Diffuse alveolar disease, including hyaline membrane disease, acute respiratory distress syndrome, systemic inflammatory response syndrome, and pneumonia 3.undefined#ref3"> 3 Alveolar recruitment continues for several hours after HFOV therapy begins, and arterial partial pressure of carbon dioxide (Pa CO 2) values may initially climb. With HFOV, oxygenation and elimination of carbon dioxide occur as long as the lung is inflated. This decreased V T decreases barotrauma and allows for healing of the lung tissue. HFOV delivers a smaller tidal volume (V T) than conventional ventilation, usually less than or equal to the anatomic dead space volume. HFOV is the most commonly used mode of HFV. Modes are described by the delivery method and classified by the exhalation mechanism (active or passive). Several modes of high-frequency ventilation (HFV) are available. Potential complications of high-frequency oscillatory ventilation (HFOV) include hemodynamic compromise, barotrauma, inadequate humidification, endotracheal (ET) tube obstruction, and intraventricular hemorrhage in the neonate.Īsymmetric chest rise may indicate a pneumothorax.
