Mindray Datascope Gas Module II Features

The Mindray Datascope Gas Module II is a companion to several patient monitors. The Gas Module II, commonly called the Datascope GM2, is capable of automatically identifying and measuring five anesthetic agents (Desflurane, Enflurane, Sevoflurane, Halothane, and Isoflurane, as well as N20, CO2, and O2. This unit monitors all gases via sidestream sampling.

  • 200 mL/min sample flow rate.
  • Uses a non-dispersive infrared analyzer to measure the absorption of the gas sample at seven infrared wavelengths.
  • 2.5-second sampling delay
  • Water trap that removes water and impurities from the patient sample.
  • Analyzes patient samples at a fixed rate.
