The first, ALTE is defined as a collection of symptoms that is frightening to the observer which may include color change, apnea, change in muscle tone, and/or choking or gagging. The second, SIDS is a diagnosis rather than a collection of symptoms and is defined as a sudden unexpected infant death for which there is no explanation. In order to make the diagnosis of SIDS, there must be a complete autopsy, review of the medical and family history, and death scene investigation that excludes predisposing environmental factors and does not result in a clear explanation for the infant’s death. The third, infantile apnea is defined by the American Academy of Pediatrics (AAP) as “an unexplained episode of cessation of breathing for 20 seconds or longer, or a shorter respiratory pause associated with bradycardia, cyanosis, pallor, and/or marked hypotonia.”
