Innovative

The Inogen One G4 provides the oxygen user with 3 different flow settings. The Inogen One G4 also includes the "Intellegent Delivery" technology. This system detects a breath, after which a pulse of oxygen is delivered in the first 400 miliseconds. With this technology, the Inogen One G4 is an innovative system and sets it apart from the competition. This technology is of vital importance because most gas exchange in the lungs occurs during this 400 miliseconds. By delivering oxygen at the start of a breath, the Inogen One G4 ensures that the body uses the oxygen in a more efficient way.

Easy to change columns

The columns of the Inogen One G4, also known as sieve beds, are positioned in such a way that they can be changed by the user easily. The columns filter the nitrogen out of the air, leaving pure oxygen. After time, their effectiveness can decrease. Other oxygen concentrators have to be sent in for repair, but with the Inogen One G4 you can easily change them yourself.
