Pulse Dose vs. Continuous Flow: What's the Difference?
Pulse-dose oxygen is delivered when the concentrator detects inhalation. Because oxygen is delivered intermittently rather than continuously, pulse-dose concentrators can generally be made smaller and lighter.
Continuous-flow oxygen is delivered continuously at the prescribed liter-per-minute rate. Portable concentrators capable of continuous flow are generally larger because they must produce more oxygen.
A pulse setting is not equivalent to the same number of liters per minute of continuous flow. Your oxygen prescription and healthcare provider should determine the appropriate oxygen delivery method and setting.
How to Choose a Portable Oxygen Concentrator
1. Start With Your Prescription
First determine whether your prescription calls for pulse-dose oxygen, continuous flow, or a specific continuous liter-per-minute requirement. Flow requirements should be considered before size, weight or battery life.
2. Compare Weight & Battery Needs
A user who mainly needs oxygen for errands may prioritize a lightweight system. Frequent travelers or people away from electrical power for longer periods may place greater importance on battery capacity and additional batteries.
3. Consider Warranty & Support
Portable oxygen concentrators are medical devices. Warranty coverage, manufacturer support, replacement parts and access to knowledgeable assistance should be considered along with purchase price.
How long will a portable oxygen concentrator battery last?
Battery runtime varies substantially by model, battery size and oxygen setting. For a more detailed explanation, see our portable oxygen concentrator battery life guide .

What is the lightest portable oxygen concentrator?
Among the models compared on this page, the OxyGo FIT Plus is the lightest at approximately 2.9 lbs with its standard battery. It is a pulse-dose concentrator with settings 1–4. Weight alone should not determine which concentrator is appropriate for a user's prescription.
What is the difference between the OxyGo FIT Plus and OxyGo NEXT NG?
The OxyGo FIT Plus is the smaller and lighter of the two and provides pulse-dose settings 1–4. The OxyGo NEXT NG weighs approximately 4.8 lbs and provides pulse-dose settings 1–6, along with larger battery options. Both are portable pulse-dose oxygen concentrators with 5-year warranties.
Do I need pulse dose or continuous flow oxygen?
Pulse-dose concentrators deliver oxygen in response to inhalation, while continuous-flow concentrators deliver oxygen continuously at a prescribed liter-per-minute rate. Your prescription and healthcare provider should determine which oxygen delivery method and setting are appropriate for you.
Which portable oxygen concentrators provide continuous flow?
The Oxlife Liberty 2 provides continuous flow up to 2 LPM as well as pulse-dose operation. The larger Oxlife Independence provides continuous flow up to 3 LPM and also provides pulse-dose operation.
Are portable oxygen concentrators FAA-approved for flying?
Many medical-grade portable oxygen concentrators are FAA-approved for use aboard commercial aircraft, including the models compared on this page. Travelers should verify that their specific concentrator is approved and follow their airline's procedures and battery requirements before travel.
How long do portable oxygen concentrator batteries last?
Battery runtime depends on the concentrator, battery size, oxygen setting, breathing rate and operating conditions. Higher oxygen settings generally reduce battery runtime. Read our complete POC battery life guide for a more detailed explanation.
Which portable oxygen concentrators are made in the USA?
Inspired Portable Oxygen specializes in USA-made medical-grade portable oxygen concentrators, including OxyGo models. Manufacturing origin varies by manufacturer and model, so buyers should verify the specific concentrator when comparing systems.
What is the Drive DeVilbiss iGo2 portable oxygen concentrator?
The Drive DeVilbiss iGo2 is a portable pulse-dose oxygen concentrator with settings 1–5 and a weight of approximately 5 lbs. It is another portable option for users whose prescription is appropriate for pulse-dose oxygen delivery.
Important: Portable oxygen concentrators are prescription medical devices. Product specifications and battery performance can vary by configuration and operating conditions. Always follow your prescribed oxygen setting and healthcare provider's instructions.
