Are you as anesthesiesed during a bronchoscopy like you are for a endoscopy?

Yes. Yes, in general the level of sedation is similar for most routine flexible bronchoscopies. A deeper level of sedation may be required for rigid bronchoscopy or more complex procedures.
Yes. During bronchoscopy you receive conscious sedation. You aren't out completely but are comfortable for the procedure similar to colonoscopy or upper GI endoscopy.
Depends. Some places will put you completely to sleep, others will just use conscious sedation.
