1. A respiratory device comprising:
an oxygen generator having:
a first inlet to ambient air,
one of a vacuum swing oxygen generating system and a pressure swing oxygen generating system in fluid communication with said first inlet and thereby disposed to draw ambient air and extract oxygen from the ambient air,
a first fluid pathway in fluid communication with said one of said vacuum swing oxygen generating system and said pressure swing oxygen generating system and thereby disposed to collect the extracted oxygen, and
a first outlet in fluid communication with said first fluid pathway and thereby disposed to dispense the extracted oxygen to a user; and
a ventilator having:
a second inlet to ambient air,
a blower in fluid communication with said second inlet and thereby disposed to draw ambient air,
a third inlet in fluid communication with said first fluid pathway upstream of said first outlet, wherein said blower is also in fluid communication with said third inlet and thereby disposed to draw at least some of the extracted oxygen, and
a second outlet in fluid communication with said blower and thereby disposed to dispense a mixture of the ambient air and the extracted oxygen to the user.
