The Respironics 3475-00 is a specialized sidestream CO2 sampling kit designed for intubated patients requiring continuous end-tidal CO2 monitoring. This kit features integrated Nafion and dehumidification tubing, which effectively manages moisture and humidity in the breath sample to ensure consistent diagnostic accuracy. Engineered for use with the LoFlo ETCO2 Side Module, it provides a reliable connection between the patient's airway and the sensor, protecting the module from liquid ingress while maintaining high-fidelity capnography waveforms in high-acuity environments.
