|Other names: Tracheal tug sign|
|Differential diagnosis||Aneurysm of the aortic arch.|
Oliver's sign is elicited by gently grasping the cricoid cartilage and applying upward pressure while the patient stands with his or her chin extended upward. Due to the anatomic position of the aortic arch, which overrides the left main bronchus, a downward tug of the trachea may be felt if an aneurysm is present. It is also seen in light anesthesia.
