[Comparison among three methods to measure the rapid shallow breathing index in patients submitted to weaning from mechanical ventilation].
To compare the attainment of the rapid shallow breathing index (IRRS) in modalities PSV 10 cmH2O and PEEP 5 cmH2O (PSV10), CPAP 5 cmH2O (CPAP5) and spontaneous breathing (SB), correlating them with success on failure in the withdrawal of mechanical ventilation (MV). ⋯ From this sample, it can be observed that IRRS values are overestimated when gotten in modality PSV10. It was also evidenced that there is no need of a 30 min T-tube SB before extubation, when the weaning is performed with the technique of gradual reduction of PSV. This study suggested that IRRS is able to predict weaning success; however it is not able to determine failure when it was < 105. It is recommended that IRRS must be analyzed in association with other predictive weaning parameters.

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

Intraoperative mechanical ventilation has been one of the updated topics. This objective was described the most important topics on the intraoperative mechanical ventilation. ⋯ Pulmonary atelectasis is a common complication observed in the postoperative period, thus ventilatory techniques has been adapted to prevent these complications.
