ABSTRACT

High frequency oscillatory ventilation (HFOV) is a mode that has proven useful as a rescue therapy in patients with severe hypoxemia refractory to conventional mechanical ventilation (CMV), ARDS and air leaks. This case report depicts a patient, with acute respiratory failure who developed persistent hypercapnia refractory to CMV, in whom the early introduction of HFOV could prevent overdistension of the alveolar units and volutrauma, in addition to reverting the persistent hypercapnia by maintaining its sustained effects over time. Both HFOV and CMV can result in complications, air leaks being one of the most serious ones, increasing the length of hospital stay, the duration of mechanical ventilation and mortality rates. The patient presented with generalized subcutaneous emphysema, pneumomediastinum, right and left pneumothorax and pneumoperitoneum. HVOF ventilation strategies are reviewed given the air leak underlying pathophysiological condition.
