tracheostomy /tra·che·os·to·my/ (tra″ke-os´tah-me) creation of an opening into the trachea through the neck, with the tracheal mucosa being brought into continuity with the skin; also, the opening so created.

Tracheostomy
An opening through the neck into the trachea through which a tube may be inserted to maintain an effective airway and help a patient breathe.
tracheostomy
[trā′kē·os′təmē]
Etymology: Gk, tracheia + stoma, mouth
an opening through the neck into the trachea through which an indwelling tube may be inserted. After tracheostomy the patient's chest is auscultated for breath sounds indicative of bilateral air exchange and pulmonary congestion, mucous membranes and fingertips are observed for cyanosis, oxygenation is monitored with pulse oximeters, and humidified oxygen is given via a trach collar placed over the tracheostomy tube. The patient is reassured that the tube is open and that air can pass through it. The tube is suctioned as needed to keep it free from tracheobronchial secretions by using a suction catheter attached to a Y-connector. The catheter is rotated, and intermittent suction is applied for no longer than 10 seconds. Complications of tracheostomy include pneumothorax, respiratory insufficiency, obstruction of the tracheostomy tube or its displacement from the lumen of the trachea, pulmonary infection, atelectasis, tracheoesophageal fistula, hemorrhage, and mediastinal emphysema. If the procedure was done as an emergency, the tracheostomy is closed after normal breathing is restored. If the tracheostomy is permanent, such as with a laryngectomy, the patient is taught self-care. Compare tracheotomy.

tracheostomy (trā´kēos´tōmē),
n 1. the formation of an opening into the trachea and the suturing of the edges of the opening to an opening in the skin of the neck.
2. surgical formation of an opening into the trachea, usually through the tracheal rings below the cricoid cartilage, to give the patient an airway.

tracheostomy
creation of an opening into the trachea through the neck, with insertion of an indwelling tube to facilitate passage of air or evacuation of secretions. The procedure may be an emergency measure or an elective one.
tracheostomy tube
two identical down-curving, semicircular tubes are fitted one inside the other. They both have wide flanges which fit against the skin when the tubes are inserted in and down through the tracheostomy incision. When the tubes are snugly in position the inner tube is rotated through 180° making the tube self-retaining.
tracheostomy
Surgery The incision in the anterior wall of the trachea to establish an airway Indications Upper airway obstruction–due to congenital lesions or acute events-eg foreign body, diphtheria, bilateral voal cord paralysis,
laryngeal neoplasms, regional trauma, edema, or anaphylactic reactions, or inability to handle upper or lower respiratory secretions Pros Relieves obstruction, ↓ dead air space, therefore the work required for effective ventilation; facilitates
lavage Cons Loss of effective cough; ↑ susceptibility to infection, especially with Pseudomonas spp.
