Abstract
Summary: A modification of the open circuit CO‐method was developed for determination of the total amount of haemoglobin in newborn infants. Simultaneous determinations of the COHb level, the pulmonary CO elimination and the total haemoglobin were performed on 32 full‐term newborn infants. The rate of haemoglobin catabolism was calculated from the CO elimination and the total haemoglobin on the assumption that CO is formed mainly from degraded haemoglobin and is eliminated quantitatively in the expired air.An evaluation of the COHb level as a quantitative measure of haemolysis was made.
