The Respironics 3470PED-00 is a high-precision, single-patient-use sampling cannula designed for sidestream CO2 monitoring in pediatric patients. Engineered for use with the LoFlo ETCO2 Side Module, this oral/nasal cannula ensures accurate quantitative readings of end-tidal CO2 (EtCO2) while maintaining patient comfort during diagnostic monitoring. Its integrated sample cell and filter design streamline the setup process for Edan patient monitors and other compatible systems, providing a reliable solution for respiratory assessment in high-acuity and ambulatory settings.
