Bronchoscopes: Endoscopes for the visualization of the interior of the bronchi.Fiber Optic Technology: The technology of transmitting light over long distances through strands of glass or other transparent material.Bronchoscopy: Endoscopic examination, therapy or surgery of the bronchi.Equipment Contamination: The presence of an infectious agent on instruments, prostheses, or other inanimate articles.Bronchography: Radiography of the bronchial tree after injection of a contrast medium.Hospital Bed Capacity, 100 to 299Iodophors: Complexes of iodine and non-ionic SURFACE-ACTIVE AGENTS acting as carrier and solubilizing agent for the iodine in water. Iodophors usually enhance bactericidal activity of iodine, reduce vapor pressure and odor, minimize staining, and allow wide dilution with water. (From Merck Index, 11th ed)Disinfection: Rendering pathogens harmless through the use of heat, antiseptics, antibacterial agents, etc.Bronchi: The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA. They include the largest two primary bronchi which branch out into secondary bronchi, and tertiary bronchi which extend into BRONCHIOLES and PULMONARY ALVEOLI.Foreign Bodies: Inanimate objects that become enclosed in the body.Hemoptysis: Expectoration or spitting of blood originating from any part of the RESPIRATORY TRACT, usually from hemorrhage in the lung parenchyma (PULMONARY ALVEOLI) and the BRONCHIAL ARTERIES.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.Tracheal NeoplasmsEquipment Design: Methods of creating machines and devices.Gastroscopes: Endoscopes used for examining the interior of the stomach.Thoracoscopes: Endoscopes for examining the pleural cavity.Bronchoalveolar Lavage: Washing out of the lungs with saline or mucolytic agents for diagnostic or therapeutic purposes. It is very useful in the diagnosis of diffuse pulmonary infiltrates in immunosuppressed patients.Solitary Pulmonary Nodule: A single lung lesion that is characterized by a small round mass of tissue, usually less than 1 cm in diameter, and can be detected by chest radiography. A solitary pulmonary nodule can be associated with neoplasm, tuberculosis, cyst, or other anomalies in the lung, the CHEST WALL, or the PLEURA.Bronchial Neoplasms: Tumors or cancer of the BRONCHI.Airway Obstruction: Any hindrance to the passage of air into and out of the lungs.Sterilization: The destroying of all forms of life, especially microorganisms, by heat, chemical, or other means.Serratia Infections: Infections with bacteria of the genus SERRATIA.Pulmonary Medicine: A subspecialty of internal medicine concerned with the study of the RESPIRATORY SYSTEM. It is especially concerned with diagnosis and treatment of diseases and defects of the lungs and bronchial tree.Airway Management: Evaluation, planning, and use of a range of procedures and airway devices for the maintenance or restoration of a patient's ventilation.Therapeutic Irrigation: The washing of a body cavity or surface by flowing water or solution for therapy or diagnosis.Hospital Bed Capacity, 500 and overBiopsy, Needle: Removal and examination of tissue obtained through a transdermal needle inserted into the specific region, organ, or tissue being analyzed.Laryngeal Masks: A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.Tracheal StenosisMediastinum: A membrane in the midline of the THORAX of mammals. It separates the lungs between the STERNUM in front and the VERTEBRAL COLUMN behind. It also surrounds the HEART, TRACHEA, ESOPHAGUS, THYMUS, and LYMPH NODES.
