[Are infant resistant to carbon monoxide poisoning?]

A 20 year old woman and her 13 weeks old infant were found in the same place close together in a house fire. As soon as possible, on-the-spot treatment was initiated simultaneously for both victims, i.e. oxygen (100% FIO2), using endotracheal intubation and mechanical ventilation for the mother, with hyperbaric oxygen when in the hospital, and by facial mask for the baby. On admission (35 minutes after discovery in the fire), the mother remained comatose, whereas the baby showed only moderate neurologic abnormalities. The initial laboratory assessment showed a pH of 7.12 for the mother and 7.06 for the baby.
