The Edan 9960LGE-00 is a high-performance, single-patient-use mask designed for effective mainstream end-tidal CO2 (EtCO2) monitoring. Specifically engineered for non-intubated patients, this large adult mask allows for simultaneous oxygen delivery and precise EtCO2 measurement without the risk of re-breathing or gas mixing common in sidestream systems. It is compatible with the CapnoStat 5 Mainstream ETCO2 Module and a wide range of Edan patient monitors, providing high-fidelity capnography waveforms in emergency, surgical, and intensive care environments.
