Extra Port in Z1 Auto
What is the small extra port next to the main output port on my HDM Z1 Auto APAP machine? The tube adapter plugs into it, but seemingly for no reason. Is the small port for supplemental oxygen input, or does it lead to some kind of sensor? I am unable to attach a picture of it, but it is the mystery hole next to the main output port.
