If my device is affected, what do I do?

We understand that the situation may cause you some anxiety and you may feel uncertain about what to do next. Please be assured that our teams are working on a comprehensive remediation program to support patients with an affected device.

What is the potential safety issue with the device?

The potential issue is with the foam in the device that is used to reduce sound and vibration. In some cases, this foam showed signs of degradation (damage) and chemical emissions. This is a potential risk to health.

The initial concern with the foam related to possible emission of particulates (tiny particles) from degraded foam and certain chemicals of concern, called volatile organic compounds (VOCs). As a result, testing and assessments have been carried out.

Based on the comprehensive testing and analysis that we have done over the past 18 months – working with five independent certified laboratories, third-party experts and physicians - we now have a complete set of results for the first-generation DreamStation devices. Please click here for the latest testing and research information.

Further testing and analysis on other devices is ongoing.

Can I trust the new foam? How are you removing the old foam safely?

We know how important it is to feel confident that your therapy device is safe to use. While affected devices contained a polyester-based polyurethane (PE-PUR) sound abatement foam component, the sound abatement foam in all new and remediated devices is a silicone foam^*. When we refurbish the affected devices with a new blower and air pathway, we also clean and disinfect them.
This foam is cleared for use by the FDA in the DreamStation 2 CPAP device and authorised as part of our remediation.
When we refurbish the affected devices with a new blower and air pathway, we also clean and disinfect them. Our trained service professionals can make sure that the affected foam is completely and safely removed, and that the new silicone foam is inserted correctly.
If you are a patient who has been affected by this field safety notice, please do not try to remove the foam from your device. This could affect the prescribed therapy and may void the warranty.

^*Trilogy Evo devices provided as loaners do not contain the silicone foam or the affected PE-PUR foam.

I sent in my DreamStation CPAP device and received a DreamStation 2 CPAP Advanced and I would prefer to have my own device back

We understand that any change to your therapy device can feel significant. If you are used to using a DreamStation CPAP device and have received a new DreamStation 2 CPAP Adanced, this new device has also been set to the same prescription settings as before and is ready for use.
The DreamStation 2 CPAP Advanced is designed to provide a simplified user experience, including a premium colour touchscreen with fewer panes to navigate. Both the DreamStation CPAP and DreamStation 2 CPAP Advanced include an identifiable Therapy ON button. Unlike the DreamStation CPAP device, the DreamStation 2 CPAP Advanced device features the Ramp Plus feature where a user can select a comfortable start pressure. Once set, the device will automatically start at the selected Ramp Plus pressure with all future therapy sessions. A patient no longer needs to tap a Ramp button every night to start at the desired pressure. This means you can set the Ramp Plus presusre once and there is no need to restart it each night. Even Auto ON is enabled so that all you have to do is put your mask on and start breathing.
As we have previously noted in connection with the return of your DreamStation device, we will not be returning DreamStation devices back to the original user. Please review the DreamStation 2 Setup and Use video for help on getting started.

Should I stop using my device?

It is important that you do not stop using your device without discussing with your doctor. Although you may feel anxious at the news of the recall, we encourage you to talk to your doctor about the right treatment for you.

How long will it take to fix the issue?

Please be sure to check philips.com/src-update for the latest information on remediation progress.

I have seen foam repair kits offered online at Amazon.com and elsewhere from third parties. Can I buy one and install it instead of returning my device?

No. These “repair kits” are not approved for use with Philips Respironics devices. They are not approved for use by the FDA. They are not manufactured by Philips Respironics or our partners, and may pose a health hazard if used.

We do not offer repair kits for sale, nor would we authorize third parties to do so.

Devices affected by the field safety notice must be serviced only by qualified technicians. They do not include user serviceable parts. Attempts to remove or change the sound abatement foam may render the device permanently inoperative and create health hazards.

Please continue to follow the field safety notice instructions you have received for affected Philips Respironics Sleep & Respiratory Care devices. The latest information regarding this action can be found at our publicly available web site: www.philips.com/src-update

What are you doing to resolve the issue?

We are producing and shipping similar CPAP, BiLevel PAP and Mechanical Ventilator platforms with a different design. While recalled devices contained a polyester-based polyurethane (PE-PUR) sound abatement foam component, the sound abatement foam in all new and remediated devices is a different, silicone foam.

Alongside this, we have expanded our pool of experts in the areas of treatment and components, including specialists in toxicology, biocompatability and chemistry. We also continue to partner with scientific and medical experts as part of our commitment to quality and patient safety.

The replacement device I’ve received has the same model number as my affected device. Is this replacement device affected by the recall too?

No- the replacement device you have received is not affected by the field safety notice, because the foam in the device has been replaced with a new type of foam. During the recertification process for replacement devices, we do not change the device serial number or model number.

For business customers (5)
For business customers (5)
What is the cause of the issue?

Based on our analysis, the root cause of this issue is related to the sound abatement foam, currently used to reduce noise and vibration in specific identified products of the Sleep & Respiratory Care portfolio.

How long will it take to fix the issue?

Please be assured that we are doing all we can to meet demand, including increasing the production of repair kits and replacement devices. We will share regular updates with all those who have registered a device.

Are you still taking new orders for affected products?

We are not taking new orders at this time, and we have stopped all new shipments temporarily, in order to support the field safety notice.

Are spare parts currently part of the ship hold?

Spare parts are not currently affected by the ship hold, though there may be some limited exceptions.

For example, spare parts that include the sound abatement foam are on hold.

When can Trilogy Preventative Maintenance be completed?

What is the potential safety issue with the device?

The potential issue is with the foam in the device that is used to reduce sound and vibration. In some cases, this foam showed signs of degradation (damage) and chemical emissions. This is a potential risk to health.

The initial concern with the foam related to possible emission of particulates (tiny particles) from degraded foam and certain chemicals of concern, called volatile organic compounds (VOCs). As a result, testing and assessments have been carried out.

Based on the comprehensive testing and analysis that we have done over the past 18 months – working with five independent certified laboratories, third-party experts and physicians - we now have a complete set of results for the first-generation DreamStation devices. Please click here for the latest testing and research information.

Further testing and analysis on other devices is ongoing.

What is the risk for patients?

At the time the field safety notice was issued, Philips Respironics relied on an initial, limited data set and toxicological risk assessment. Out of an abundance of caution, a reasonable worst-case scenario was considered. At the time, Philips Respironics could not exclude possible carcinogenic effects with the limited dataset that was available. Philips Respironics did not have conclusive data indicating that exposure to the particulates or emitted chemicals would lead to cancer.

Since then, together with five independent, certified testing laboratories in the US and Europe and other qualified third-party experts, Philips Respironics has been conducting a comprehensive test and research program on the PE-PUR foam to better assess and scope the potential patient health risks related to possible emission of particulates from degraded foam and volatile organic compounds. This also includes an in-depth review and re-assessment of data and toxicological risk-assessments prior to June 2021.

This Philips Respironics December 2022 update is intended to provide healthcare providers, patients, and other stakeholders with updated information on the testing results and third party confirmed conclusions to date on results and findings from testing PE-PUR foam used in recalled devices for VOCs, particulate matter (PM), and other testing such that healthcare providers have additional information to make informed decisions regarding the risk of continued use of recalled products.

What are you doing to fix the issue?

To resolve this situation as quickly as we can, we are doing the following:

Working to reach everyone affected so they understand the situation and know what they need to do, starting with the registration of the affected devices.

Frequently updating everyone on what they need to know and do, including updates on our improved processes.

Ramping up our manufacturing and service capacity to ensure we can repair and replace affected devices.

Are there any steps that customers, patients, and/or users should take regarding this issue?

Patients who are concerned should check to see if their device is affected. The list of affected devices can be found here.
