Inogen Intelligent Oxygen Delivery: How to Find Your Flow Setting

The Inogen One G5 and G4 portable oxygen concentrators deliver 90% (+6%/-3%) oxygen. The Inogen G4 has three flow settings: 1.0, 2.0, and 3.0, while the Inogen G5 has six flow settings: 1.0, 2.0, 3.0, 4.0, 5.0, and 6.0. The flow setting that is right for you will depend on your individual needs.

To select the right flow setting, you will need to consider the following factors:

  • Your doctor's prescription: Your doctor will have prescribed a certain level of oxygen therapy for you. This prescription will be based on your medical condition and your individual needs.
  • Your breathing rate: Your breathing rate is the number of breaths you take per minute. The faster your breathing rate, the more oxygen you will need.
  • Your inspiratory tidal volume: Your inspiratory tidal volume is the amount of air you breathe in with each breath. The larger your inspiratory tidal volume, the more oxygen you will need.

Once you have considered these factors, you can start to experiment with different flow settings to find the one that works best for you. You should start with the lowest flow setting and increase it until you feel comfortable. You should also talk to your doctor about the flow setting that is right for you.

Here are some additional tips for finding the right flow setting:

  • Using a Pulse Oxygen Oximeter is a must.  This device quickly checks your blood oxyen by just cliping on to you finger.  If you do not have one just ask us here at Main Clinic Supply, we are happy to provide one to you free of charge.
  • Pay attention to how you feel. If you feel short of breath or lightheaded, you may need to increase the flow setting.
  • Be aware of your surroundings. If you are exercising or in a high-altitude environment, you may need to increase the flow setting.

With a little trial and error, you can find the flow setting that is right for you and help you get the most out of your Inogen oxygen concentrator.

Continuous vs Intellgent Flow 

Continuous flow, just like the name suggests, metes out a continuous and steady stream of concentrated oxygen. 

Intelligent flow, on the other hand, delivers concentrated oxygen based on the user’s breathing rate. By sensing each inhalation, it dispenses oxygen as and when needed. This makes it ideal for all users, whether on the go or at home, awake or asleep.

Is a prescription required for oxygen concentrators like this one? Yes. According to the US Food And Drug Administration (FDA), all supplemental oxygen device purchases require a prescription.
