Figure 1: Demonstration of sonographic airway confirmation via direct visualization of the endotracheal (ET) tube within the trachea. (a) High frequency linear array image of transverse airway at larynx. The arrow is pointing to ET tube in airway with reverberations posteriorly; (b) Another image of airway at larynx with high frequency linear array probe used to outline the ET tube; (c) Long axis parasagittal image of the airway using high frequency linear array probe, with direct visualization of the ET tube (arrow)
