DreamStation Auto CPAP data in Apnealytics

Supported. The original Philips Respironics DreamStation Auto CPAP writes its data to an SD card in Philips' proprietary P-Series format, and Apnealytics reads it alongside the DreamStation 2. This page covers what the machine records, where the card lives, how to import it, and what Apnealytics shows for DreamStation Auto CPAP data.

DreamStation Auto CPAP at a glance

In June 2021 Philips announced a voluntary recall of certain DreamStation and System One devices over sound-abatement foam. Many units were repaired or replaced; some owners moved to the DreamStation 2 or to another brand. Apnealytics has no part in that programme and makes no safety claims; we mention it only because it affects which machine many former DreamStation users have today. Check your serial number with Philips if you are unsure.

A note on the 2021 recall

Where the SD card is

The slot is on the side of the main unit, not the humidifier. Turn the machine off, wait for the screen to settle and press the card to release it. Keep a card in at all times: like every machine here, the DreamStation records detailed data only to the card.

Turn the DreamStation off and remove the SD card.
Insert the card into a reader on your computer
Card import is web-only.
Sign in at my.apnealytics.com and open Import.
Drag the whole card folder, P-Series and all, onto the drop zone
Files travel direct to private storage on Cloudflare R2, resumable.
Nights are parsed and deduplicated against anything already in your account.

If the parser improves later, Re-process in your import history updates past nights without a second upload.

Import in five steps

What you'll see

Nightly AHI and Philips event types
The DreamStation records obstructive apneas, clear-airway apneas, hypopneas, RERAs, flow limitation, periodic breathing and vibratory snore. These map into Apnealytics' obstructive, central, hypopnea and unclassified composition, with the Philips-specific flags in the event strip.
Pressure and Flex
Auto-CPAP nights show the 90th-percentile pressure against the set minimum and maximum, with the Flex level alongside.
Leak and Mask Analytics
Philips reports total leak rather than unintentional leak. Apnealytics labels it as such and Mask Analytics compares it per mask. On Pro, the waveform viewer reads the high-resolution.005 files for airflow and pressure.

Known quirks

Undocumented format. Philips has never published the P-Series layout. Everything known about it comes from community work, and our parser is tested against cards contributed by users.
Humidifier and tube data. The DreamStation records humidifier and heated-tube settings in the summary. These show in "What changed?" as with ResMed.
Firmware variations. Later DreamStation firmware added fields that early firmware lacks. The parser handles both.
Clock and daylight saving. The DreamStation's handling of clock changes can produce a night that appears split or doubled in community tools. We dedup these on import.

FAQ

Questions people ask

Help center →

Is the original Philips DreamStation supported by Apnealytics?

Yes. The original DreamStation 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.

What files does the DreamStation write to its SD card?

A P-Series folder containing a sub-folder named after the device serial, holding numbered binary files: a summary file, an events file and high-resolution waveform files. They are not EDF, so Philips needed its own parser.

Can Apnealytics read DreamMapper?

No. DreamMapper is Philips' free app, reads only Philips machines, and has no export. Apnealytics reads the SD card directly, which holds far more than the app shows, including the waveform files for the Pro viewer.

I switched from a DreamStation to a ResMed after the recall. Can I keep my old data?

Yes. Keep your old DreamStation cards and upload them. The Pro plan supports multiple machines with full gear history, so your DreamStation nights and your ResMed nights will sit on one timeline with the switch marked in "What changed?".

What else reads DreamStation data?

OSCAR, the free open-source desktop program for Windows, Mac and Linux, reads Philips machines. SleepHQ lists Philips among its supported brands. DreamMapper shows a daily summary. Apnealytics reads it too.
