How Does Inogen Produce and Deliver Oxygen?

by Mark Luther

Inogen portable oxygen concentrators (POCs) are proven to provide medical grade oxygen all day, every day. The proprietary Intelligent Delivery Technology is adaptable to changing environments while also monitoring oxygen delivery in order to minimize missed breaths.

How Intelligent Oxygen Delivery Technology Works

The Intelligent Delivery Technology found in all Inogen products utilizes triggering sensitivity to quickly detect a breath and deliver oxygen. As breathing rate slows, Intelligent Delivery Technology increases bolus doses. Intelligent Delivery Technology also has the ability to detect shallow mouth breaths at night, triggering a bolus dose based on a fixed minute volume. The efficacy of Intelligent Delivery Technology has been validated in clinical studies published in peer-reviewed journals.

Pulse Dose vs. Continuous Flow

Inogen POCs deliver oxygen via Pulse Dose mechanisms (as opposed to Continuous Flow). The Pulse Dose technology utilizes an oxygen conserver to deliver oxygen based on inhalation rates, allowing the proper amount of oxygen to be delivered during all phases of daily activity and during rest.

Benefits of Intelligent Delivery Technology

  • Provides medical grade oxygen all day, every day
  • Adaptable to changing environments
  • Monitors oxygen delivery to minimize missed breaths
  • Proven efficacy in clinical studies
  • Delivers oxygen based on inhalation rates
  • Provides the proper amount of oxygen during all phases of daily activity and during rest

What this article covers:

How Many Liters of Oxygen Does Inogen Produce?

Pulse dose oxygen delivery (PDOD) is a newer type of oxygen delivery that is more efficient than traditional low flow oxygen delivery. PDOD devices deliver oxygen only during inspiration, which reduces the amount of oxygen that is wasted during expiration. This can lead to improved oxygenation and reduced costs for patients who need oxygen therapy.

Traditional low flow oxygen devices deliver a fixed flow of oxygen over time. This means that the patient receives the same amount of oxygen, regardless of whether they are inhaling or exhaling. However, only a portion of the oxygen that is delivered during inspiration is actually absorbed into the lungs. The rest of the oxygen is exhaled. This can lead to wasted oxygen and increased costs for patients who need oxygen therapy.

PDOD devices deliver oxygen in a pulsed fashion. The device detects when the patient inhales and then delivers a pulse of oxygen. This pulse of oxygen is timed to coincide with the patient's inspiratory flow. This ensures that the patient receives the maximum amount of oxygen during inspiration.

PDOD devices have been shown to be more efficient than traditional low flow oxygen devices. A study published in the journal Thorax found that PDOD devices were able to improve oxygenation in patients with chronic obstructive pulmonary disease (COPD). The study also found that PDOD devices were able to reduce the amount of oxygen that was wasted, which led to reduced costs for patients.

PDOD devices are a newer type of oxygen delivery, but they have the potential to improve oxygenation and reduce costs for patients who need oxygen therapy. If you are a patient who needs oxygen therapy, talk to your doctor about whether PDOD is a good option for you.

Here are some additional benefits of PDOD devices:

  • They are more portable than traditional oxygen tanks.
  • They are quieter than traditional oxygen tanks.
  • They are less likely to cause skin irritation than traditional oxygen masks.

Here Is an Analogy to Help Understand Pdod and Inogen’s Intelligent Oxygen Delivery

A lay explanation of PDOD and Intelligent Oxygen Delivery is to imagine a water fountain. If a person stands in front of a water fountain flowing at 1 liter per minute, they will not actually drink 1 liter of water. The amount of water that the person drinks is a product of the number of sips and the size of the sip. The same principle applies to low-flow oxygen delivery. The net amount of oxygen that the patient inhales is a combination of the flow rate, the number of breaths, and the size of the breaths.

PDOD uses a different approach to oxygen delivery. Instead of delivering a fixed flow of oxygen over time, PDOD delivers a pulse of oxygen with each breath. The pulse of oxygen is timed to coincide with the patient's inspiratory time. This ensures that the patient inhales the maximum amount of oxygen with each breath.

PDOD has several advantages over low-flow oxygen delivery. PDOD is more efficient, meaning that the patient receives more oxygen for the same amount of oxygen flow. PDOD is also more comfortable for the patient, as it does not dry out the nasal passages.

PDOD is a new technology, and it is still being evaluated. However, it has the potential to revolutionize oxygen therapy.

Here are some additional details about PDOD:

  • PDOD is available in a variety of devices, including nasal cannulas, masks, and face tents.
  • PDOD is typically prescribed for patients with chronic obstructive pulmonary disease (COPD), asthma, and other conditions that can cause shortness of breath.
  • PDOD is safe and effective, and it has been shown to improve the quality of life for patients with chronic respiratory conditions.

Inogen GS-100 At-Home Oxygen Concentrator

This is a stationary model, meant to be used in the home. With the Inogen GS-100 At-Home Oxygen Concentrator, you’re supplied with a constant oxygen flow from 1 to 5 LPM.  This is the only inogen model that delivers constant flow oxygen.

Inogen oxygen production capacity in liters

That means it can only provide up to a maximum of 5 liters of concentrated oxygen per minute, but can also provide less depending on the setting you choose.

So, is a 5L oxygen concentrator any good? Based on our first-hand experience, 5 LPM is sufficient for the majority of oxygen users. As for the machine itself, check any Inogen GS-100 review and you’ll soon discover that it’s a top-selling home-use, reliable o2 concentrator, loved by oxygen users all over.

It’s quiet, energy-efficient, and offers a constant oxygen flow at your choice of 1-5 LPM. Although designed for home use, it is sleek and easy to move, with the option of a travel case for transportation. That means you can move it from one room to another, or take it with you if you relocate.
