n.
a surgical operation in which a hole is made into the trachea through the neck to relieve obstruction to breathing, as in diphtheria. A curved metal, plastic, or rubber tube is usually inserted through the hole and held in position by tapes tied round the neck. It may be possible for the patient to speak by occluding the opening with his fingers. The tube must be kept clean and unblocked. Tracheostomy is also used in conjunction with artificial respiration, when it serves not only to secure the airway but also provides a route for sucking out secretions and protects the airway against the inhalation of pharyngeal contents. See also minitracheostomy.
