Tracheostomy: Surgical formation of an opening into the trachea through the neck, or the opening so created.Tracheotomy: Surgical incision of the trachea.Tracheal StenosisTracheal DiseasesDilatation: The act of dilating.Intubation, Intratracheal: A procedure involving placement of a tube into the trachea through the mouth or nose in order to provide a patient with oxygen and anesthesia.Respiration, Artificial: Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).Ventilator Weaning: Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.Surgical Stomas: Artificial openings created by a surgeon for therapeutic reasons. Most often this refers to openings from the GASTROINTESTINAL TRACT through the ABDOMINAL WALL to the outside of the body. It can also refer to the two ends of a surgical anastomosis.Laryngostenosis: Developmental or acquired stricture or narrowing of the LARYNX. Symptoms of respiratory difficulty depend on the degree of laryngeal narrowing.Airway Obstruction: Any hindrance to the passage of air into and out of the lungs.Respiratory Insufficiency: Failure to adequately provide oxygen to cells of the body and to remove excess carbon dioxide from them. (Stedman, 25th ed)Device Removal: Removal of an implanted therapeutic or prosthetic device.Intensive Care Units: Hospital units providing continuous surveillance and care to acutely ill patients.Respiratory Tract Fistula: An abnormal passage communicating between any component of the respiratory tract or between any part of the respiratory system and surrounding organs.Bronchoscopy: Endoscopic examination, therapy or surgery of the bronchi.Burns, Inhalation: Burns of the respiratory tract caused by heat or inhaled chemicals.Trachea: The cartilaginous and membranous tube descending from the larynx and branching into the right and left main bronchi.Multiple Trauma: Multiple physical insults or injuries occurring simultaneously.Critical Illness: A disease or state in which death is possible or imminent.Critical Care: Health care provided to a critically ill patient during a medical emergency or crisis.Laryngeal Diseases: Pathological processes involving any part of the LARYNX which coordinates many functions such as voice production, breathing, swallowing, and coughing.Brachiocephalic Trunk: The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.Tracheoesophageal Fistula: Abnormal passage between the ESOPHAGUS and the TRACHEA, acquired or congenital, often associated with ESOPHAGEAL ATRESIA.Cricoid Cartilage: The small thick cartilage that forms the lower and posterior parts of the laryngeal wall.Larynx: A tubular organ of VOICE production. It is located in the anterior neck, superior to the TRACHEA and inferior to the tongue and HYOID BONE.Intensive Care: Advanced and highly specialized care provided to medical or surgical patients whose conditions are life-threatening and require comprehensive care and constant monitoring. It is usually administered in specially equipped units of a health care facility.Insufflation: The act of blowing a powder, vapor, or gas into any body cavity for experimental, diagnostic, or therapeutic purposes.Pneumonia, Aspiration: A type of lung inflammation resulting from the aspiration of food, liquid, or gastric contents into the upper RESPIRATORY TRACT.Vascular Fistula: An abnormal passage between two or more BLOOD VESSELS, between ARTERIES; VEINS; or between an artery and a vein.Respiratory Therapy Department, Hospital: Hospital department which is responsible for the administration of diagnostic pulmonary function tests and of procedures to restore optimum pulmonary ventilation.
