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).

CPAP Supplies Guide

Clean the ClimateLineAir 11 Oxy weekly with warm water and a mild solution like the Neutralizing Pre-Wash. Always rinse thoroughly and let it air dry.
Avoid cleaning the tubing in dishwashers or washing machines. Instead, use the CPAP tube and mask cleaning brush for thorough care without damaging the heating element.
Add a CPAP hose cover to insulate the heated tubing further and minimize condensation buildup during cooler nights.
Replace the ClimateLineAir 11 Oxy about every 6 months, or sooner if cracks, leaks, or reduced heating are noticeable. Use the Part Finder tool to confirm compatibility.
When using supplemental oxygen, always keep the port cap in place if oxygen is not connected. This prevents leaks that could lower therapy pressure.
Never smoke or use open flames near the oxygen port, as supplemental oxygen increases fire risk.
Use the tubing with the AirSense 11 humidifiers for full Climate Control. While it can run without humidification, pairing both functions reduces dryness.
Pair the ClimateLineAir 11 Oxy with compatible CPAP masks to ensure stable airflow and comfortable therapy, even at higher pressures.
If you rely on portable power, keep in mind that heated tubing draws extra energy. Explore options in the CPAP power solutions collection to extend runtime during travel or outages.
For added comfort with CPAP Masks masks, use CPAP strap covers to reduce skin marks while benefiting from climate-controlled therapy.
Inspect tubing connections regularly at both ends. If you hear hissing or feel air leaks, reseat the connectors and verify they lock securely with the device and mask.

Product Features

The ClimateLineAir 11 Oxy is a heated CPAP and BiPAP tube with a built-in oxygen connector. It delivers warm, humidified air while allowing direct connection of supplemental oxygen without extra adapters. If oxygen is not required, the port is capped to avoid leaks. This design simplifies setup and reduces the need for separate connectors.

The tubing is designed for use with the ResMed AirSense 11 and AirCurve 11 series. When connected, the device displays “ClimateLine connected” on the screen to confirm recognition. It delivers heated air to compatible masks with or without oxygen. It is not intended for use with older CPAP models unless specified otherwise.

When paired with the HumidAir 11 humidifier, the tube activates Climate Control. In Auto mode, temperature defaults to about 27 °C with relative humidity maintained near 85 percent to prevent condensation. In Manual mode, you can adjust tube temperature between 16 °C and 30 °C and select humidity independently across eight levels.

Prevention of Condensation and Rainout

The built-in heating element keeps air temperature stable from machine to mask, helping prevent moisture buildup inside the hose. This reduces the chance of rainout and gurgling. Auto mode offers consistent results, while Manual mode may need adjustments depending on room conditions.

Safety Features and Oxygen Warnings

A temperature sensor prevents overheating by cutting off power at 41 °C. If using oxygen, avoid open flames and smoking due to fire risk. Always keep the oxygen port capped when not in use to prevent leaks that can affect therapy.

Tube Dimensions and Specifications

The tubing is about 2 meters (6 ft 6 in) long with a 15 mm inner diameter. Its slim, flexible build helps reduce drag on the mask. It supports pressures up to 30 cm H₂O and is made for regular daily use.

Operating Environment and Power Use

Designed to operate in 5 °C to 35 °C environments. Heating pulls power from the CPAP unit, reducing battery life if using portable sources. While usable without humidification, the tube performs best when paired with a humidifier.

Setup and Connection Process

Connect the cuffed end to the machine outlet until it clicks and displays 'ClimateLine connected.' Attach the other end to your mask. Remove the oxygen cap only if connecting an oxygen hose, and confirm all connections are secure before starting therapy.

Cleaning and Maintenance Guidelines

Wash the tubing weekly using warm water and mild soap, then rinse and air-dry away from sunlight. Do not use a dishwasher, washing machine, or brushes. Regular inspections help identify cracks, leaks, or worn parts that need replacement.

Replacement and Service Life

ResMed recommends replacing the tube every six months or sooner if signs of wear appear. Common indicators include reduced heating, visible damage, or persistent leaks. Using damaged tubing may compromise airflow and therapy effectiveness.

Hospital and Home Use

Intended for single-patient use at home, but can be reprocessed in clinical settings. In the U.S., it’s a prescription item and must be used as directed in the Air11 user manual to ensure safety and compliance.

Compatibility with Humidifier Use

Pairs with the HumidAir 11 humidifier to enable full Climate Control. It still heats air when used without humidification, but may lead to dryness. For optimal comfort, use the tubing alongside a humidifier to balance moisture and warmth.

Power Consumption and Battery Life

The tubing draws power directly from the connected machine. Heating increases energy use, which may shorten battery runtime when traveling. Factoring this into backup power plans helps avoid therapy interruptions.

FAQs

Yes. Heated CPAP tubing with an oxygen connector, such as the ClimateLineAir 11 Oxy, is designed to allow oxygen therapy to be combined with CPAP therapy. The oxygen line connects to the built-in port of the tube, eliminating extra adapters. Oxygen and humidified air mix before reaching the mask, keeping therapy simple and efficient.

The ClimateLineAir 11 Oxy has a dedicated oxygen port built into the tube. Connect the oxygen tubing from your source directly to this port. If oxygen is not in use, the port must be sealed with the included cap to prevent leakage or pressure loss. Oxygen should never be connected directly to the mask or other points.

Rainout happens when warm, humid air cools inside the tubing, forming condensation. This can cause gurgling sounds and discomfort. Heated tubing like the ClimateLineAir 11 Oxy keeps air at a consistent temperature to reduce condensation. Additional steps include using Climate Control Auto mode, raising tube temperature, lowering humidity, or placing the device lower than your head.

Heated tubing includes wires and connectors, making it slightly heavier and sometimes less flexible than non-heated tubing. The ClimateLineAir 11 Oxy, however, has a slim, flexible profile designed to balance comfort and durability. While bulkier than standard tubing, its lightweight build minimizes drag on the mask during sleep.

Heated tubing costs more than standard tubing due to heating elements and oxygen connectors. Durability depends on care and cleaning. Many professionals recommend replacing CPAP tubing every 6–12 months, though this varies with use, cleaning, and visible wear like cracks or discoloration. Regular inspection and cleaning help extend its life.

If the tube does not warm, ensure it is securely connected to the CPAP device and Climate Control is active. In Manual mode, confirm the temperature is not set to Off or the lowest setting. If still unheated, check for broken connectors, bent pins, or cracks. Damaged tubes must be replaced.

Yes, but strict precautions apply. Oxygen supports combustion and must not be used near flames or smoking. The oxygen port and tubing must be tightly sealed and leak-free. The protective cap should remain in place if oxygen is not connected. Always follow manufacturer guidelines and medical advice when combining oxygen with CPAP therapy.

Yes. The ClimateLineAir 11 Oxy warms air even without a humidifier, helping reduce the sensation of cold airflow. Without humidification, however, no added moisture is provided, which may cause dryness in the mouth or nose. Best results usually occur when the heated tube is paired with the HumidAir humidifier.

Room temperature impacts condensation control. In colder rooms, air cools faster, raising the chance of rainout even with heated tubing. Raising tube temperature can counter this. In warmer or humid conditions, condensation risk is lower, though lowering humidity may help prevent excessive warmth or moisture. Climate Control Auto mode adapts, but extreme environments may still need manual adjustment.

The tubing draws power directly from the CPAP machine, with no external supply needed. Heating elements consume extra energy, reducing battery runtime if the CPAP is powered by a portable battery. Travel or backup battery use will see shorter operating time when heated tubing and humidification are active.

Yes. The ClimateLineAir 11 Oxy works exclusively with ResMed AirSense 11 and AirCurve 11 devices. Its specialized connector is not compatible with older CPAP models or other brands. Using it with unsupported machines may cause improper function, no heating, or equipment damage. Always match tubing to your CPAP model.
