title: End-tidal carbon monoxide in newborn infants: observations during the 1st week of life.
abstract: Serial end-tidal carbon monoxide corrected for ambient CO (ETCOc) levels were measured in an ethnically diverse population of 87 normal newborn infants during the first 5 days of life. The results demonstrate a progressive reduction in ETCOc from 1.6 +/- 0.4 to 0.8 +/- 0.2 ppm. These levels were unrelated to ethnicity, but were inversely related to serum bilirubin levels. We conclude that ETCOc is not a useful indicator for predicting the course of transitional hyperbilirubinemia in the normal newborn infant.
