V. Balaraman et al., END-TIDAL CARBON-MONOXIDE IN NEWBORN-INFANTS - OBSERVATIONS DURING THE 1ST WEEK OF LIFE, Biology of the neonate, 67(3), 1995, pp. 182-185
Serial end-tidal carbon monoxide corrected for ambient CO (ETCO(c)) le
vels were measured in an ethnically diverse population of 87 normal ne
wborn infants during the first 5 days of life. The results demonstrate
a progressive reduction in ETCO(c) from 1.6 +/- 0.4 to 0.8 +/- 0.2 pp
m. These levels were unrelated to ethnicity, but were inversely relate
d to serum bilirubin levels. We conclude that ETCO(c) is not a useful
indicator for predicting the course of transitional hyperbilirubinemia
in the normal newborn infant.
