We carry a wide variety of reusable and disposable airway adapters for capnography etCO2 (end-tidal CO2) sensors. This particular disposable adapter (6063-00) is designed for adult and pediatric patients and it is compatible with our mainstream etCO2 sensors/modules, as well as the CAPNOSTAT 5 mainstream sensor by Philips Respironics. We also have this part available in neonatal (6312-00).
