The Respironics 6063-00 is a high-precision, single-patient-use (SPU) airway adapter designed for mainstream CO2 monitoring. Engineered for use with the CapnoStat 5 ETCO2 Mainstream Module, this adapter provides a transparent window for infrared sensing, allowing for real-time capnography without the need for gas sampling lines. It is optimized for adult and pediatric patients using endotracheal tubes larger than 4mm, ensuring accurate end-tidal CO2 readings while maintaining low dead space in high-acuity clinical settings.
