Abstract:
We report the successful application of high-frequency oscillatory ventilation in a patient with tension pneumatocele (TP). The proposed check-valve mechanism for the development of pneumatoceles predicts that positive-pressure ventilation could lead to distension of these airspaces and formation of TPs. Therefore, high-frequency ventilation could be more applicable in conditions, such as massive air leak due to bronchopleural fistula, that are difficult to manage by conventional ventilator modes.
