Chapter 21 Flail Chest Figure 21 -1. Flail chest. Double fractures of three or more adjacent ribs produce instability of the chest wall and paradoxical motion of the thorax. Inset, Atelectasis, a common secondary anatomic alteration of the lungs. Slide 1 Copyright © 2006 by Mosby, Inc.

Overview of the Cardiopulmonary Clinical Manifestations Associated with FLAIL CHEST The following clinical manifestations result from the pathophysiologic mechanisms caused (or activated) by Atelectasis (see Figure 9 -7) and Pneumonic Consolidation (see Figure 9 -8)— the major anatomic alterations of the lungs associated with flail chest (see Figure 21 -1).
