phases that allows an analysis of users` behavior interacting with medical devices. Time and steps were analyzed through statistics and heuristic analysis.
