ABSTRACT

Objective: To evaluate lung mechanics, pulmonary physiology, retirement benefits of mechanical ventilation, length of ICU stay and mortality can have the use of APRV compared with conventional strategies of pressure-controlled ventilation with parameters neumoproteccion in patients with acute respiratory failure.
Methods: We conducted a clinical study, longitudinal, comparative and prospective patients admitted to 60 in the Intensive Care Units of the Secretaría de Salud del D.F. in the period of one year with a diagnosis of acute respiratory failure (PaO2/FiO2 < 300) and mechanical ventilation. Two groups, the group A is started conventional management strategies neumoprotection and B with APRV.
Results: In a sample of 60 patients 30 were ventilated pressure controlled manner and the other 30 with APRV, finding significant improvement (p < 0.05) of the blood gases and lung mechanics in the APRV group. We found a mortality rate of 8.3% in the control group pressure and 0% in the control group for APRV, and a reduction in the duration of mechanical ventilation and ICU stay in the group ventilated by this mode.
Conclusions: APRV should not be considered only as a non conventional mechanical ventilation applied for rescue in patients who have already established severe lung injury, but as a way ventilatory mode of first choice for patients with respiratory failure state critical, seeking to improve oxygenation, promote lung recruitment promote spontaneous respiratory activity and prevent further lung injury.
