Designed for an active life

Your pace of life will not prevent you from using the Inogen One G4 Oxygen Concentrator, which weighs only 1.27kg. (with the single battery of up to 2.40 hours) and is the smallest on the market (15 cm. high x 6.8 cm. wide x 18.2 cm. long).

Unlimited departures

You can go anywhere you want! This is possible because you can charge your battery both at home with the AC charger and in the car with the cable.

There are two types of batteries for the Inogen One G4 concentrator with a different life span: up to 5 or 2.40 hours.

  Single Battery  Double Battery
Setting 1 2 hours 40 min. 5 hours 
Setting 2 2 hours 15 min. 4 hours 30 min.
Setting 3 1 hour 20 min. 2 hours 30 min.

Inogen Quality

As with the entire range of Inogen concentrators, the oxygen supply is produced in pulse flow, also known as "on demand". This means that the device detects inspiration through the sensor and sends the oxygen bolus through the nose goggle.

The Inogen One G4 concentrator provides up to setting 3 (equivalent to 3 liters per minute).

In addition, it is ready to be used 24 hours a day, 365 days a year.

Advantages and disadvantages

If you already know the previous Inogen oxygen concentrators, here are the differences from the Inogen One G3 concentrator:

Inogen One G4  Lighter: 1.27 kg Smaller: 15x6,8x12 cm. 40 dBA Up to setting 3
Inogen One G3 2,2 kg. 18,4x7,6x22,2 cm. 42 dBA. Up to setting 5

Minimal maintenance

The Inogen One G4 concentrator requires minimal patient maintenance. It is only necessary to clean the external filters by removing any external agents such as dust.

However, here are some tips for improving the condition of the device:

  • It must be well ventilated, avoiding covering it with blankets or covering the ventilation slots of the equipment.
  • Heat sources such as radiators should be avoided or left in the vehicle.
  • Do not smoke, whether it is the patient or the people around him/her.
  • If the equipment will not be used for more than a week, it is advisable to remove the battery.
  • It should always be worn with a nose goggle. If an oxygen therapy mask is used, the effectiveness of the treatment will be lost. This is because the sensor would not detect the patient's inspiration as there is too much dead space.
  • It is not recommended to add an oxygen extension as it may be necessary to increase the flow setting.
