We report the successful weaning and extubation of an infant from a SensorMedics 3100A high-frequency oscillator without returning to conventional ventilation. A 7-week-old term infant with respiratory syncytial virus bronchiolitis complicated by cystic pulmonary lesions repeatedly failed attempts to return to conventional ventilation from high-frequency oscillatory ventilation (HFOV) for weaning, because of recurrent pneumothoraces. A computed tomography of the chest revealed multiple well defined cysts of various sizes involving both lungs. Therefore, weaning to extubation from HFOV was proposed as a way of preventing further air leak. The weaning strategy consisted of a technique we refer to as "sprinting." Using this method, the patient was successfully extubated directly from HFOV, with no complications. A follow-up computed tomography of the chest showed marked improvement in the size of the cystic lesions. The patient was discharged home with no need for home oxygen therapy.
