Primary Outcome Measures:
  • Lowest oxygen saturation during bronchoscopy, development of hypoxemia(SpO2<90%) during bronchoscopy [ Time Frame: during the fiberoptic bronchoscopy, estimated procedure time is about 15min ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Need for oxygen flow increment [ Time Frame: during the fiberoptic bronchoscopy, estimated procedure time is about 15min ] [ Designated as safety issue: No ]
  • the proportion of subjects who is require of mandible lift [ Time Frame: during the fiberoptic bronchoscopy, estimated procedure time is about 15min ] [ Designated as safety issue: No ]
  • time delay for procedure due to hypoxemia [ Time Frame: during the fiberoptic bronchoscopy, estimated procedure time is about 15min ] [ Designated as safety issue: Yes ]
  • the proportion of subjects with snoring [ Time Frame: during the fiberoptic bronchoscopy, estimated procedure time is about 15min ] [ Designated as safety issue: No ]

Detailed Description:

Currently, diverse sedatives and analgesic methods are used during fiberoptic bronchoscopy for reducing patients' discomfort and facilities of procedures as British Thoracic Society recommendation. MAC anesthesia, one of the widely used sedative method during bronchoscopy, have many advantages, occurrence of respiratory depression, hypoxemia are not uncommon during the procedures. The investigators try to find out risk factors and develop the prediction model for hypoxemia during bronchoscopy under MAC anesthesia.
