Respiratory and chest wall mechanics in very preterm infants

Data on static compliance of the chest wall (Ccw) in preterm infants are scarce. We characterized the static compliance of the lung and Ccw to determine their relative contribution to static compliance of the respiratory system in very preterm infants at 36 wk postmenstrual age. We also aimed to investigate how these compliances were influenced by the presence of bronchopulmonary dysplasia and impacted breathing variables.
