Narkomed GS Anesthesia Machine

  • Narkomed GS Anesthesia Machine

The Drager Narkomed GS is equipped with a single monitor screen that provides volume, pressure, and oxygen data. All monitored parameters and alarm messages are shown on a bright, easy-to-read display. The pneumatic system can simultaneously deliver up to four gases and one anesthetic agent (from a selection of up to three). Oxygen and nitrous oxide are standard, while air, carbon dioxide, and oxygen-helium are optional gases. Gas is supplied to the system through pipelines and cylinders. The system is equipped with illuminated flow tubes for accurate gas delivery measurement in poor light conditions.
