Overview
ClimateLineAir Oxy is ResMed's heated tube for people who add supplemental oxygen to their AirSense 10 or AirCurve 10 therapy. Oxygen joins through a connector built into the tube, and the warmed air keeps your humidity comfortable all the way to the mask.
It's ResMed part 37357, made for the AirSense 10 and AirCurve 10 families. Next to the standard ClimateLineAir, it's a little shorter with a wider bore. You get one tube, ready to connect.
Key features:
- Recognised on connect: Your machine recognises the heated tube once the cuff clicks home, and confirms it with a message on its screen.
- Climate Control Auto: Paired with the HumidAir humidifier, it lets your machine manage warmth and humidity together for a steady night.
- Adjustable tube heat: Stay on Auto, or nudge the tube's temperature up or down from your machine's comfort settings, or turn the heat off.
- Slim profile: ResMed says it keeps the slim profile of its standard heated tube, so adding oxygen doesn't bring a bulkier hose to bed.
- Health Canada listed: It appears on Health Canada's device records under every AirSense 10 and AirCurve 10 licence, so it's cleared for sale here.
It's made for AirSense 10 and AirCurve 10 users whose care plan includes oxygen at night, and who want heated humidity at the same time. If you don't use oxygen, the standard ClimateLineAir is the simpler and more fitting choice for your machine.
Note: Not for the AirSense 11 or AirCurve 11, which use the ClimateLineAir 11 Oxy. Your machine sets the maximum oxygen flow, so check its user guide before connecting a supply.
How it works
Setting up
With the machine on, hold the cuff to the air outlet and push until you feel it click, then connect your mask to the other end. Only the cuff end belongs on the machine. To add oxygen, lift the cap off the connector and push your oxygen line on firmly.
Oxygen safety
Turn the machine on and wait until air is moving before you open the oxygen supply. At the end of the night, close the oxygen first and switch the machine off second, so unused oxygen can't collect inside the machine and become a fire risk. Never use oxygen while smoking or near an open flame.
Weekly care
ResMed's routine is once every week: warm water with a mild detergent, a full rinse, then air drying out of direct sunlight. Hold the cuff, not the hose, when disconnecting, and replace the tube if you see any holes, tears, or cracks.

Everything you need to know about the ResMed ClimateLineAir Oxy Heated Tubing for AirSense 10 and AirCurve 10
Oxygen and heated humidity together
If supplemental oxygen is part of your therapy, this tube lets you keep the comfort of a heated hose. Oxygen and warm, humidified air travel to your mask together through the same line, with no second hose to manage.
Condensation at the mask
Humid air that cools on its way to you can collect as droplets in the hose and mask, which ResMed calls rainout. With Climate Control on Auto, the system protects against it while holding humidity at a steady level.
Use without oxygen
On nights without oxygen, press the cap firmly onto the connector and the Oxy works as an ordinary heated tube. That means one hose covers every night, whether or not your oxygen supply is in use.

Built-in oxygen connector
Your oxygen line pushes onto a connector built into the cuff at the machine end, so nothing extra sits in the circuit.
Tethered cap
A cap attached to the cuff closes the oxygen connector on nights you don't need it, so it can't go missing.
Automatic humidity
With the HumidAir tub fitted, the machine balances tube warmth and moisture for you through the night.
Even warmth
ResMed designed the tube to deliver the temperature you set at your mask, rather than only at the machine.
Frequently Asked Questions
Does this fit an AirSense 11 or AirCurve 11?
No. Those machines take their own ClimateLineAir 11 Oxy from ResMed. This tube fits the AirSense 10 and AirCurve 10, and it doesn't fit S9 machines either.
Do I need the Oxy or the standard tube?
Only choose the Oxy if oxygen is added to your CPAP air. It's slightly shorter than the standard ClimateLineAir and has a wider bore. Without oxygen, the standard tube does the same job.
How should I wash the Oxy tube?
ResMed's weekly routine is the same as for its standard heated tube: warm water and mild detergent, a thorough rinse, then air drying out of the sun. ResMed gives no separate step for the oxygen connector.
How long does the Oxy tube last?
ResMed's design life for the Oxy is 6 months, matching the standard tube. Inspect it regularly and replace it early at the first hole, tear, or crack.
How much oxygen can I add?
The limit is set by your machine, not the tube. ResMed caps the AirSense 10 at 4 L/min of supplemental oxygen, while AirCurve 10 limits vary by model and mode, so check your machine's user guide.
