To our CPAP Patients:

On Monday June 14, Philips Respironics issued a voluntary recall on nearly all of its CPAP and BiPAP machines- including Dreamstation1. A small percentage of machines have been confirmed to have a defect resulting in damage to an insulating foam within the blower unit. It appears that this has been found predominantly when such machines have been cleaned with ozone cleaning machine device.

The defective machines may emit small black particles that are pieces of foam, and these may be seen in your water chamber or tubing. Symptoms can include new development of headache, dizziness, sinus congestion, or chest pressure after usage of the device.

Many of you have received the notice from the manufacturer to discontinue use of the machine until contacting your physician. Our physicians have had many meetings with the manufacturer as well as with other sleep medicine practices, and we currently recommend the following:

• Call Philips Respironics at 1-877-907-7508 to register your device or register your device via the web at: https://www.philipssrcupdate.expertinquiry.com/
• Even if your device is indeed on the Philips Respironics recall list, we do NOT recommend discontinuing the use of your PAP therapy, but to contact Philips Respironics for follow up of repair or replacement of the device.
• If you suspect your machine is not simply on the recall list, but actually defective based upon black particles visible to the naked eye in your tubing or water chamber, you should contact your equipment company to see if more timely corrective measures can be offered, such as a new or borrowed machine.
• For machines that are either on recall or actually defective, the repair involves removing and replacing the foam that is embedded inside the machine. This can only be done by the manufacturer, not by your DME supplier.
• Finally, although we do not recommend discontinuing the use of your machine, we do recommend that all of our patients discontinue the use of ozone or UV cleaners until we have learned more about this. Just use soap and water or a vinegar solution for now.

Please understand that our office staff and physicians do not have any further information, or access to actual equipment. Please check with Philips Respironics and your DME company for further information.

We are looking forward for prompt intervention from the manufacturer to ensure that the device is repaired or replaced. We will be posting updates on this site as we receive them from the manufacturer.

Frequently asked questions

1. Why is Philips issuing a recall notification for certain CPAP, BiLevel PAP and mechanical ventilators?

• On April 26, 2021, Philips provided an important update regarding proactive efforts to address identified issues with a component in certain products of our Sleep and Respiratory Care portfolio.
• At that time, out of an abundance of caution and based on available information, Philips advised of potential health risks related to sound abatement foam used in specific Philips Continuous Positive Airway Pressure (CPAP), BiLevel Positive Airway Pressure (BiLevel PAP) devices, and Mechanical Ventilators. The company also indicated that analysis of potential health risks was ongoing, and that further information would be provided when available.
• As a result of extensive ongoing analysis following this announcement, on June 14, 2021, the company issued a recall notification for specific affected devices.
• The recall notification informs customers and users of potential impacts on patient health and clinical use related to this issue. Possible health risks include exposure to degraded sound abatement foam, for example caused by unapproved cleaning methods such as ozone, and exposure to chemical emissions from the foam material. High heat and high humidity environments may also contribute to foam degradation in certain regions.
• To date, Philips has received a limited number of reports of possible patient impact due to foam degradation, and no reports to date regarding patient impact related to chemical emissions. The company continues to monitor reports of potential safety issues as required by medical device regulations and laws in the markets in which we operate.
• The recall notification advises patients and customers to take the following actions:
  • For patients using BiLevel PAP and CPAP devices: Discontinue use of affected units and consult with physicians to determine the benefits of continuing therapy and potential risks.
  • For patients using life-sustaining mechanical ventilator devices: DO NOT discontinue or alter prescribed therapy, without consulting physicians to determine appropriate next steps.
• Philips is recommending that customers and patients halt use of ozone-related cleaning products, and adhere to their device Instructions for Use for approved cleaning methods.
• Additionally, Philips is reminding customers and patients to review the age of their BiLevel PAP and CPAP devices, as they are typically recommended to be replaced after five years of use.
• We are treating this matter with the highest possible seriousness, and are working to address this issue as efficiently and thoroughly as possible.
• The company has developed a comprehensive plan to replace the current sound abatement foam with a new material that is not affected by this issue, and has already begun this process.

11. What is the cause of this issue? Was it a design, manufacture, supplier or other problem?

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

12. How did this happen, and what is Philips doing to ensure it will not happen again?

• Philips has a robust Quality Management System and has followed our review and
  analysis processes to help identify and address this issue.
• The products were designed according to, and in compliance with, appropriate standards upon release. As new standards are developed, they require assessment of product characteristics according to quality and regulatory processes. Philips Quality Management System has been updated to reflect these new requirements.
• However, while standards have been updated, products developed on the prior standard are still in compliance with medical device regulations. The foam degradation and chemical emission issues were discovered as part of our Quality Management System processes, and are being corrected in accordance with appropriate regulatory requirements.
• Philips has been in full compliance with relevant standards upon product commercialization.

13. What is meant by “high heat and humidity” being one of the causes of this issue?

• Philips has determined that the foam may degrade under certain circumstances, influenced by factors including use of unapproved cleaning methods, such as ozone*, and certain environmental conditions involving high humidity and temperature.
• The environmental conditions that may be one of the causes of this issue refer to the
  climate and regional temperatures of the countries where the devices are used
  and stored.
• This factor does not refer to heat and humidity generated by the device for patient use.

14. Do affected units exhibit features that customers / users should watch out for? Particles or other visible issues?

• Users should consult with their physicians as directed in the recall notification.

15. Can Philips replace products under warranty or repair devices under warranty?

• Affected devices may be repaired under warranty.
• Philips will provide further information regarding warranty replacement procedures during this issue when it is available.

16. In those regions where Philips provides both patient care and devices, will new patients be set up with devices? Will existing patient devices that fail be replaced?

• At this time, Philips is unable to set up new patients on affected devices. Philips may
  work with new patients to provide potential alternate devices.
• Philips may repair / replace ventilator units that patients are reliant on in emergency
  situations such as device failure during required treatment, to ensure continuity of care.
• Philips CPAPs cannot be replaced during ship hold.

17. Is Philips certain that this issue is limited to the listed devices? Is there any possibility others are affected?

• Philips has completed our analysis in accordance with our Quality Management System and identified all affected products, which are included in our notifications to regulatory agencies and customers.
• No further products are affected by this issue.
