Which is true about laryngeal spasm in drowning victims?

Laryngeal spasm, also known as laryngospasm, is a protective reflex that occurs in response to water entering the airway, particularly in drowning scenarios. This spasm temporarily closes the vocal cords, which effectively prevents water from entering the lungs. This reflex can cause a victim to take very shallow breaths or none at all, which can prolong the time before water enters the lungs, thereby possibly delaying pulmonary complications associated with drowning.

In the context of drowning victims, this mechanism is crucial as it can allow the individual to survive longer until rescue measures can be initiated. This protective response is essential because it highlights the body's reflexive attempt to safeguard vital organs and maintain airway integrity during drowning incidents.
