1Preventing Postoperative Pulmonary Complications: The Role of the Anesthesiologist

1Effects of Respiratory Muscle Incoordination: Fig. 1 of Reference 1

1This model illustrates the consequence of respiratory muscle in coordination with respect to lung function impairment. The midpoint of horizontal bar represents lung volume from low [residual volume, RV] to high [TLC]. Normal chest wall expansion reflects coordinated inspiration (lower left) and his associated with efficient lung volume change. Reduced coordination associated with anesthesia is depicted by bar tilting, consistent with chest wall distortion and lung expansion impairment. This problem with muscle coordination can extend into the postoperative. Particularly with thoracic abdominal surgeries.
