Recently, there has been a great deal of interest in high-frequency jet ventilation for thoracic surgery. According to previous studies, HFJV was delivered by an open system using a small tube. However, open system procedures run the risk of spreading blood and infected debris to the dependent lung. Therefore, we applied high frequency jet ventilation (HFJV) to the nonventilated, nondependent lung during one-lung ventilation using a double-lumen tube. We also investigated various other techniques such as increasing tidal volume, increasing the inspired oxygen concentration and insufflating continous oxygen with positive end-expiratory pressure (PEEP) in the nondependent lung. HFJV significantly improved arterial oxygenation, compared when the nondependent lung was opened to atmosphric pressure. Insufflation with oxygen at PEEP to the nondependent lung and ligation of the pulmonary artery as early as possible in the nondependent lung were also useful for improving arterial oxygeation during one-lung ventilation.
