Mechanisms of sudden infant death and the contamination of inspired air with exhaled air

J A JA Corbyn

Med Hypotheses 54(3):8 (2000) PMID 10783464

The physiological effects on an infant of repeatedly sleeping in an environment consisting of a mixture of exhaled air and fresh air is examined. It is found that adaptation can be predicted. A possible outcome of the adaptation is shown to be the development of hypoxia when the conditions change during sleep from a state with carbon dioxide contamination of inspired air to one without. This hypoxia can be associated with apnoea: this apnoea can provide an explanation for some instances of sudden infant death. This explanation is consistent with the known epidemiology and environmental associations of a proportion of sudden infant death syndrome. Safety precautions for the prevention of re-breathing are given.
