Failure Analysis of Vital Sign Monitoring System in Digital Healthcare with FTA

Abstract

Digital healthcare system requires safety critical software and more attention among human perception and assistance of computer. Apparently, it becomes serious challenge for engineers and doctors in assuring the secure and reliable healthcare system. The main target is patient safety here, thus important factor to consider in healthcare is system protection. In recent research vital signs such as heart rate (HR) and breathing rate (BR) are extracted using a non-invasive IR-UWB radar sensor. Hence, safety of the contactless device is necessary for proper and accurate measurement of HR and BR in digital healthcare system. Therefore, in our research we drawn and performed fault tree analysis (FTA) of such system which analyze potential hazards of measuring subject’s HR and BR in a non-contact fashion. We emphasize on crucial issues and safety factors which are important in patient safety and protection before the proper deployment of such healthcare system.
