A home oxygen concentrator draws in room air, separates much of the nitrogen and delivers oxygen-enriched gas for prescribed oxygen therapy. It is not a device for treating every cause of breathlessness, and the required flow and delivery mode must match the clinical prescription.
Stationary and portable systems serve different needs
Stationary concentrators are designed primarily for use at home with mains power. Wearable portable models emphasize mobility and often use pulse-dose delivery. Larger transportable units can have different capabilities. Compare the exact model rather than relying on a category label.
Continuous flow and pulse settings are different
Continuous flow is expressed in liters per minute. Pulse-dose delivery supplies oxygen when a breath is detected; a pulse setting number is not necessarily the same as that number in liters per minute. Suitability for rest, activity and sleep requires clinical guidance.
Choose around the prescribed use
Ask about the required delivery mode, flow, use during sleep, interface, approved tubing length, alarms and backup supply. Oxygen therapy may be prescribed when a person is not getting enough oxygen, but a diagnosis such as asthma or sleep apnea alone does not mean a concentrator is appropriate.
Plan for power, ventilation and fire safety
Follow the manufacturer’s placement and power instructions, keep air intakes clear and use the prescribed backup plan during outages or equipment failure. Keep smoking, flames and ignition sources away from oxygen equipment. Contact your provider for alarms rather than changing the flow yourself.

Frequently asked questions
Does an oxygen concentrator make 100% pure oxygen?
It delivers oxygen-enriched gas within the model’s specified concentration and flow limits; specifications vary.
Is a pulse setting the same as liters per minute?
No. Pulse settings and continuous-flow rates are different and are not directly interchangeable.
Can oxygen replace CPAP for sleep apnea?
Do not replace prescribed PAP with oxygen yourself. Your clinician determines the treatment needed.
Can I choose a concentrator only by size?
No. Its delivery mode and output must support the prescribed use.
What should I bring when comparing oxygen equipment?
Bring your prescription and details of use during rest, activity and sleep, plus information about your current equipment.
