Inogen One G2 Oxygen Concentrator background info

Inogen One G2 is battery powered. It offers a choice of 2 different battery sizes and can deliver up to 10 hours of oxygen therapy without connection to mains power supply. You can select a single 12 cell battery that provides 2 – 5 hours of operation from full charge or a double 24 cell battery that provides 8 – 10 hours of operation from full charge.

The Li-ion batteries recharge, when installed in the Inogen One G2 unit and the device is connected to AC or DC power sources. Recharging time is circa up to 4 hours for the single battery and up to 8 hours for the double battery.

When used with AC power source, the G2 oxygen concentrator automatically adapts to input voltage of between 100 V - 240 V (50-60 Hz), making the Inogen One G2 usable throughout the world. The DC power cable is designed to connect directly to cigarette lighters in cars or to auxiliary DC power supplies.  

Easy to use and reliable, the Inogen One G2 Portable Oxygen Concentrator dispenses oxygen anytime and anywhere at the turn of a button. There are 6 oxygen flow control settings and you can control the flow easily with control buttons (+ and -) from 1 – 6 litres per minute. Operating in the normal mode, the G2 concentrator delivers fixed volume of oxygen defined by the oxygen flow setting chosen.   

Default Mode and Breath Detection Alert Mode

  1. When the Inogen One G2 is powered up, the device operates in Default Mode with breath detection audible alert disabled. A crossed bell icon shows on the display.
  2. Equipped with automatic Breath Detection Alert Mode, the Inogen One G2 gives audible and visual alerts, if no breath is detected for 60 seconds, whilst it continues to deliver oxygen at a fixed rate of 17 bursts of oxygen per minute (i.e. 17 bolus per minute) until breathing is detected. A bell icon and flashing red light show on the display.  

Upon detection of breathing, the device switches back to the normal default mode and dispenses oxygen upon inspiration via the nose at a fixed volume determined by the oxygen flow setting (i.e. settings 1 – 6) as selected by the user.

When the nasal cannula is positioned on the face and you breathe through the nose, the G2 senses the onset of your inhalation and dispenses a burst of oxygen coinciding with the time of nasal inspiration. The Inogen One G2 senses each breath and delivers oxygen in synergy with breathing. As the Inogen One G2 monitors your breathing pattern throughout its entire operation, it can match oxygen delivery to your needs, despite of breath irregularities.   

Display screen features a push on backlight for easy reading. Backlight turns itself off automatically after 10 seconds to save battery power. Display screen shows information on flow settings, power status, battery life and errors. A red indicator light indicates a change in operating status or alerts you to an arising condition that requires action.

Please note that the purpose of the Inogen One G2 is not to sustain or support life. The G2 is intended to provide oxygen therapy with supplemental oxygen delivered via nasal cannula.

Caring for your Inogen One G2 Portable Oxygen Concentrator

Inogen One G2 is easy to maintain. All relevant instructions are enclosed in the user manual supplied with the device. If you are in any doubt, please contact us for help.

  1. You should regularly clean the outer case with moist cloth and replace your nasal cannula regularly as recommended by a manufacturer. Please note that a single lumen high flow cannula up to 25 feet long is recommended to ensure proper breath detection. Weekly cleaning of particle filter is required to ensure ease of air flow. Clean the particle filter with mild detergent and water, rinse and dry before re-use.  
  2. The output filter intended for protection of the users from inhalation of small particles should be replaced before the G2 concentrator is used by another person. As the output filter is located in a convenient position behind removable cannula nozzle fitting, the replacement of it can be performed by the user or by the supplier.        
  3. If you are using the DC input cable and the concentrator does not power up, you may need to replace the fuse located in the plug.
