title: [Mechanical ventilation of weaning interruption].
abstract: OBJECTIVE
  The II Brazilian Consensus Conference on Mechanical Ventilation was published in 2000. Knowledge on the field of mechanical ventilation evolved rapidly since then, with the publication of numerous clinical studies with potential impact on the ventilatory management of critically ill patients. Moreover, the evolving concept of evidence - based medicine determined the grading of clinical recommendations according to the methodological value of the studies on which they are based. This explicit approach has broadened the understanding and adoption of clinical recommendations. For these reasons, AMIB - Associação de Medicina Intensiva Brasileira and SBPT - Sociedade Brasileira de Pneumologia e Tisiologia - decided to update the recommendations of the II Brazilian Consensus. Weaning from mechanical ventilation has been one of the updated topics. This objective was described the most important topics related to weaning from mechanical ventilation.
  
  
  METHODS
  Systematic review of the published literature and gradation of the studies in levels of evidence, using the keywords weaning and mechanical ventilation.
  
  
  RESULTS
  Recommendations on the weaning from mechanical ventilation and how to select patients applying weaning protocols and spontaneous breathing test.
  
  
  CONCLUSIONS
  Weaning is a very important period of mechanical ventilatory support. Weaning protocols are recommended to select patients ready to be extubated.
