[Mechanical ventilation in the acute lung injury/acute respiratory distress syndrome].

BACKGROUND AND OBJECTIVES: 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. Acute Respiratory Distress Syndrome (ARDS) has been one of the updated topics. This objective was described the most important topics related to mechanical ventilation in patients with acute respiratory distress syndrome.

METHODS: Systematic review of the published literature and gradation of the studies in levels of evidence, using the key words mechanical ventilation and acute respiratory distress syndrome.

RESULTS: Recommendations on the use of lung protective strategies during mechanical ventilation based on reduced tidal volumes and limitation of plateau pressure. The state of the art of recruitment maneuvers and PEEP titration is also discussed.

CONCLUSIONS: The mechanical ventilation of patients with ADRS changed in the last few years. We presented the role of lung protective strategies that could be applied to these patients.
