According to research published in the online journal The Laryngoscope, exercise-induced laryngeal obstruction (EILO) can be effectively diagnosed using a flexible laryngoscope.

Exercise-induced obstruction of the larynx is often a cause of respiratory symptoms in athletes and is particularly prevalent in swimmers. A new report reveals a method to accurately diagnose this condition, using a flexible laryngoscope.

Confirming a diagnosis of exercise-induced laryngeal obstruction (EILO) requires visualizing movement of the larynx during intense exercise. In this latest report, investigators used waterproof tape to secure a laryngoscope to the nose, along with a modified swim cap and a laryngoscope cable that was suspended above the water and connected to a monitor.
