ResMed is giving more information about the safe use of their magnetic masks by updating existing guidelines. This comes as a response to new insights from post-market monitoring and industry practices concerning potential magnetic interference with specific medical devices. The update includes a stronger warning against using ResMed masks with magnets for individuals with: ​

1. Active medical implants sensitive to magnets (e.g., pacemakers, implantable cardioverter defibrillators, neurostimulators, cerebrospinal fluid shunts, insulin/infusion pumps). 
2. Metallic implants or objects containing ferromagnetic material (e.g., aneurysm clips, embolic coils, stents, valves, electrodes, implants for hearing or balance with magnets, ocular implants, metallic splinters in the eye). 
Recommended Course of Action For patients with contraindications using a ResMed mask equipped with magnets ​

If you, or someone in close physical proximity (such as a bed partner), possesses an active medical implant or metallic implanted object mentioned in the contraindications: ​
- Swiftly replace your magnet-containing mask with an alternative one that lacks magnets. 
- Reach out to your mask provider to explore other mask options. 

Note: ResMed is supplying your mask provider with magnet-free masks for replacement. ​
- In the absence of an alternative mask, seek guidance from your physician/doctor for the appropriate course of action regarding your therapy. 
- Dispose of the magnet-equipped mask once you obtain a replacement. 

Note: Not all models or variants of medical devices listed in the contraindications are susceptible to external magnetic fields. If uncertain about whether a medical device/implant falls under the contraindications or if you need additional information on the potential adverse effects of magnetic fields for your specific device, please consult your physician/doctor. ​

For all other patients using a ResMed mask with magnets

​If the use of a ResMed mask with magnets is not contraindicated for you, feel free to continue usage while adhering to all provided instructions, including those outlined in this letter. ​

It is crucial to maintain a minimum distance of 6 inches (150mm) between ResMed masks with magnets and any implants or medical devices susceptible to magnetic interference, as specified in the updated Warning ​

Philips Magnet Masks - Urgent Field Notice

Philips Magnet Masks - Urgent Field Notice The U.S. Food and Drug Administration (FDA) is alerting patients, caregivers, and health care providers that Philips Respironics (Philips) recalled certain masks used with bilevel positive airway pressure (also known as Bilevel PAP, BiPAP, or BPAP) machines and continuous 
positive airway pressure (CPAP) machines due to a serious safety concern. The recalled masks have magnets (placements shown by black circles in the picture below) and can cause potential injuries or death when use of a recalled mask with magnets interferes with certain implanted metallic medical devices and metallic objects in the body. ​

These potential adverse events can occur in people who use the masks, or in people near a person using the mask. Additionally, the recalled Philips masks may be used with other manufacturers’ BiPAP and CPAP machines. Users of any BiPAP or CPAP machine should check to see whether their mask is one of the recalled Philips masks. 
Device Description 

The recalled masks are worn by a patient when using a BiPAP or CPAP machine and have magnetic headgear clips to hold them in place. The recalled masks are for single patient use in the home or multi-patient use in the hospital or other clinical environments. The recalled masks are for patients weighing more than 66lbs (30kg), except for the Wisp Youth Nasal Mask and Therapy Mask 3100 NC/SP which are for patients seven years of age and older weighing more than 40lbs (18kg).

The Magnets in the Recalled Masks May Affect Certain Metallic Medical Devices or Metallic Objects in the Body Presenting a Potential Risk 

The recalled masks have magnets that can potentially cause injury or death if people who use them, or people near a person using a recalled mask, have certain implanted metallic medical devices or metallic objects in the body, such as: ​

- Pacemakers 
- Implantable cardioverter defibrillators 
- Metallic stents (such as aneurysm, coronary, tracheobronchial, and biliary) 
- Neurostimulators (such as hypoglossal nerve stimulators)
- Magnetic metallic implants, electrodes, and valves placed in upper limbs, torso, neck, or head Cerebral spinal fluid shunts (such as ventriculoperitoneal shunt)
- Aneurysm clips 
- Embolic coils
- Intracranial aneurysm intravascular flow disruption devices 
- Metallic cranial plates, screws, burr hole covers, and bone substitute devices 
- Ocular implants (such as glaucoma implants and retinal implants; intraocular lenses placed during cataract surgery are not impacted)
- Certain contact lenses with metal Implants to restore hearing or balance that have an implanted magnet (such as cochlear implants, implanted bone conduction hearing devices, and auditory brainstem implants) 
- Magnetic denture attachments
- Implantable ports and pumps (such as insulin pumps) 
- Metallic gastrointestinal clips 
- Certain metallic joint replacements 
- Devices labeled as Magnetic Resonance (MR) 
- Unsafe Magnetic metallic implants not labeled for MR or not evaluated for safety in a magnetic field 
- Metallic splinters in the eye 
- Metallic shrapnel in the body 

If the magnets affect the functioning or induce movement of certain implanted metallic medical devices or metallic objects in the body, the potential risks may include:
- For cerebral spinal fluid and ventriculoperitoneal shunts: potential increased pressure on the eye or brain, which may be fatal. 
- For aneurysm clips: disrupted suture lines or clip separation, which may be fatal. 
- For pacemakers: heart block or irregular heartbeat, which may be fatal. 
- For cardioverter defibrillators: may fail to shock, which may be fatal. 
- For neurostimulators: compression of the brain, seizures, or lead migration, which may be fatal. 

Medical Device Reports Manufacturers, such as Philips, are required to submit medical device reports (MDRs) when information reasonably suggests that their device may have caused or contributed to a death or serious injury, or has malfunctioned and that device or a similar device they manufacture would likely cause or contribute to a death or serious injury if the malfunction were to recur. Health professionals, consumers, and patients may voluntarily submit reports of device adverse events and malfunctions to the FDA. ​

As of August 30, 2022, Philips reported 14 serious injuries and 0 deaths related to the use of the recalled masks. The reported injuries included pacemaker failure leading to pacemaker replacement, a need for shunt adjustment, resetting of automatic implantable cardioverter defibrillator, arrhythmia, cognitive changes, headaches, change in heartrate (tachycardia, bradycardia), convulsions (seizures), and irregular blood pressure. ​

Although MDRs are a valuable source of information, this passive surveillance system has limitations. The incidence, prevalence, or cause of an event cannot typically be determined from this reporting system alone due to under-reporting of events, inaccuracies in reports, lack of verification that the device caused the reported event, and lack of information about details such as frequency of device use. Because of these limitations, MDRs comprise only one of the FDA’s several important postmarket surveillance data sources. These reports, along with data from other sources, can contribute important information to a medical device’s benefit-risk assessment. The FDA continues to review and assess the MDRs and will keep the public informed as new information becomes available. 

Recommendations for Patients and Caregivers 

- Stop use of the recalled mask and switch to a non-magnetic mask if available, if you or someone near you when using the recalled mask have any of the implanted metallic medical devices or metallic objects in the body listed above that may be affected by the magnets in the masks. 
- Ensure the recalled mask is kept at least 6 inches away from metallic medical implants, metallic objects in the body, and medical devices that can be impacted by the magnetic fields. 
- Consult with your health care provider to determine if another mask can be used for therapy and to decide if the plan for your care and treatment should change as a result of this safety issue. 
- Contact your health care provider immediately, if you experience any issues related to your medical device and report the issue through the FDA’s MedWatch Voluntary Reporting Form. 
- Contact Philips Respironics’ customer service at 1-800-345-6443 or visit their website at for more information about non-magnetic mask options.

Philips Respironics DreamStation 2 - Safety Notice

On November 28, the U.S. Food and Drug Administration (FDA) released a safety communication regarding possible thermal issues with the DreamStation 2 sleep therapy device while in use. 

There was not a sharp increase of reportable complaints. As part of our ongoing commitment to patient safety and quality, we conducted a retrospective review of possible DreamStation 2 thermal complaints initiated over the course of an almost three-year period since its launch in 2021. We filed approximately 270 reports with the FDA over the last three months as part of this post market surveillance. These reports were submitted in batches starting in August 2023, which we believe may have been interpreted incorrectly as a sharp increase in customer complaints. 

DreamStation 2 can continue to be used. As with any medical device, the instructions for use should be followed. 

Our number one priority continues to be patient safety and quality and we treat all feedback from our patients and our regulators with the highest levels of urgency. It is important to note: 

• Outside of continued adherence to the instructions for use, no additional action is needed by patients or DME/homecare providers as a result of the FDA’s publication. ​

• There is no product recall at this time.
