Fig. 2
From: Chest wall mechanics before and after diaphragm plication
Synchrony between chest compartments. The figure shows the phases of breathing on both sides of the chest wall during quiet breathing before the operation and 6 months after unilateral diaphragmatic plication. We found that before the operation, the expansion of the abdominal rib cage was lagging behind the abdominal expansion, showing complete inward paradoxical movement during inspiration in both sides of the chest. After the operation that inward paradoxical movement disappeared in both sides, and resulted in complete synchronization of both sides following unilateral diaphragmatic plication
