Abstract

A respiratory device can include an oxygen generator and a ventilator. The oxygen generator can include a first inlet to ambient air, a vacuum or pressure swing oxygen generating system in fluid communication with the first inlet, a first fluid pathway, and a first outlet. The ventilator can include a second inlet to ambient air and a blower in fluid communication with the second inlet to draw ambient air. The ventilator can include a third inlet in fluid communication with the first fluid pathway upstream of the first outlet. The blower can also be in fluid communication with the second inlet to draw at least some of the extracted oxygen. The ventilator can also include a second outlet in fluid communication with the blower to dispense a mixture of the ambient air and the extracted oxygen to the user.
