Mechanical ventilation is considered a basic element of life support in the intensive care unit and is essential for patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Experimental studies have demonstrated that mechanical ventilation with high volumes and/or high pressures can exacerbate (VALI) or induce lung injury (VILI) with histological aspect similar to ALI/ARDS. ⋯ It is fundamental to understand the mechanisms related to volutrauma, atelectrauma, and biotrauma to avoid ventilator-associated lung injury.

[A comparative study between early and late tracheostomy in patients ongoing mechanical ventilation].
To assess the incidence of tracheostomy in patients submitted to mechanic ventilation (MV); to compare the length of stay (LOS), duration of MV, APACHE II and mortality among patients submitted to tracheostomy, according to the moment of its application (early or late). ⋯ The incidence of tracheostomy was high, being associated to a smaller ICU mortality but with a longer LOS and more complications. There was no significant difference regarding the destination of the patients when submitted to early or late tracheostomy.
