The oxygen concentrator uses this air and then exhausts it in the form of 90% to 95% pure oxygen and 5% to 10% nitrogen. Separate the nitrogen to give the patient the maximum amount of oxygen, because, without the help of medical equipment, it is difficult to obtain this percentage of oxygen.
As with larger fixtures, these smaller portable nebulizers only have a nebulizers solution mixer and a suction nozzle connected to a hose, which is connected to a portable machine, so that the spray can be effectively delivered as needed.
