Dr. Robert Bastian of Bastian Voice Institute explains laryngospasm with video of the larynx and a simulated attack.
Laryngospasm is a sudden, often severe attack of difficulty breathing, typically lasting between 30 and 90 seconds. Usually the individual makes a frightening noise while trying to breathe in during the episode, which they often call a “choking attack. You will hear the types of noises often made by the person experiencing laryngospasm, and see what the vocal cords are doing at the same time.
