The Anesthesia Gas Module provides valuable information on patient conditions and for anesthesia system management and ventilation.

The sidestream module is a great solution for monitoring anesthesia in procedures that involve infants and adults. The plug-in Anesthesia Gas Module expands measurement capabilities for DRE Waveline monitors and upgrades the Waveline Touch into a fully-featured O.R. Monitor. It also adds Automatic Agent ID to the Waveline Pro. For the accurate and continuous measurement of Automatic Agent ID, Anesthetic Agent Concentrations (HAL, ENF, ISO, SEV, DES), CO2, O2, N2O, MAC and Respiratory Rate.
