Computational simulation of accumulation of expired air in the infant cot

Accumulation and re-breathing of CO2 in expired air has been suggested as o ne possible explanation for the strong association between prone sleeping p osition and sudden infant death syndrome (SIDS). This preliminary study app lying a modern computational fluid dynamics (CFD) program to simulate the a erodynamics in an infant cot supports the idea that accumulation of expired ail may occur in the prone position. The literature dealing with the poten tial association between re-breathing of accumulated CO2 and SIDS is briefl y reviewed.
