ABSTRACT

Positive pressure ventilation through a mask is one of the greatest advances in the management of acute respiratory failure. It is recommended as first-line management for ventilatory support in patients with exacerbations of COPD or cardiogenic pulmonary edema. Despite this, the use of noninvasive ventilation has not been universally accepted. There have been numerous studies which have shown that its use is fully described in hypercapnic respiratory failure but not in hypoxemic, also showed that factors associated with failure such as SAPS II, ECG and PaO₂/FiO₂ ratio.
Objective: To assess whether there are risk factors associated with group 2 corresponds to the patients upon admission were managed with of noninvasive ventilation failure.
Material and methods: A total of 122 patients were divided in two groups: group 1 patients on admission to the ICU were managed with mechanical ventilation, were extubated and had failure requiring group 2 corresponds to the patients upon admission were managed with of noninvasive ventilation, group 2 corresponds to the patients upon admission were managed with of noninvasive ventilation. In group 2 yielded two subgroups 70% success group in which the use of group 2 corresponds to the patients upon admission were managed with of noninvasive ventilation was successful, and the group fails 30% of patients who required endotracheal intubation.
Results: We found respiratory rate (p ≤ 0.0001) and mixed respiratory failure (p = 0.004) as independent risk factors for failure and they derived an equation to predict the risk of failure in patients with acute respiratory failure treated with group 2 corresponds to the patients upon admission were managed with of noninvasive ventilation, with AUC = 0.794.
