Abstract
The COVID-19 pandemic has led to an increase in the demand for mechanical pulmonary ventilators (MPV), causing a great challenge for health managers, both in providing this equipment to patients in sufficient quantity, and in keeping them working properly. Like all equipment, MVs are composed of systems and subsystems. In order to guarantee the availability and proper performance of this equipment in a hospital environment, it is necessary to ensure the perfect functioning of the entire set of systems. This article aims to identify the main failure modes and their effects in MVs, and to propose actions for the most critical ones using the Failure Mode and Effects Analysis (FMEA) method. To this end, the INSPIRE MV developed by the Polytechnic School of the São Paulo University (USP), as part of the efforts to combat the COVID-19 pandemic, was taken as a basis. The nature of this study is applied and qualitative. A literature review was made about the main parameters of a MV, its classification, modeling and main critical components that can cause failure modes in the equipment, highlighting the MV INSPIRE equipment. The identification of the main failure modes was made based on data collected from the literature. Such failure modes have been validated by experts in the field. Also, to prioritize the failure modes, expert judgment was used. Based on the Risk Prioritization Number (RPR), actions were established to mitigate the main failure modes. Based on the results obtained, it is intended to generate knowledge regarding the operation of open source MVs, such as INSPIRE, in order to increase their availability and reliability.
