ResMed ClimateLineAir 11 Oxy Heated Tube with Oxygen Port

The ResMed ClimateLineAir 11 Oxy is a heated tubing system for CPAP and BiPAP therapy, designed specifically for AirSense 11 and AirCurve 11 devices. It works like the standard ClimateLineAir 11 tube but adds an integrated oxygen port that allows supplemental oxygen to be delivered directly into the airflow without additional adapters.

The tubing is slim and flexible, measuring about 2 m (6 ft 6 in) in length with a 15 mm inner diameter, and supports pressures up to 30 cm H₂O. Its heated design helps prevent condensation (“rainout”) inside the tube, while Climate Control technology works in Auto or Manual mode to regulate temperature (≈16–30 °C / 60–86 °F) and maintain stable humidity (≈85% in Auto). A safety cut-off prevents overheating above 41 °C (106 °F).
