In medicine laryngospasm is an uncontrolled/involuntary muscular contraction (spasm) of the laryngeal cords. The condition typically lasts less than 60 seconds and causes a partial blocking of breathing in while breathing out remains easier. It may be triggered when the vocal cords or the area of the trachea below the cords detects the entry of water mucus blood or other substance. It is characterized by stridor and/or retractions.
