The oxygenator component serves as the lung and is designed to expose the blood to oxygen and remove carbon dioxide. ... Gas containing oxygen and medical air is delivered to the interface between the blood and the device, permitting the blood cells to absorb oxygen molecules directly.

How does an oxygen concentrator work?

An oxygen concentrator works by filtering and concentrating oxygen molecules from the ambient air to provide patients with 90% to 95% pure oxygen. The compressor of the oxygen concentrator sucks ambient air and adjusts the pressure at which it is provided. ... This forms a continuous loop that keeps producing pure oxygen.
