The Edan 22.08.208023 is a plug-and-play multi-gas analysis module engineered for high-precision, real-time anesthesia gas monitoring on Elite series patient monitors. Utilizing genuine Masimo mainstream sensor technology, this hardware module measures carbon dioxide, nitrous oxide, and specialized anesthetic agents directly at the patient’s airway breathing circuit. Its direct-circuit measurement system eliminates the sampling delay associated with sidestream lines, delivering immediate physiological waveforms for surgical and critical care environments.
