Etymology: Gk, tracheia, rough artery; ME, toggen
an effect of an aortic aneurysm in which the trachea is pulled downward with each heart contraction.
A slight downward movement of the trachea with each inspiratory effort, resulting from descent of the diaphragm in a person with a low, flat diaphragm. The sign may also be present as a result of the proximity of an aortic aneurysm to the trachea. It should not be confused with the pulsations from a normal vessel beneath the trachea. Synonym: Oliver sign
