    AbstractAn experimental study on dogs was performed to determine the optimal driving gas pressure and frequency in high-frequency jet ventilation (HFJV) during tracheobronchoplasty. Right thoracotomy, sleeve upper lobectomy and sleeve pneumonectomy were done with various HFJV settings and insufflation via a 3.0 mm catheter with 2.4 mm internal diameter. In sleeve lobectomy, HFJV to the reconstructed lung improved the peroperative ventilation. Driving gas pressure 0.5-1.0 kg/cm2 and frequency 6-10 Hz were the optimal settings for sleeve lobectomy. In sleeve pneumonectomy adequate ventilation and oxygenation were achieved with HFJV to the contralateral lung, and the optimal HFJV settings were 1.0-2.0 kg/cm2 driving gas pressure and 6-10 Hz frequency.
