This is the standard Breathe-O-Prene Headgear that comes with all ResMed Pixi CPAP/BiLevel Masks. The headgear is designed specifically for children aged 2 and up. There are three points of adjustment on the headgear straps -- at the top, side and bottom -- providing a wide range of adjustments to cater to children of various ages. The headgear is designed to sit away from the childs eyes and ears to reduce irritation and obstruction and provide a clear line of site for both children and caregivers. Pixi headgear is designed to be adjusted primarily by an adult or caregiver. Adjustment points are kept out of view of the child to minimize tampering. Both a quick-release latch and an emergency latch are included on the headgear to ensure that the headgear can be quickly and easily should the need arise.
