What To Consider Before Buying An Oxygen Concentrator

Inogen One G5 – Battery Overview

When purchasing a portable oxygen concentrator, our Reviews Team recommends you consider the following criteria:

  • Price: The cost of portable oxygen concentrators varies from approximately $2,500$4,000. Most people are guided by their budget when choosing the concentrator thats best for them.
  • Weight: Most models range from around 320 pounds. If youre concerned about weakness or fatigue, a lighter model might be best for you.
  • Battery life: Most portable oxygen concentrator models last between 25 hours on a fully charged, rechargeable battery. If you enjoy traveling, visiting family or friends, and being outside the home, youll want to choose a machine with a longer battery life.
  • Noise level: One concern many portable oxygen users have is the sound coming from the machine, as they dont want it to be distracting to others. If youre looking for a quieter unit, look for a machine with lower decibels.
  • Wearability: Users can wear portable oxygen concentrators in various ways, such as with an adjustable strap draped over the shoulder, a carrying bag that looks similar to a bag or purse, or a backpack. If independence is a priority, finding a concentrator that is the most comfortable for you is important. When researching portable oxygen concentrators, ask the company how customers usually wear their machines.

    Flow Settings Of The Inogen One G4 Vs G5

    One of the most measurable differences between the Inogen G4 and Inogen G5 systems is their oxygen output and flow settings. As you can see in the side-by-side comparison, each model has a different maximum output, but they also have different flow settings to accommodate individual needs. Flow settings are numbered and each number setting indicates an amount of oxygen delivered per breath.

    Its important to note that the numbered settings are considered more like power levels, and each number represents a different volume of oxygen delivered per pulse. To help clarify this difference, the chart below shows the settings and corresponding oxygen volume per breath for each model.

    Flow Setting
    Inogen One G5 oxygen volume per breath 74 ml

    Note: This chart is for basic clarification purposes only, and specific settings and oxygen volume needed should be discussed with and prescribed by your doctor.

    The Inogen One G4 system has a maximum oxygen output of 630 milliliters per minute, with flow settings from 1 to 3. With only three flow settings, this system isnt as able to accommodate exact oxygen needs as some others, but overall, its designed for users with lower oxygen prescriptions.

    On the other hand, the Inogen One G5 system has more settings, a higher maximum output of 1,260 milliliters per minute, and can accommodate more specific or more exact oxygen delivery needs.
