[Development and interrelations between certain respiratory and biochemical parameters in normal neonates].

Abstract

The authors investigated the development and interrelations of respiratory and biochemical parameters of normal neonates during the adaptation period from 15 minutes to the 7th day after delivery. They found that the correlations of oxygen consumption, carbon dioxide output, respiratory volume and minute ventilation are positive and independent on the time of assessment. These respiration parameters are independent on the glucose, lactate and pyruvate levels, on the respiratory quotient and pH and pCO2. The authors characterize the similarity of the trend of individual parameters and the variability of normal values.
