Mask for noninvasive ventilator

At home, I use a non-invasive ventilator at night and my pulmonologist just increased the pressures and if I have a high pressure, the leaks start. So I need to switch to a better mask. The problem is some of these that are set up for non-invasive ventilation don’t have the right port in case of a power outage so i can breathe on room air. Any thoughts?

I know that all of Resmed's full face CPAP masks have an Anti-Asphyxia Valve (AAV), including the Quattro FX and AirFit F20 you mentioned. So basically any Resmed PAP therapy mask with "F" model designation. (source)

I'm pretty sure, but not 100% certain, that most of the other PAP mask manufacturers have a similar anti-asphyxia safety feature built into in their full face masks too. Otherwise we'd all be talking about the potential danger of using them... which we aren't.

Why don't you share the specific machine.

• The mask you have
• The masks that have the right port
• Why you need such a port.
