Studies of Respiratory Physiology in the Newborn Infant. III. Measurements of Mechanics of Respiration1

Abstract

Considerable attention has recently been fo- cused on the mechanical factors in respiration of normal adults and of those with respiratory ab- normalities. This report presents observations on the mechanics of respiration in 23 normal newborn infants and 2 infants critically ill with-neonatal respiratory distress. The data are derived from simultaneous measurements of tidal volume and intraesophageal pressure changes.
