Oxygen machines, also known as oxygen concentrators, are devices that take in air and produce a gas with a significantly higher concentration of oxygen. They are used to provide oxygen therapy.FunctionOxygen machines work by compressing air and pushing it through molecular filters. These filters let oxygen through more easily than nitrogen, producing a gas with a higher concentration of oxygen.
SafetyBecause oxygen can be explosive, tanks of oxygen pose a hazard. Oxygen machines do not store concentrated oxygen and do not pose this risk.
PortabilityWhile tanks of oxygen can be very heavy, oxygen concentrators can be made fairly small, allowing them to be easily moved to where they are needed.
AccessibilityOxygen machines are relatively easy to operate. Someone who needs oxygen therapy can keep one at their home and administer treatment without having to go to a hospital.
Oxygen TherapyOxygen therapy is used in the treatment of a variety of conditions, particularly those that damage the lungs. Oxygen treatment is also used to stabilize a patient after a severe injury.
