Philips DreamStation 2 Auto CPAP Advanced
How to set up the Philips DreamStation 2 Auto CPAP Advanced
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.
Pick the right spot
Put the machine on a firm, flat surface within easy reach, lower than your sleeping position, and away from heaters, radiators and air vents.
Do not set it directly on carpet, bedding, fabric or anything that can burn, and keep the air inlet on the side clear of curtains and blankets. The FDA repeated this advice in its 2023 DreamStation 2 overheating notice.
Remove film and wash the tank
Peel off all protective film. Philips says to clean the humidifier water tank before first use, so wash the lid, base and seal in warm water with a little mild dish soap, rinse well and let them air dry.
Check the filters
Take the water tank out to reach the filter area. The grey reusable pollen filter must be in place whenever the machine runs. If you have a blue disposable ultra-fine filter, snap the grey filter on top of it with the arrows lined up, then slide the pair into the device.
Fill the water tank
With the tank off the machine and sitting flat, fill it with room temperature distilled water no higher than the maximum fill lines. Do not add anything to the water.
Hook the lid over the small tabs, press it down until it snaps, then slide the tank back into the machine until it latches. Never fill the tank while it is attached.
Connect power
Make sure the tank is empty or properly seated, then plug the power supply cord into the bottom of the machine, the AC cord into the power supply, and the plug into a wall outlet that is not controlled by a switch. Do not use an extension cord. A white ring around the therapy button means it has power.
Attach the tubing and mask
For heated tubing, line up the pin connectors with the bottom of the air outlet and push until the side clips click. Standard tubing simply slides on. If you use 12 mm tubing, fit the supplied mask adapter on the mask end.
Connect the mask and headgear following the mask's own instructions.
Set language and time
The first time it starts, the machine may ask you to choose a language and set the time. You can change both later under Device settings.
Start your first night
Put your mask on, then press the therapy button on top. The ring turns blue when therapy is running. A small amount of leak is normal; adjust the headgear if air blows into your eyes or the leak is loud.
If your provider enabled Auto On, the airflow starts by itself when you breathe into the mask.
Run a mask fit check
With therapy off, the Last Session screen shows Good fit or Adjust fit. Tap it, put your mask on and tap Start to run a mask fit check before bed if the seal feels off.
After setup: settings worth knowing
- Ramp Plus: Holds a lower starting pressure while you fall asleep, then moves to your prescribed pressure. It can raise pressure earlier if it detects breathing events.
- Humidity: Sets how much the heater plate warms the water. Higher numbers add more moisture.
- Heated tube temperature: Warms the heated tube to cut down on condensation (rainout) in the hose and mask.
- Flex: Lowers pressure slightly as you breathe out so exhaling feels easier. Level 1 gives a little relief, 2 and 3 give more.
- Mask fit check: Runs a short test to tell you whether your mask leak is low enough for the machine to work well.
- Auto On and Auto Off: Starts airflow when you breathe into the mask and stops it after you take the mask off.
- Airplane mode: Turns off the wireless radios. It switches itself back off after three days.
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 removable water tank of a CPAP humidifier; it wears and needs replacing, especially if it cracks, clouds or leaks.
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 padded bag that protects the machine, mask, tubing and power supply in transit.
A long, flexible brush sized to reach the full length of CPAP tubing so you can scrub the inside, not just soak it.
Plain, mild dish soap is the cleaning agent most CPAP makers and the FDA point to for masks, tubing and humidifier chambers.
