Understanding How to Choose the Right Oxygen Concentrator

Are you in the market for an oxygen concentrator, but feeling overwhelmed by the variety of choices? Our comprehensive guide simplifies the process of choosing the right oxygen concentrator tailored specifically to your needs.

How Do Oxygen Concentrators Work?

These devices function by drawing in air from the environment, filtering out nitrogen, and delivering up to 95% pure oxygen. This function is essential as some medical conditions require higher oxygen concentrations than the average 21% found in natural air.

Determining Your Oxygen Requirements

The first step when you are choosing the right oxygen concentrator is understanding your oxygen needs. Monitor your oxygen levels during daily activities, rest, and sleep. Your doctor or respiratory therapist can guide you based on these data points, helping you choose an oxygen concentrator that can satisfy your oxygen needs.

Understanding the Types of Oxygen Concentrators: Continuous Flow vs. Pulse Dose

There are primarily two types of oxygen concentrators: continuous flow and pulse dose. Continuous flow oxygen concentrators offer a wider range of oxygen delivery, which may be necessary if you require 2 to 5 liters per minute of oxygen.

Conversely, pulse dose oxygen concentrators deliver oxygen in pulses when you inhale, making them a lighter and more portable choice, suitable for patients needing up to 2 LPM of oxygen.

How Your Lifestyle Affects Your Oxygen Concentrator Choice

When choosing the right oxygen concentrator, your lifestyle is a key factor. If you’re active and often on the move, a compact pulse dose unit might be ideal. If your oxygen requirements are high, you might need a continuous flow concentrator.

Planning for Future Needs

Remember, your oxygen requirements may increase over time due to the progression of your lung condition. Therefore, it’s wise to select an oxygen concentrator that can adapt to these changes. This might mean choosing a slightly larger model or a continuous flow device.

Choosing the right oxygen concentrator is a careful balance of meeting your current and future oxygen needs, fitting into your lifestyle, and offering you the utmost comfort and convenience. Always have a backup plan, as technology can sometimes fail.


Choosing the right oxygen concentrator might be challenging due to individual needs. However, by understanding your current and future oxygen needs, considering your lifestyle, and consulting with your healthcare provider, you can make the right choice. The ultimate goal is to improve your quality of life by providing you more mobility and freedom, regardless of your medical condition.
