Brief resolved unexplained event - BRUE

Apparent life-threatening event; ALTE

A brief resolved unexplained event (BRUE) is when an infant younger than one year stops breathing, has a change in muscle tone, turns pale or blue in color, or is unresponsive. The event occurs suddenly, lasts less than 30 to 60 seconds, and is frightening to the person caring for the infant.

BRUE is present only when there is no explanation for the event after a thorough history and exam. An older name used for these types of events is an apparent life-threatening event (ALTE).
