Please be aware that ResMed have recently sent out an Urgent Field Safety Notice regarding several of their masks. We are writing to you to make you aware of the information contained in their letter and the instructions you should follow if you are impacted by this issue.
ResMed has provided us with important information regarding their masks with magnets which may interact with some implants or certain medical devices. These masks are used to deliver air to a patient from a positive airway pressure (PAP) device.
Magnets are used in some ResMed masks that provide a simple and easy way for patients to attach and detach the headgear to the mask frame as detailed in the picture below.
Resmed is updating its contraindications and warnings to further inform patients and healthcare professionals on the safe use of ResMed masks with magnets.
Does this apply to me?
If you do not use a mask with magnets, the updated contraindications and warnings do not apply to you.
The updated contraindications for ResMed masks with magnets only apply if you, or anyone in close physical contact with you while using the mask (e.g., bed partner), has a certain implant or medical device that is identified below.
If you use a ResMed mask with magnets, you should also be aware of the updated warning noted below.
Masks with magnetic components are contraindicated for use by patients where they, or anyone in close physical contact while using the mask, have the following:
- Active medical implants that interact with magnets (i.e., pacemakers, implantable cardioverter defibrillators (ICD), neurostimulators, cerebrospinal fluid (CSF) shunts, insulin/infusion pumps)
- Metallic implants/objects containing ferromagnetic material (i.e., aneurysm clips/flow disruption devices, embolic coils, stents, valves, electrodes, implants to restore hearing or balance with implanted magnets, ocular implants, metallic splinters in the eye)
Keep the mask magnets at a safe distance of at least 6 inches (150mm) away from implants or medical devices that may be adversely affected by magnetic interference. This warning applies to you or anyone in close physical contact with your mask. The magnets are in the frame and lower headgear clips, with a magnetic field strength of up to 400mT. When worn, they connect to secure the mask but may inadvertently detach while asleep.
Implants/medical devices, including those listed within contraindications, may be adversely affected if they change function under external magnetic fields or contain ferromagnetic materials that attract/repel to magnetic fields (some metallic implants, e.g., contact lenses with metal, dental implants, metallic cranial plates, screws, burr hole covers, and bone substitute devices). Consult your physician and manufacturer of your implant/other medical device for information on the potential adverse effects of magnetic fields.
