The GE Datex-Ohmeda E-Caio Gas Module employs the sidestream method to measure airway gases and calculates balance gas values. It samples all parameter values near the patient's airway using a single gas sampling line and offers numerical and graphical trends, aiding clinical decision-making. Additionally, it automatically detects occlusions and provides values for Static Plat, Static PEEPi+e, and Static Compliance. The module is ideal for anesthesia and critical care, with water separation systems to streamline workflow.
