Role of interventional pulmonology in intensive care units: A scoping review

Table 1 Tools in hemoptysis

Feature	Flexible bronchoscopy	Rigid bronchoscopy
Invasiveness	Less invasive; performed via nose or mouth	More invasive; requires general anesthesia and operating room
Airway control	Limited	Excellent
Reach	Greater; can access smaller, more peripheral airways	Limited; may not reach distal airways as effectively
Working channel	Narrower	Wider
Suctioning capacity	Limited	Greater
Instrument size	Limited	Larger instruments can be used
Visualization	May be limited in larger airways	Better visualization due to larger instruments
Tamponade	Possible, but less effective	Easier to achieve direct compression
Versatility	Allows for biopsies, lavages, and some therapeutic interventions	Primarily used for airway control and managing massive hemoptysis
Sedation	Often done under conscious sedation	Requires general anesthesia
Recovery time	Faster	Longer due to general anesthesia
Complications	Lower risk	Higher risk, although rare
Patient tolerance	Generally, more comfortable	Less comfortable due to larger scope

This table provides a general comparison. The best choice of bronchoscopy depends on the specific clinical situation and the expertise of the bronchoscopist.
