The use of high-frequency oscillatory ventilation in adult ARDS patients.
Current ventilatory objectives for adults with ARDS include maximizing gas exchange while minimizing lung injury. To this end, high-frequency oscillatory ventilation (HFOV), a mechanical ventilation strategy that simultaneously avoids end-inspiratory alveolar overdistension and end-expiratory alveolar collapse, has been recommended. HFOV meets these criteria from a theoretical perspective, however, is without the benefit of a prospective randomized clinical trial of CMV versus HFOV to demonstrate that effect. This article provides an overview of high-frequency oscillation, followed by an illustration of how it was applied in the case of a 43-year-old patient who developed respiratory failure 24 hours post-Caesarean section.
