Results:

The presence of leaks, the start time of the treatment longer than 24 hours, the decrease in the average values ​​of pH and Glasgow, the increase in respiratory and heart rates and PaCO2, are associated with failure of non-invasive ventilation.

Conclusions:

Alterations of typical clinical and hemogasometric variables of ventilation, structure the failure in this patients population.
