A Case of Tension Pneumothorax during High Frequency Left Jet Ventilation in Laryngomicrosurgery / 대한마취과학회지

We experienced a case of tension pneumothorax during high frequency jet ventilation. The possible cause of barotrauma in this case was obstruction of gas escape. It is recommened that meticulous care is taken to ensure and adequate pathway for expiration when HFJV is used.
