Unexpanded alveoli cause decreased thoracic volume.
In older infants and children, a good inspiratory chest film is one in which the relationship of the 6th anterior rib ends intersect the domes of the diaphragm. This may be difficult to evaluate in the neonate where proper positioning is difficult because the neonate is connected to a number of life support systems. Because the volume of the thorax is decreased in an expiratory film, the following are seen: increased pulmonary opacity, confluent and prominent pulmonary vasculature shadows, and an increase in the size and prominence of the heart and mediastinal contents.
