The Edan Respironics CO2/O2 Nasal Cannula (3469PED-00) provides concurrent carbon dioxide tracking and supplemental oxygen administration for pediatric patients. Engineered to hook directly into the LoFlo Sidestream ETCO2 module, this premium dual-purpose cannula features micro-sized non-flared nasal prongs and built-in dehumidification tubing. It pulls moisture away from gas streams before it can enter the diagnostic optics, protecting tracking accuracy and respiratory waveforms against condensation occlusion or sensor signaling downtime.
