Swift recovery of severe acute hypoxemic respiratory failure under non-invasive ventilation.

BACKGROUND

In the setting of severe acute respiratory distress syndrome (ARDS; PaO2/FiO2 < 100), the cut-off point for switching from non-invasive ventilation to intubation combined to mechanical ventilation is poorly defined.

RESULTS

The swift resolution over 10 h of a severe acute hypoxemic respiratory failure (P/F = 57) caused by aspiration following heroin overdose, using non-invasive ventilation (NIV)-high PEEP (15-20 cm H2O)-low pressure support (8 cm H20) is reported. The success in treating non-invasively severe hypoxia was presumably linked to a highly restricted subset: healthy young patient, minimal alteration of consciousness, non-combativeness, absence of severe metabolic acidosis, quick resolution of supraventricular arrhythmia, one-to-one supervision by the intensivist in the critical care unit.

CONCLUSION

Given the complications associated with tracheal intubation and mechanical ventilation on the one hand and with delayed intubation on the other hand, high PEEP-NIV may warrant study in a restricted set of patients closely monitored in a critical care environment.
