A portable oxygen concentrator is a medical device that can produce supplemental oxygen and is more mobile than the stationary oxygen equipment. It absorbs air from the environment, reduces nitrogen, and provides high concentration oxygen via a nasal cannula. When a health care provider prescribes supplemental oxygen, these devices can be helpful at home and while travelling.

The factors to consider when selecting a portable oxygen concentrator are oxygen needs, how oxygen is delivered, battery life, device weight, portability, charging, device output, warranty, and after-sale support. Some models do pulse-dose delivery, and others may have various settings based on the model.

An oxygen concentrator is a compact device that provides portable oxygen for the user, and should be chosen based on their prescribed oxygen requirements and used by following the instructions given by a healthcare professional. Regular cleaning, battery maintenance and battery care can help ensure reliable operation.

Depending on availability and needs, portable oxygen concentrators may be purchased or rented. Users can select a device that meets their oxygen therapy requirements by comparing specifications, service support, warranties, portability and total costs.
