ResMed AirCurve 11 VAuto
How to set up the ResMed AirCurve 11 VAuto
From the box to your first night. Keep the user guide that came with your machine nearby: if anything here differs from it, follow the guide.
Check the box
You should find the AirCurve 11, a HumidAir 11 tub, tubing (ClimateLineAir 11 or standard), a 90W power supply and a travel bag. The label on the device names the model (VAuto, S or ASV); check it matches what your doctor prescribed.
Place it level and below your head
Set it on a stable, level surface lower than your head so any water runs back toward the machine, and keep the air inlet clear of bedding.
Connect the power
Plug the power cord into the back, connect it to the AC adaptor and plug into the wall. Keep it plugged in so your prescription can arrive wirelessly if your provider sends it that way. Do not connect a USB cable to the machine.
Attach the tubing
Push the tubing firmly onto the outlet connector at the back. The electrical end of ClimateLineAir 11 tubing goes on the machine, never on the mask.
Fill the tub
Remove the tub before filling. Use distilled water only in the Standard tub, or drinking-quality water in the Cleanable tub, up to the maximum line (380 mL). Use room temperature water, never hot. Close it and slide it into the side of the machine.
Do the pre-use check
ResMed's guide asks you to look over the machine, tub, tubing and mask for visible damage before use. With the tub in, tap MORE and then Run Warmup; the humidifier symbol should appear. Then check that air flows when you start therapy.
Connect your mask and check the fit
Attach the tubing to your mask, put it on, then tap MORE and run Mask Fit. A good seal means leak is under 24 L/min; adjust the cushion and headgear until you get it.
Pair myAir if you want it
Optional. Install the latest myAir app, tap Continue and follow the Bluetooth prompts; go to the MORE menu on the machine when the app asks. Tap Save when paired.
Start therapy
Press the Start Therapy/Standby button, or breathe normally if SmartStart is on. A pulse wave appears while it runs. To stop, remove the mask and press the button, or wait if SmartStop is on.
If you notice chest pain, severe headache, more breathlessness or bloating that does not settle, contact your prescribing doctor.
After setup: settings worth knowing
- Ramp Time: Starts at a lower pressure and rises to your prescribed pressures over the set time.
- Humidity Level: Sets how much moisture the humidifier adds: up for a dry nose or mouth, down for water in the mask.
- Climate Control: With ClimateLineAir 11 and the tub attached, Auto holds about 85% relative humidity and guards against rainout; Manual lets you set temperature and humidity yourself.
- Tube Temperature: Auto is 80 F (27 C); you can choose 60 to 86 F (16 to 30 C) or Off. Raising it is the first fix for rainout.
- Pressure Relief (EPR): Eases breathing out in CPAP mode. In VAuto mode the gap between inhale and exhale pressure is your prescribed pressure support instead.
- Mask: Selects the type of mask you use with the machine.
- Tube: Selects the type of tubing attached.
- SmartStart and SmartStop: Starts therapy when you breathe into the mask and stops it a few seconds after you take it off.
- Run Warmup: Heats the water before you start so the air is not cold or dry.
- Airplane Mode: Turns off wireless transmission for flights.
Supplies that can help
Distilled water is what most CPAP humidifier chambers are meant to be filled with, because it leaves little or no mineral scale behind.
The air inlet filter keeps dust and lint out of the machine and your airway; it is a cheap part that needs regular replacement.
Tubing with a built-in heating wire that keeps humidified air warm all the way to the mask, which is the main fix for rainout (water droplets …
The plain hose between the machine and the mask; it wears out and should be replaced on a regular schedule.
The removable water tank of a CPAP humidifier; it wears and needs replacing, especially if it cracks, clouds or leaks.
A soft strap that supports the jaw to help keep the mouth closed, used mainly with nasal and nasal pillow masks to reduce mouth leaks.
A fabric sleeve that slips over CPAP tubing to insulate it, reduce condensation and make the hose feel softer against your skin.
A cord or converter that runs a CPAP from a 12 V or 24 V DC source, such as a car outlet, RV or deep cycle …
A battery pack that runs a CPAP machine without mains power, for camping, power outages or long flights.
Plain, mild dish soap is the cleaning agent most CPAP makers and the FDA point to for masks, tubing and humidifier chambers.
