OSCAR, the Open Source CPAP Analysis Reporter

OSCAR News

This is a major release of OSCAR and the first to support the Philips Respironics DreamStation 2. We do recommend upgrading to this version.

The significance of this release is that the OSCAR Development team has resolved the encryption placed on the detailed data by Philips Respironics on the DreamStation 2 CPAP machines. This enables you, the end user, to directly read and act on this data.

OSCAR has no issues with data being encrypted, but the key should be readily and freely available to the CPAP user. It is not with the DreamStation 2.

OSCAR is an acronym that stands for, Open Source CPAP Analysis Reporter. OSCAR provides for the viewing of the high-resolution sleep data that is generated by the CPAP and stored on the SD card. OSCAR converts this data to graph form allowing the user to view this data down to a breath by breath level. OSCAR is free to use and is compiled in formats that will operate on Mac, Linux, and Windows. OSCAR can be downloaded from https://www.sleepfiles.com/OSCAR/. It is this information that enables you to provide data for discussion with your doctor and/or to view and optimize your personal therapy.

OSCAR is also used by many physicians and therapists who consult with patients, and by medical researchers comparing patient/machine responses across multiple platforms. OSCAR provides visual and statistical data details and enables comparisons across machine types and manufacturers, that are not available from proprietary manufacturer software and data products. Professionals who rely on OSCAR to provide research and to serve patient needs will lose this valuable resource if data becomes inaccessible, or only available through the manufacturer's data products.

Encryption and access to your own data

The changes made by Philips in the DreamStation 2 are harmful to patient empowerment, making it more difficult for you to manage your own sleep apnea therapy.

So far the OSCAR Team has found three major changes made by Philips in the DreamStation 2 devices:

  1. The data on the SD card IS Encrypted purportedly to limit access to the data to clinical personnel ONLY and NOT to the end-users, the people who have Sleep Apnea. As of June 2022, OSCAR can read this data.
  2. There are two levels of the DreamStation 2. First are the "Advanced" models. These are much more "user friendly" than the "NON-ADVANCED" models. The NON-ADVANCED models can easily be identified via their two-toned cases with blue bottoms. These "NON-ADVANCED" models truly limit what you can adjust.
  3. The tube temperature of some DreamStation 2 "NON-ADVANCED" models CANNOT be changed by the end-user. Why? When asked, a Phillips representative stated, "We are taking away more settings from the user in order to have the 'clinicians' take care of that". To our current knowledge, the DreamStation 2 CPAP and DreamStation 2 Auto CPAP (NON-ADVANCED models) do not have a Providers Menu. Changes to most CPAP settings can only be set via Care Orchestrator Essence, which is not available to the CPAP user.

The above changes are at best disturbing. The "official" read access to CPAP data for end users is via DreamMapper, which has Summary data and Compliance info only. Detail data is available only through Care Orchestrator Essence, which is available only to clinical personnel.

Item #1 speaks for itself. All detailed data is encrypted and as such is not available to the end-user from Phillips Respironics. (As noted above, OSCAR can currently access this information).

Item #3 outright says that Philips is taking away access to even basic humidification from the end-users.

Risks:

This is a big one. This trend within Philips Respironics to make all new devices so that ONLY clinical personnel will have access to your medical data is growing.

Philips Respironics has chosen to make some new devices so that ONLY clinical personnel will be able to change settings on the CPAP with access solely through Care Orchestrator, eliminating the Provider Menu. That appears to have been done on the DreamStation 2 (NOT ADVANCED) devices.

Philips Respironics could conceivably change the encryption at any time on all DreamStation 2 devices.
