A Four-Month-Old Infant Suffocated In His Sleep From Positional Asphyxia. The Baby Was Found Face Down On A Foam Wedge Pillow Called A Sleep Positioner. The Author Was Engaged To Evaluate The Sleep Positioner Product For Its Potential To Cause Carbon Dioxide (Co2) Re-Breathing In Infants. Prior Research On This Subject Had Already Established A Reliable Method Of Simulating Infant Breathing And Measurement Of Respiratory Gas Constituents Using A Mechanical Breathing Model. Guided By This Research, A Mechanical Breathing Model And Gas Sampling Apparatus Was Coupled To A Mannequin Representing The Child In This Matter. The Mannequin Was Placed In Face-Down And Sidefacing Positions On The Sleep Positioner Product And Twelve Other Surfaces, Including A Plain Cotton Sheet As The Baseline. The Sleep Positioner Product Produced The Highest (And Most Dangerous) Level Of Co2 Re-Breathing, More Than Three Times The Baseline Level. Factors Contributing To Co2 Re-Breathing Are Discussed.
