Overview of impacted masks
September 6, 2022
These masks may continue to be used according to the updated instructions and labeling if patients or people in close proximity to them do not have implanted metallic medical devices or metallic objects in the body
Pittsburgh, Pennsylvania – Royal Philips’ (NYSE: PHG; AEX: PHIA) subsidiary Philips Respironics is alerting users of certain CPAP or Bi-Level PAP therapy masks with magnetic headgear clips or straps that these devices should not be used by or near patients and their household members, caregivers and bed partners who have metallic implanted devices or metallic objects (such as metallic splinters) in the body. The magnetic headgear clips are used to attach the headgear straps to the masks, which is a method that is commonly used in the sleep therapy devices industry.
This is a voluntary notification to users of specific CPAP or Bi-Level PAP therapy masks containing such magnetic clips to inform them of the updated instructions and labeling. All users should read and follow Philips Respironics’ voluntarily updated warning and added contraindication described below. This represents a new and industry-leading practice.
Contraindication: Use of the mask is contraindicated for patients and their household members, caregivers and bed partners that may be in close vicinity to patients using the masks, that have implanted devices that may be affected by magnets, including but not limited to:
Implantable cardioverter defibrillators (ICD)
Magnetic metallic implants/electrodes/valves placed in upper limbs, torso, or higher (i.e., neck and head)
Cerebral spinal fluid (CSF) shunts (e.g., ventriculo peritoneal (VP) shunt)
Intracranial aneurysm intravascular flow disruption devices
Metallic cranial plates, screws, burr hole covers, and bone substitute devices
Metallic splinters in the eye
Ocular implants (e.g., glaucoma implants, retinal implants)
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
Metallic gastrointestinal clips
Metallic stents (e.g., aneurysm, coronary, tracheobronchial, biliary)
Implantable ports and pumps (e.g., insulin pumps)
Hypoglossal nerve stimulators
Devices labeled as MR (Magnetic Resonance) unsafe
Magnetic metallic implants not labeled for MR or not evaluated for safety in a magnetic field
Patients should stop using the affected mask if the implant/medical device is contraindicated against the mask magnets. Patients should consult their physician immediately to determine if another mask can be used for their therapy. In the interim, switch to a non-magnetic mask if available, for continued therapy. Patients should properly dispose of the mask that has magnets after an alternative is obtained.
These masks may continue to be used according to the updated instructions and labeling if patients or people in close proximity to them do not have implanted metallic medical devices or metallic objects in the body.
Warning: Magnets with a magnetic field strength of 400 mT are used in the mask. With the exception of the devices identified in the contraindication, ensure that the mask is kept at least 6 inches (approx. 15 cm) away from any other medical implants or medical devices that can be impacted by the magnetic fields to avoid possible effects from localized magnetic fields. This includes household members, caregivers, and bed partners that may be in close vicinity to patients that use the masks.

More than 17 million masks containing magnetic clips have been distributed by Philips Respironics to date. As of August 30, 2022, Philips Respironics has received 14 reports of patients suggesting that the mask magnets may have impacted their medical devices including pacemaker interference, pacemaker failure leading to replacement, need of shunt adjustment, resetting of automatic implantable cardioverter defibrillator (AICD), seizures, defibrillator shutting off periodically, arrhythmia, irregular blood pressure, change in heartbeats, and cognitive issues.
Patients with questions may contact Philips Respironics’ customer service at 1-800-345-6443, (Monday – Friday; 8:30 AM ET to 8:00 PM ET) for more information about non-magnetic mask options. Patients may also contact their Durable Medical Equipment (DME) provider, which supplied the masks affected by this notice.
Any adverse events experienced with the use of masks containing magnetic clips should be reported to the FDA’s MedWatch Program by phone at 1-800-FDA-1088, by fax at 1-800-FDA-0178, by mail at MedWatch, HF-2, FDA, 5600 Fishers Lane, Rockville, MD 20852-9787, or on the MedWatch Web site at www.fda.gov/medwatch.
