Mindray Datascope Gas Module 3 Features

The Mindray Datascope Gas Module 3 is a companion to several patient monitors. The Gas Module 3, commonly called the Datascope GM3, 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 for adult/pediatric water trap, and 120 mL/min with neonatal water trap.
  • 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.
