Lung Mechanics in Normal Infants and Infants with Congenital Heart Disease

The results of a study of pulmonary mechanics in 24 normal infants and 28 infants with congenital heart disease aged 1 to 32 weeks are presented. The two groups were matched for length and weight. The diagnosis of the infants with congenital heart disease varied from simple stenoses to complex septal defects and transpositions. 6 infants were studied before and after operation designed to improve their haemodynamic situation.
