When is intubation indicated for stridor?

Intubation is indicated for stridor in situations where there is significant airway compromise, such as severe swelling or epiglottitis. In cases of severe swelling, the airway can become dangerously obstructed, and immediate intervention is required to secure the airway and ensure proper oxygenation. Epiglottitis, which is inflammation of the epiglottis often due to infection, can lead to rapid deterioration and complete airway occlusion, making intubation a critical step in management to prevent respiratory failure.

In contrast, anxiety-related symptoms may present with stridor due to hyperventilation or muscle tension but generally do not require intubation unless there are underlying respiratory issues. Mild airway obstruction typically does not necessitate intubation as there may be alternative management options available, such as steroids or nebulized treatments. As for a heart attack, it is unrelated to stridor and would not be an appropriate indication for intubation in that context.
