Conditions

Sedation Method

Brief summary

To compare the difference of sedation monitoring for bronchoscopic examination monitoring by auditory evoked potentials (AEP) or Ramsay Sedation Scale (RSS) in mechanical ventilated patients.

Interventions

DEVICEAEP monitor

In AEP monitoring group, nurses adjusted propofol dose according to AAI values. If AAI\>40, titrate up propofol dosage, AAI\<25, titrated down propofol dosage.

During bronchoscopy, nurses adjusted propofol dose according to Ramsay Sedation Scale.
