Background: There have been numerous advancements in airway equipment since the flexible fiberoptic bronchoscope was initially used. Clinicians must be aware of the functions and constraints of the equipment that is currently on the market in order to make the best decisions. Poor judgment combined with the wrong equipment selection was revealed to be a contributing factor in airway morbidity and mortality in the United Kingdom's Fourth National Audit Project. For the evaluation, diagnosis, and treatment of patients with respiratory diseases, flexible bronchoscopy (FB) is a common and safe procedure. Since Facebook was first created in 1967, its process and applications have gradually changed and grown. The fiberoptic intubation technique involves passing a tracheal tube loaded along its length through the glottis to enable for a flexible oral or nasal route that clearly visualizes the vocal cords. The endoscope is then removed once the tracheal tube has been inserted into the trachea. Conclusions: Awake fiberoptic intubation is widely advocated for the management of the known or anticipated difficult airway. However, fiberoptic intubation can be a challenging technique to learn, and continuous practice is needed to maintain the skill.
