ABSTRACT

  • Airway devices are curved, hollow tools placed on the tongue via the oral or nasal route, enabling continuous airflow between the tongue and the pharynx.
  • Bag-valve mask systems are widely used in emergencies for manual ventilation due to their simplicity, portability, and ability to deliver high oxygen concentrations.
  • Supraglottic airway devices are airway equipment that allow patients to be ventilated and anesthetic gases to be administered without being placed in the trachea.
  • Endotracheal tubes are the tubes inserted into trachea and used for passing the inhalation gases and anesthetic agents. In murphy tubes, a hole named Murphy’s hole exists which provides continuation of ventilation in case of the tube touches carinae or trachea.
  • Laryngoscopes are devices designed for examining larynx and inserting endotracheal tube into trachea with bare eye. In terms of the shape, blades are classified into two groups, curved (Macintosh) and flat (Miller).
  • Videolaryngoscopes are the new devices developed in order to ease the endotracheal intubation difficulties and ensure the secure airway by using microcameras and monitors.
  • Fiberoptic Bronchoscope, is an airway device containing a longitudinal aspiration channel and a seperate working channel, optic fiber bundle package in a flexible tube, displaying lens on the tip and a lever manipulating the tip.
