Exercise-induced obstruction of the larynx is often a cause of respiratory symptoms in athletes and is particularly prevalent in swimmers.

‘A method to accurately diagnose exercise-induced laryngeal obstruction (EILO), using a flexible laryngoscope, has been developed by researchers.’

Confirming a diagnosis of 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.




The recorded laryngoscopic video provided stable, high-quality diagnostic images of the larynx during exercise, without disrupting swim strokes or breathing.
"This is a major step forward to help us accurately diagnose breathing problems in swimmers. EILO is a very common cause of breathing problems during swimming and is so often misdiagnosed and mistreated as asthma," said Dr. James Hull, senior author of The Laryngoscope article.
