The Edan Respironics CO2/O2 Nasal/Oral Cannula (3471ADU-00) ensures complete metabolic tracking for adult patients who breathe interchangeably through the mouth or nose while requiring regular supplemental oxygenation. Engineered to lock directly into the factory LoFlo Sidestream ETCO2 module, this specialized system collects expired gases from both nasal and oral pathways simultaneously. It features an inline dehumidification system that pulls fluid condensation from sample lines, protecting diagnostic scanning benches and waveform data readouts against water blockage or transmission dropouts.
