Abstract
Dr. Stephen Wetmore, Coroner, Ministry of the Solicitor General, asked DCIEM to investigate the possibility that carbon dioxide buildup may have been a predisposing factor in the death of an infant. This is an account of the circumstances surrounding the death, the methods used to examine the hypothesis, the results and a discussion with recommendations regarding the results. The four-month old infant had just been released from the hospital after a serious respiratory infection. He was transported home in an infant carrier in the back seat of the car. The carrier was covered with a quilted blanket to protect the baby from the sun. Upon arrival at home, the infant was not breathing and after some brief resuscitative efforts was rushed to hospital where he was resuscitated in the emergency department. The baby died three days later with the post-mortem indicating pneumonia and tracheal infection. CO2 rebreathing has been considered as a causal factor in some infant deaths. The rebreathing is usually associated with the position of the baby's face in relation to bedding, the material and thickness of the bedding and the convective air flow conditions near the baby's face. Dr. Wetmore provided the infant carrier, the blanket and the baby's clothing. DCIEM developed experimental methods to estimate the baby's possible exposure to carbon dioxide. TRUNCATED
