Philips AF541 NIV Face Masks with EE Leak 1 Elbow, 4-Point Headgear, and Over the Nose Cushion

Manufacturer: Philips Healthcare

Designed to rest comfortably on the face, the AF541 noninvasive ventilation (NIV) mask features interchangeable over-the-nose (OTN) cushions to achieve the benefits of mask rotation while using a single mask.


Mask rotation helps to decrease skin breakdown by varying the pressure points on the skin. Alternating the cushions on the Philips Respironics AF541 mask offloads pressure points on the skin to better support your mask rotation strategies. By replacing just the cushion instead of the entire mask style, it is also a cost-effective strategy that enhances your workflow.
