While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood.

When babies sleep face down, they may re-breathe exhaled carbon dioxide. Normally, rising carbon dioxide levels activate nerve cells in the brainstem, which stimulate the brain's respiratory and arousal centers. The baby then wakes up, turns his head, and breathes faster to get more oxygen.

SIDS babies, however, may fail to rouse. The model holds that SIDS occurs when three conditions exist simultaneously:. A baby is determined to have died from SIDS if no cause of death can be identified following a death scene investigation, an autopsy, and a review of the clinical history.
