ResMed's CPAP masks with magnets have an urgent field safety notice due to potential interference with certain medical devices or implants.

The company says in the notice that it is updating the contraindications and warnings in its user guides to instruct patients on the safe use of masks with magnets “in response to new information from latest industry practices and global safety data.”

Magnets are used in some ResMed masks to provide a simple and easy way for patients to attach and detach the headgear to the mask frame when regularly fitting the mask for use. This can be notably beneficial to patients with disabilities, including those facing dexterity or vision impairment.
