Análise de indicadores de manutenção dos umidificadores aquecidos do Hospital de Clínicas de Uberlândia da Universidade Federal de Uberlândia

Abstract

This study is exploratory in nature and has as its final objective to be able to suggest hypotheses of improvement on the maintenance plan of the heated humidifiers of Hospital de Clínicas de Uberlândia. The heated humidifier is an equipment that helps patients dependent on invasive mechanical ventilation to be more comfortable during use, since the gases that leave the hospital gas network are cold and dry and this EMA (Medical Assistance Equipment) has the function of heating and humidify the air in order not to harm the patient's airway. Thus, data were collected from the SisBiE (Bioengineering System) of the humidifiers during the period from January 2014 to April 2018. The calculations were performed on the maintenance indicators Mean Time Between Failures (TMEF), Mean Time of Repair (TMR) and Availability (DISP). The indicators were calculated as suggested by the literature and the equations used in Bioengineering and the analysis was done by means of graphs and tables, comparing discrepant values ​​obtained. This study reached its initial goal and concluded that humidifiers are low-complexity, easy-to-maintain equipment that is of utmost importance to the hospital and has a very high availability of use and has few corrective maintenance over its lifetime. In addition, it was observed that for a better understanding of the whys of its correctives it needs a more in-depth study together with the engineering team of Hospital de Clínicas de Uberlândia.
