tracheal aspiration

see transtracheal aspiration.

tracheal band sign

on contrast radiography of a dilated esophagus, the impression made ventrally by the trachea.

tracheal collapse, collapsing trachea

a disorder of the tracheal membrane (trachealis muscle) or tracheal rings that results in a functional tracheal stenosis. Affected dogs, usually of miniature or toy breeds, have a cough and reduced exercise intolerance. See also goose honk cough.

tracheal compression

pressure on the trachea sufficient to cause displacement and reduction in caliber, usually inside the thorax; most readily detected radiographically.

tracheal cough

a nonproductive, or only slightly productive, resonant cough, often occurring in paroxysms and easily elicited by pressure on the cervical trachea. Typically associated with tracheitis.

tracheal duct

paired lymphatic ducts running down the side of the trachea, commencing at the retropharyngeal lymph nodes, receiving tributaries from other nodes of the head and neck and terminating in either the thoracic duct or the jugular or other vein at the entrance to the chest.

tracheal hypoplasia

a congenital defect in brachycephalic dogs in which the tracheal lumen is greatly reduced in size. Bronchopneumonia commonly occurs.

tracheal inflammation

see tracheitis.

tracheal intubation

refers usually to the passage of an endotracheal tube for the purposes of anesthesia, resuscitation or external control of respiration for any other reason. See also tracheal tube (below).

tracheal lavage, tracheal wash

introduction of a tracheal catheter via a cutaneous incision between two tracheal rings, passage of the catheter to the bronchi, introduction of normal saline, aspiration of the saline, retrieval of the catheter.

tracheal percussion

a sharp percussion stroke on the trachea creates a sound which can be auscultated over the lung area.

tracheal rupture

due usually to blunt trauma; there is escape of air into surrounding tissues which results in subcutaneous and mediastinal emphysema.

tracheal stenosis

may be congenital or acquired, resulting from trauma or surgical procedures on the trachea. Causes respiratory distress, coughing, and secondary infections of the upper respiratory tract.

tracheal transection

occurs as a result of trauma, in cats particularly from hyperextension of the head and neck, causing dyspnea.

tracheal tube

a metal tube used in horses that have a long-term obstruction of the upper respiratory system. Different to a tracheotomy tube it is a flattened tube fixed to a broad flange with suture holes at its edge and a bend of 90° at 0.5 inch from the flange. See also endotracheal tube.
