Análise dos indicadores de manutenção dos equipamentos de osmose reversa portátil do Hospital de Clínicas de Uberlândia da Universidade Federal de Uberlândia

Abstract

This paper presents an analysis of portable reverse osmosis indicators of the University Hospital of Uberlândia of the Federal University of Uberlândia, which aims to assess the maintenance, reliability, and availability of equipment with the use of performance indicators, time to repair (TTR), mean time between failures (MTBF), and availability. The calculated indicators are based on the Bioengineering sector of HCU-UFU and the common ones used in the literature. The indicators are used by managers to help maintain the applications, with lower maintenance costs, avoiding that the equipment spends a lot of time stopped during the failures, helping in the performance of the team and others. The data were obtained through the HCU-UFU technology park management software, SisBiE, from the Bioengineering sector of HCU-UFU. The data analysis period was from January 2014 to April 2018 included a total of 12 portable reversal units, totaling 386 maintenance units for correction, in which they were used for the measurement of the indicators, TTR, MTBF, and Availability. The four different brands of reverse osmosis sign from A to D to preserve an image of the marks. After comparing the models of performance indicators for PSM models and indicators, TTR, MTBF, and Availability by model. Next, comparisons between brands and indexes of indicators were made. When performing the analysis of the comparison between the brands it is possible to observe that the equipment A was the one that presented the most amount of bad indicators, appearing in the graphs between one of the brands with the highest number of PSMs, lower MTBF and lower Availability. Other issues that deserve attention, for example, are in relation to the quantity of PSMs of the D mark, as well as the high TTR for the C mark.
