Understanding Your Oxygen Order Before You Buy a POC
  • Oxygen is prescribed by a control of the flow rate, i.e., liter flow. The common 1-3 liters per minute continuous flow is not appropriate in all situations. This could be too much or not enough.

  • Precision in the use of the proper flow, or amount of oxygen, is necessary. The flow of oxygen should achieve the normal amount of oxygen in your blood, expressed as a saturation above 90%.

What to Know Before You Buy a POC
  • Portable Oxygen Concentrators produce oxygen, they do not store oxygen.
  • Portable concentrators produce varying levels of oxygen per minute, which allows for an acceptable dose of oxygen every breath you take.
  • Portable concentrators that weigh 2 to 8 pounds only deliver oxygen on-demand pulse flow. Manufacturers of these devices place arbitrary numbers such as 1-3 or 1-6 to refer to the size of the pulse flow of oxygen and are not the same as liter flow. These settings are considered liter flow equivalents. Also, these devices do not all produce the same amount of oxygen at a given setting.
Why Self-Monitor Before You Buy a POC
  • Many people commonly check their blood pressure, blood sugar or air flow rate (peak flow) at home. We can measure temperature and weight whenever we have the need.
  • We can now measure our blood oxygen and pulse rate at home as well, using a simple pulse oximeter. A common word used when measuring oxygen is titration.
  • Titrating is the measurement of what your oxygen equipment setting is achieving in the arterial blood. It’s the blood that energizes the tissue. By taking your own measurements, you can adjust your oxygen setting for any situation and with any portable oxygen concentrator
Who to Ask Before You Buy a POC
  • We understand that finding a portable oxygen concentrator that accommodates both lifestyle and oxygen needs can be a difficult process for both you and your loved one. Our respiratory team will take the time necessary to choose the right portable concentrator for your respiratory needs.
  • Our trial period on all portable oxygen concentrators assures your oxygen needs are met. 

* This is a general statement. Your physician must prescribe your specific target saturation level.

30-Day Risk-Free Trial

We understand that a portable oxygen concentrator can be a big investment. At OxiMedical, we give you 30 days (up to 15 hours of use) to decide if the portable concentrator you purchased is right for you. We recommend you visit your doctor or pulmonary rehab to assure you purchased the right portable concentrator.

Exchange – If you are not satisfied with the portable you purchased, we will exchange it for the portable that meets your needs. All exchanges must occur within 30 days from purchase date (limited to one exchange).

Return – You may return your portable concentrator within 30 days of purchase for a refund of the product sale price, less a $99 processing fee, which includes return shipping costs.

*See our Return Policy for full details.

Inogen One G3 Product Overview

Currently one of the smallest, lightest portable concentrators that produces medical oxygen and offers an extremely long lasting battery is the Inogen One G3. The oxygen machine was created to provide users with the highest level of independence. Smaller in size, lighter in weight, and produces more oxygen per pound than its predecessor, the Inogen One G2. Not requiring the use of a rolling cart, it is a portable concentrator that you can hold in one hand. You will never have to worry about oxygen running out, because this unit never needs to be refilled.

The Inogen G3 is ultra light, weighing less than 5 pounds with the 8 cell battery and 5.7 with a 16-cell battery and includes a carry bag that can be worn over your shoulder for easy mobilization. The batteries were created and piloted to last a very long time. At a setting of 2, the 8-cell battery can last up to 4 hours and the 16-cell battery can last up to 7 to 8 hours. With a faster than normal recharge time, the rechargeable batteries can reload in a few short hours. The 8-cell battery will recharge in 4 hours on average and the 16 cell battery will recharge in 6 hours. This unit is one of the smallest sized oxygen concentrators ever produced, measuring  only 7.25 inches tall, 3 inches wide and 8.75 inches long. With oxygen concentration levels at around 90%, It is a pulse dose portable concentrator that operates on setting from 1 to 5. At only 39 decibels, the machine is hardly noticeable. The unit can hardly be heard! So discreet that you can use it in a library or church without noticing it. Flow settings and battery life are beautifully highlighted on the easy to read LCD screen.

Airline approved for user ability during flights. Also can be used on most cruise ships and buses, making the Inogen G3 an excellent breathing companion for travel far and near!

Included in the Inogen One G3 Starter Package is: 8 cell battery, AC power supply, DC power cable, carry bag, cannula, and manual.
