DreamStation 2 Auto CPAP data in Apnealytics

Supported. The Philips Respironics DreamStation 2 Auto CPAP writes its therapy record to an SD card in a proprietary Philips format, and Apnealytics reads it. This page tells you what the machine records, where the card is, how to import it, and what Apnealytics shows for DreamStation 2 data.

DreamStation 2 Auto CPAP at a glance

The DreamStation 2 replaced the original DreamStation with a smaller body, a colour touchscreen and a new data layout. The newer layout needed its own parser, separate from the original DreamStation.

Modes	CPAP, Auto-CPAP (with CPAP-Check on some configurations)
Comfort	Flex pressure relief (0–3), Ramp Plus
Humidifier	Integrated heated humidifier, heated tube optional
SD card	SD card, in a slot on the side

Where the SD card is

The card slot is on the side of the main unit. Turn the machine off and wait a few seconds before pressing the card to release it. Keep the card in and keep a spare: the DreamStation 2 stores detailed data only on the card, and nights recorded without one are gone.

Turn the DreamStation 2 off and remove the SD card.
Insert it into a reader on your computer
Card import is web-only, as with ResMed.
Sign in at my.apnealytics.com and open Import.
Drag the whole card folder onto the drop zone
The upload goes directly to private storage on Cloudflare R2 and resumes if interrupted.
Nights are parsed and deduplicated against anything already in your account.

If the parser improves later, use Re-process in your import history and the nights update without uploading again.

Import in five steps

What you'll see

Nightly AHI with Philips event types
The DreamStation 2 records obstructive apneas, central (clear airway) apneas, hypopneas, RERAs, flow limitation and periodic breathing. Apnealytics maps these into its event composition: obstructive, central, hypopnea and unclassified, with the Philips-specific flags shown in the event strip.
Pressure and Flex
Auto-CPAP nights show the 90th-percentile pressure Philips reports against the set range, with the Flex level alongside, in the same place EPR appears for ResMed users.
Leak and Mask Analytics
Philips reports leak differently from ResMed, as total leak rather than unintentional leak. Apnealytics labels the measure clearly and Mask Analytics compares it per mask. On Pro, the waveform viewer reads the high-resolution files for airflow and pressure.

Known quirks

Proprietary format. Philips does not publish its file format. Our parser is built and tested against real cards contributed by users, rather than a documented EDF file.
Two generations, two layouts. The original DreamStation and the DreamStation 2 store data differently. Each has its own parser.
Modem and DreamMapper. Like ResMed's modem, the Philips modem sends a summary to Philips' servers and DreamMapper. It is not open to third parties, so the card is the import path.
Leak definitions. Because Philips reports total leak, numbers are not directly comparable with a ResMed machine's leak P95. Apnealytics shows the measure by name rather than pretend they match.

Compatible masks

The DreamStation 2 uses a standard 22 mm tube connection and works with Philips, ResMed and Fisher & Paykel masks. Mask tracking in your gear works alongside your nightly data:

Nasal
DreamWear Nasal, AirFit N20
Full face
DreamWear Full Face, AirFit F20
Nasal pillows
DreamWear Gel Pillows, AirFit P10

Three cards with real mask cut-outs on teal blobs: Nasal (DreamWear Nasal · AirFit N20), shown DreamWear Nasal; Full face (DreamWear Full Face · AirFit F20), shown AirFit F30i; Nasal pillows (DreamWear Gel Pillows · AirFit P10), shown AirFit P30i; footer: standard 22 mm tube, mask tracking and reminders work today

Mask replacement reminders work now; seal and AHI per mask fill in from the nights you import.

FAQ

Questions people ask

Help center →

Does Apnealytics support the Philips DreamStation 2?

Yes. The DreamStation 2 is supported. Create a free account, add the machine to your gear and upload the SD card; if the parser improves, Re-process in your import history updates past nights.

Where is the SD card on the DreamStation 2?

On the side of the main unit. Turn the machine off, wait a few seconds and press the card to release it. Keep the card in the machine at all times, because detailed data is written only to the card and cannot be recovered later.

Can Apnealytics read DreamMapper or the Philips modem?

No. DreamMapper is Philips' own app, Philips-only, and it has no export. The modem reports to Philips' servers. Apnealytics reads the SD card directly, which holds more detail than DreamMapper shows, including the high-resolution files for waveforms.

Will my DreamStation 2 data look the same as ResMed data?

Mostly. AHI, usage, event types and pressure sit in the same places. Two differences are labelled: Philips reports a 90th-percentile pressure where ResMed reports a 95th, and Philips reports total leak rather than unintentional leak. Comparisons within one machine remain reliable.

What else reads DreamStation 2 data?

OSCAR, the free desktop program for Windows, Mac and Linux, reads Philips machines, and SleepHQ lists Philips among its supported brands. DreamMapper shows a daily summary. Apnealytics can import your historical cards in one go.
