How to Diagnose an Airway Obstruction
Some diagnostic tests can help identify the cause of an airway obstruction. An X-ray may be performed in an emergency. If the results do not help, your doctor may suggest a bronchoscopy, which involves the use of a bronchoscope to look for signs of foreign objects in your lungs. This procedure may also help find out the presence of infectious causes. Another option to diagnose the condition is a laryngoscopy, which examine to larynx for symptoms of an airway problem. A CT scan of the chest, neck, or head may help with the diagnosis as well. [6]
