Intelligent Delivery Technology®

Intelligent Delivery Technology® facilitates the delivery of a measured dose of oxygen when needed. In fact, Inogen’s oxygen delivery systems are designed to provide the necessary oxygen for most ambulatory patients during all phases of daily activity and during sleep.[1]

Proprietary conserver technology contained within Inogen portable oxygen systems ensures oxygen is delivered within the first 250 milliseconds of inspiration – where oxygen has the most effect on lung gas exchange. Inogen oxygen systems utilize triggering sensitivity to quickly detect a breath and deliver oxygen within this critical period. During periods of sleep, respiratory rates typically decrease. [1] Inogen portable oxygen concentrators (POC) actively respond to this changing physiology through its use of proprietary technology to increase the amount of oxygen delivered.  At 10 breaths per minute (BPM), the Inogen portable oxygen systems deliver double the amount of oxygen delivered as when the breathing rate is 20 BPM.

Intelligent Delivery Technology at Night

  • Due to its design, triggering-signal sensitivity, and pulse volume, Inogen portable oxygen concentrators have been proven to oxygenate patients during sleep, as well as rest and exertion. [1]
  • Intelligent Delivery Technology is highly flexible to changing environments and meters oxygen delivery through the system to promote increased oxygen delivery during sleep for most patients.
  • As breathing rate slows, Inogen’s Intelligent Delivery Technology increases each bolus dose.
  • Intelligent Delivery Technology detects even shallow mouth breaths at night, and triggers a bolus dose based on a fixed minute volume.

So what does that mean? For most people, oxygen systems like an Inogen POC will be sufficient as a primary oxygen delivery system, for all modes of use.

Now you can reduce your dependence on liquid oxygen systems and tanks with a portable oxygen system, such as an Inogen device. Inogen POCs may be used in a home, institution, vehicles and various mobile environments, all day, every day. If you use an oxygen concentrator, it is recommended that you maintain a backup oxygen system.
