Revisão dos parâmetros de sucesso da ventilação não invasiva na insuficiência respiratória aguda

Abstract

This work is about a bibliographical revision of the studies published between the years of 1990 and 2002, on the parameters of success of the not invasive ventilation with positive pressure in the acute respiratory insufficience. It has as objective main, to relate and to argue such parameters and thus to search a more efficient and less traumatic boarding for these individuals. Despite not the existence of a referring consensus to the success parameters, they have demonstrated that the clinical improvements (FR, degree of dispnéia, use of accessory respiratory musculatura) and gasométricas are of great value in a good prognostic for this therapy. They still place that such parameters must be considered by presenting alterations, for better or worse, with little time of NPPV application, thus occurring they do not have to be taken measured invasive, or either intubação. Another important factor demonstrated by some authors is that patient more serious they have minor success possibility and still that props up it high Apache II becomes related with the imperfection of the NPPV. The taxes of success as for application of the NPPV have if demonstrated sufficiently changeable, they are placed that such discrepancies if must the variations in the criteria of inclusion and exclusion adopted to the patients, to the applied way of ventilation, as well as instituted the different levels of positive pressure and still to the levels of it props up Apache II of the individuals used for the study. The NPPV if has shown each more efficient time in the treatment of the ARF and the agudizada chronic respiratory insufficience, thus improving the quality of life and diminishing the indices of traqueal intubação, its complications.
