Pulmonary Damage Associated to Mechanical Ventilation

Abstract

Without any doubt the phenomenon that had the greatest influence on the study of Ventilatory Support is the acknowledgment of it carried out in the traditional way that since the massive generalization in 1967 was being implemented, it was able to cause damage to the lungs; clinical and anatomopathologically indistinguishable to the one produced in the Respiratory Defficulty Syndrome in Adults, SDRA, associating it to an increase in mortality in a 26 percent. Since then, several studies has tried to explain the relationship between ventilatory support and the clinical syndrome, already established in the human being of associated damage to ventilatory support giving rise to several etiopathogenic hipothesis, one of which is presented and advocated in this paper. Besides we present several ventilatory parameters and choices intended to diminish the necessary concentration of oxigen in the inhaled air and reduce the damage related to ventilation. This framework is a proposal of controlling the ventilatory support in patients with SDRA that is being developed by the authors and is being submitted to discussion and analysis throughout the country.
