Product Description

Inogen One G4 Portable Oxygen Concentrator w/ Single Battery Model#IS-404

With the Inogen One you can jump in the car to run errands, take a weekend trip to see family, or even take it on a plane to go on vacation!

The Inogen One G3 is one solution for oxygen at home, away, and for travel, 24/7. It’s oxygen therapy on your terms.

The design allows the freedom and independence that are missing with traditional devices. This portable concentrator can be used for stationary or portable oxygen for traveling. The Inogen G4 Concentrator can be powered from three separate power sources: a rechargeable lithium ion battery, AC power, or DC power. The AC power supply is auto sensing, allowing worldwide use. The oxygen flow is pulse dose with five settings from 1 to 3. Oxygen concentration levels are from 87 to 96 percent with a maximum flow of 840 mL. Noise output is a modest 39 decibels. It is capable for use for both day and night while on extended vacations

Intelligent Delivery Technology at Night

  • Unlike traditional oxygen systems, such as portable tanks, or even other portable oxygen concentrators, the Inogen One G4 is proven to provide oxygen to users during rest, exertion, and sleep.
  • Intelligent Delivery Technology is highly flexible to your changing environments and automatically adjusts the oxygen delivery to promote increased oxygen delivery during sleep for most patients.
  • Typically your breath rate slows down as you sleep and perhaps, becomes more shallow. As this happens, Inogen’s Intelligent Delivery Technology increases each bolus size so you receive the same amount of oxygen per minute.
  • Intelligent Delivery Technology detects even shallow mouth breaths at night, and triggers a bolus dose based on a fixed minute volume.
