Lung and alveolar ventilation, gas exchange and values of respiratory efficiency under normal conditions and during inspiration of gas mixtures with 41% O2 and 14.5% O2 in N were studied in healthy children 6-7 yr old. The increase in alveolar ventilation (AV), AV/RMV ratio and decrease in the physiological dead space to the end of the hyperoxic period may indicate the positive influence of 41% O2 on respiration of children.
