Philips System One 60 Series
Read your System One SD card
CPAP Clarity opens the card from your Philips System One 60 Series and shows what it has been quietly recording, often for years: every scored event with its time, the pressure the machine delivered, your mask leak, and the breath-by-breath flow waveform. It runs in your browser and nothing is uploaded.
Philips' 2021 recall notice lists SystemOne (Q series) devices among the affected CPAP machines; whether yours is affected depends on its model and serial number. This page is for reading the data a machine you already own has recorded. Philips recall and remediation information is the place to check your own device, alongside the clinician who manages your therapy.
What CPAP Clarity shows you
Obstructive apneas, clear-airway (central) apneas, hypopneas and RERAs, each on your timeline at the time the machine scored it, rather than one nightly figure.
The airflow trace the machine scores events from, charted on the same clock as your events. On the card we validated, 5,362 of its 6,234 sessions (86%) carried a waveform, across all its years rather than just recent weeks.
The pressure the machine actually delivered every couple of minutes, which sits a little under a fixed prescription when C-Flex or C-Flex+ is on. On a REMstar Auto it shows where the machine settled and how high it reached.
Total leak minus the air your mask is designed to vent at that pressure, the way OSCAR reports it. What is left is the part that escaped your seal.
A System One card often holds years of therapy. CPAP Clarity reads all of it, including the Clear0 and Clear1 folders that hold sessions from before the card was cleared. A session written in more than one folder is read once.
Mode, pressure, ramp time and starting pressure, C-Flex or C-Flex+ and its level, and humidifier level, read from the card itself.
Nightly usage hours and the four-hours-on-70%-of-nights view the usual adherence rule is measured against.
Cross-checked against OSCAR on a real REMstar Pro 460P card: usage on all 2,578 nights, and obstructive, central and hypopnea counts on the 2,310 nights that recorded events, with zero nights out of tolerance. The AHI matches OSCAR on all but two of those nights; on those two, part of the night had no event record, so CPAP Clarity scores the AHI over the recorded hours where OSCAR uses the whole night. Average and 95th-percentile pressure matched within the device's 0.1 cmH2O step, and the flow waveform matched sample for sample on the six full nights we exported.
How to import your data
Remove the SD card
Turn the System One off and unplug it so the last session finishes writing. The card slot is on the side of the machine. Press the card in gently, let it spring out, and pull it free.
Insert into your computer or phone
Use a laptop card slot, an inexpensive USB SD reader, or a USB-C or Lightning reader on a phone. A card with years on it can be a few hundred megabytes, so a computer is the comfortable choice for a first import.
Drop the whole card on CPAP Clarity
Open CPAP Clarity, go to the import page, and select the entire card or its P-Series folder. Everything is read in your browser; nothing is uploaded.
Frequently Asked Questions
Does CPAP Clarity work with my System One?
Yes, for the System One 60 Series: model numbers whose middle digit is a 6, such as the REMstar Pro 460P and REMstar Auto 560P. The REMstar Pro 460P has been checked against OSCAR on a real card across 2,578 nights. The REMstar Auto reads through the same decoder but has not been cross-checked on a real card yet. BiPAP Pro and BiPAP Auto 60 Series cards (660P, 760P) import usage and events, but leak is not measured on them yet and they have not been checked either. The older 50 Series (450P, 550P and similar) is not supported yet.
How do I tell a 60 Series from a 50 Series?
Look at the model number on the label under the machine. A 6 in the middle (460P, 560P) is the 60 Series, which CPAP Clarity reads. A 5 in the middle (450P, 550P) is the older 50 Series, which uses an earlier card format. If you drop a 50 Series card, CPAP Clarity tells you it cannot read it yet rather than showing wrong numbers.
What about the 2021 Philips recall?
Philips' 2021 recall notice lists SystemOne (Q series) devices among the affected CPAP machines. Whether your own machine is affected depends on its model and serial number, which Philips' recall page lets you check. This page is only for reading the data a machine you already own has recorded; whether to keep, remediate or replace it is a conversation with the clinician who manages your therapy. CPAP Clarity does not sell devices and earns nothing from what you decide.
Which folder do I select?
Select the whole card, or the P-Series folder on it. Do not go one level deeper into the folder named after your serial number, because CPAP Clarity recognizes a Philips card by seeing P-Series in the path.
What are the Clear0 and Clear1 folders?
A card gains them when it is cleared, for example with Philips' Encore software at a provider's office. They hold sessions from before the clear. CPAP Clarity reads them with the rest of the card, and a session that appears in more than one folder is read once.
Why do some old nights show no pressure?
On some nights the machine kept only a summary, without the readings or events it records during the night. CPAP Clarity shows those nights with their usage, and marks their AHI and pressure as not recorded rather than guessing them. On the validated card that was 268 of 2,578 nights, recent ones among them.
Is my data safe?
All processing happens in your browser. Your CPAP data never leaves your computer and is never uploaded to any server. CPAP Clarity stores your data in your browser's local storage so you can return to it later without re-importing.
