Questions and answers

General (6)

What is the issue?

The foam that is used in some devices to reduce sound and vibration showed signs of degradation (damage) and chemical emissions. This is a potential risk to health. After careful analysis, we issued a Recall Notification in the US and a Field Safety Notice in other markets.
We are aware of the concerns raised by this information and we are sincerely apologetic for any disruption of care or inconvenience that may have been a result. Please be assured that we are doing all we can to resolve the issue as quickly as possible. We thank you for your patience as we work to restore your trust.

What is the advice for patients and customers?

If you have not done so already, please click here to begin the device registration process.
Our update in November 2021 provides broadened guidance regarding affected CPAP, BiLevel PAP and Mechanical Ventilator devices, and mechanical ventilators, as follows:

For patients using BiLevel PAP and CPAP devices, talk to a health care provider to decide on a suitable treatment for medical conditions, which may include:
Stopping use of an affected device
Using another similar device that is not part of the recall
Continuing to use an affected device, if a patient’s health care provider determines that the benefits outweigh the risks identified in the recall notification.
Using alternative treatments for sleep apnea.

For patients using life-sustaining mechanical ventilator devices, they should not stop or change ventilator use until they have talked to their health care providers regarding factors including:
Whether in the judgement of the treating clinical team the benefit of continued usage of these ventilator devices may outweigh the potential risks identified in the recall notification.
Consultation with health care providers about using an inline bacterial filter with ventilators, which may help to filter out particles of foam, as indicated in the Philips recall notification, which also notes limitations of this option and areas of caution.
We strongly recommend that customers and patients do not use ozone-related cleaning products. Additionally, we remind both customers and patients to review the age of their BiLevel PAP and CPAP devices, as they are recommended to be replaced after five years of use.
Please be assured that we are treating this matter extremely seriously, and are working to address this issue as efficiently and thoroughly as possible.
We have developed a comprehensive plan to replace the current sound abatement foam with a new material that is not affected by this issue and have already begun this process.
For more information on the recall notification (U.S. only) / field safety notice (Outside of U.S.), as well as instructions for customers, users and clinicians, affected parties may contact their local Philips representative or visit www.philips.com/SRC-update
If you are a patient who has been affected by this recall, do not try to remove the foam from your device. Doing this could affect the prescribed therapy and may void the warranty. We have trained service professionals on hand who can make sure that the affected foam is completely removed, safely, and that the new silicone foam is inserted correctly.

Which devices are affected?

The issue relates to certain ventilators, Philips CPAP (Continuous Positive Airway Pressure) and BiPap (Bi-Level Positive Airway Pressure) sleep apnea devices.
The affected products are identified in the tables below:

What products are not affected and why?

Products that are not affected may have different sound abatement foam material, as new materials and technologies have become available over time. Also, sound abatement foam in unaffected devices may be placed in a different location due to device design. You can find the list of products that are not affected here.

Are there any recall updates regarding patient safety?

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.

Review of this assessment has determined that exposure to the level of VOCs identified to date for the first-generation DreamStation devices is not typically anticipated to result in long-term health consequences for patients. This new assessment is limited to the evaluation of VOCs for first-generation DreamStation devices and does not evaluate the risks of potential foam particulates or cover other devices affected by the recall. It is important to note that the tested DreamStation devices were not exposed to ozone cleaning. Further testing and analysis is ongoing.

What devices have you already begun to repair/replace?

In most markets, devices currently authorized for repair and replacement include DreamStation CPAP and Bi-level devices, DreamStation ASV devices, and DreamStation ST/AVAPS devices.
With regard to mechanical ventilators, Philips is deploying a permanent corrective action to address the issues described in the recall notification. As part of the remediation process, customers and patients will be provided with more information on the next steps to implement the permanent solution as it becomes available.

In the interim, in specific markets, a Trilogy Evo device can be made available for patients currently using affected Trilogy 100 and 200 devices. Please contact your Philips representative if you are in need of a loaner Trilogy Evo device for a patient. Please note that once an RP kit is shipped for the affected Trilogy 100/200 device, the loaner Trilogy Evo must be returned within 45 days to avoid being charged.

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 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 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 authorized 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 recall, 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 color 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.
U.S. only: If you are looking for more information on how to use your new device and become familiar with it, you can visit www.philips.com/ds2-replacement for more information.

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?

We expect that we will have completed the repair and replacement program by approximately the end of 2022 for the vast majority of patients.

We understand that this is frustrating and concerning for patients. 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?

Preventive maintenance for Trilogy has been paused until the new silicone foam is authorized and available.

The Trilogy, as well as the components containing PE-PUR foam, have all been placed on hold, for potential risks as outlined in the sound abatement foam recall 1) PE-PUR foam may degrade into particles which may enter the device’s air pathway and be ingested or inhaled by the user, and 2) the PE-PUR foam may off-gas certain chemicals.

Trilogy service instructions require PM periods as outlined for the 24 months/10,000 blower hours as well as the blower replacement. During these preventative maintenance periods, the service requires replacement of the PE-PUR foam components. Therefore, PM service cannot be completed until we have authorization for the new foam design with Trilogy.

In the interim, in specific markets, a Trilogy Evo device can be made available for patients currently using affected Trilogy 100 and 200 devices. Please contact your Philips rep if you are in need of a loaner Trilogy Evo device for a patient. Please note that once an RP kit is shipped for the affected Trilogy 100/200 device, the loaner Trilogy Evo must be returned within 45 days to avoid being charged.

Further testing and analysis is ongoing Please note that it is important that you only use approved cleaning methods for our devices and masks, as unapproved cleaning methods such as ozone may contribute to foam degradation.

What is the risk for patients?

Examples of potential risks include exposure to degraded sound abatement foam particles or exposure to chemical emissions from the sound abatement form material.

Our quality management system processes and analyis of user reports have indicated that this material may lead to patient harm and impact clinical care.

While there have been limited reports of headache, upper airway irritation, cough, chest pressure and sinus infection that may have been associated with the foam, based on lab testing and evaluations, it may be possible that these potential health risks could result in a wide range of potential patient impact. These could include transient potential injuries, symptoms and complications, as well as possibly serious injury which can be life-threatening or cause permanent impairment, or require medical intervention to preclude permanent impairment.

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.
