Drager Vamos Features

The Drager Vamos is a variable anesthetic gas monitor used for measuring and monitoring the CO2 concentration, functional oxygen saturation, pulse rate, and the concentrations of N2O, and the following volatile anesthetic agents: Halothane, Enflurane, Isoflurane, Sevoflurane, and Desflurane. The display on the Drager Vamos shows Real-time curve CO2, Inspiratory concentration FiCO2, End-Expiratory concentration FetCO2, Functional oxygen saturation SpO2, Pulse rate, Inspiratory concentration FiN2O, End-expiratory concentration FetN2O, and the concentrations of anesthetic agents.

  • Inferred light measurement from sidestream samples.
  • Measured Parameters: CO2, N2O, SpO2, and 5 anesthetic agents.
  • Gas measurement: breath-to-breath resolution.
  • High-contrast amber electroluminescent display.
  • 5” diagonal display.
