Resumo
The  study  was  motivated  by  the  critical  importance  of  sterilization  performed  by autoclaves  for  the  proper  and  safe  treatment  of  patients  in  hospital  environments.  It aimed  to  improve  the  maintenance  plan  for  a  Baumer  HI  VAC  MX  II  B0112  autoclave used  for  sterilization  in  a  hospital  setting,  classified  as  a  Category  V  pressure  vessel under  NR  13.  The  methodology  included  an  analysis  of  the  maintenance  history (2022–2023), identification  of  critical  components,  implementation  of  predictive maintenance  techniques  (non-destructive  testing  and  visual  inspection),  optimization of  the  maintenance  schedule,  improvement  in  inventory  management,  and  the implementation  of  a  data  recording  and  analysis  system.  The  results  showed  an increase  in  maintenance  performance  indicators,  with  a  23.4%  improvement  in  MTBF (Mean  Time  Between  Failures),  rising  from  255.5  to  315.22  hours.  Additionally,  there was  a  29%  reduction  in  MTTR  (Mean  Time  to  Repair),  decreasing  from  18.65  to 13.25  hours,  and  an  increase  in  equipment  availability  from  92.37%  to  95.97%. Improvements  included  predictive  maintenance,  schedule  optimization  based  on actual  wear,  integrated  inventory  management,  and  compliance  with  regulations  such as  RDC  15.  Despite  the  short  post-improvement  analysis  period  (6  months),  the project  demonstrated  potential  to  enhance  operational  efficiency,  reduce  costs,  and improve  safety.  Continuous  monitoring,  full  implementation  of  the  proposed  actions, and  expansion  of  the  predictive  maintenance  plan  are  recommended.  The  project contributed  to  the  optimization  of  sterilization  processes,  positively  impacting  the quality of patient care and the safety of medical procedures.
