Inogen One G3 Portable Concentrator Manual

Introduction

The air we breathe is made up of 21% oxygen, 78% nitrogen and 1% other gases.
Your Inogen One® G3 portable oxygen concentrator works by drawing in air and separating out oxygen from other gases using a filter system.
This filter traps some gases; but allows oxygen to pass through. This oxygen, now up to 95% pure, is delivered to you via your nasal cannula to assist in your breathing and ability to get out and about.
It is lightweight, compact, reliable and highly efficient. The Inogen One® G3 therefore gives you increased mobility whilst using oxygen.
BOC Homecare hopes that this product and the support, training and education we offer will benefit you and that, in turn, you will be able to get out and about as much as possible so you can live life to the fullest.

How to use the Inogen One® G3


Please read the important safeguards in the "Dos and don'ts" section and observe all warnings and cautions in this guide. Follow all operating instructions. If you have any questions or concerns please call BOC immediately on 0800 136 603.

  1. Device location
    Place your Inogen One® G3 device in a wellventilated location so the intake and exhaust vents are clear and unobstructed (the position of these can vary as pictured alongside). The device should also be located so auditory alarms can be heard.
    Device location
  2. Filters
    Ensure both intake particle filters (those with the blue plastic surround) are clean and correctly installed.
    Filters
  3. Battery
    Install the Inogen One® G3 battery by sliding it into place at the bottom of the device until an audible click is heard and the latch securing the battery to the device returns to the upper position.
    Battery
  4. Power sources (AC, DC, Battery)
    The Inogen One® G3 portable concentrator can operate from AC, DC or battery power, with the detachable battery acting as a secondary power supply in the event of power loss (AC or DC). Therefore, when operating the device from AC or DC power, you should always keep a properly-inserted battery in the unit. This will ensure uninterrupted operation and continuous oxygen production.
    AC operation (mains)
    Connect the AC power plug to mains power. Then connect the AC power output plug into the Inogen One® G3 device as shown below. The LED on the power supply will illuminate and a beep will sound from the concentrator.
    Power sources (AC, DC, Battery)
    DC operation (eg. car 12 volt)
    Connect the DC power plug to a 12 volt car power outlet or auxiliary DC power supply. Then connect the DC power plug into the Inogen One® G3 device as shown below.
    DC operation (eg. car 12 volt)
    Battery operation
    To operate the device via its detachable battery, install the battery by sliding it into place at the bottom of the device until an audible click is heard and the battery latch returns to the upper position.
    Battery operation
  5. Connect nasal cannula
    The oxygen outlet fitting is located at the top of the device. Push your high-flow nasal cannula tubing onto this, ensuring a good seal and tight fit between the tubing and oxygen outlet.
    Connect nasal cannula
  6. Turn on device
    Turn the device on by pressing the ON/OFF button. A single, short beep will sound after the logo is displayed. The display will show the selected flow setting and power condition. Following this, the device takes up to 2 minutes to warm up (longer if stored in a cold environment). During this time, the oxygen purity of the device is building to – but may not reach – specification. You should therefore leave the device to run for at least two minutes prior to use.
  7. Pulsed flow setting
    When powered up, the Inogen One® G3 device retains the previous setting it was used at. If you need to change this, use the "+" or "–" setting buttons to adjust to the desired setting (1, 2, 3, 4 or 5 pulsed flow). The current setting is viewed on the display. Note: you should only use the device at the setting prescribed by your clinician (or only change as clinically instructed).
  8. Oxygen delivery
    Position the nasal cannula on your face with the soft prongs sitting just inside your nostrils and breathe through your nose. The Inogen One® G3 device will sense the onset of inhalation and deliver a pulse of oxygen when you inhale through your nose. Thereafter, the device senses each breath and delivers oxygen every time you inhale through your nose, even if your breathing rate changes.
    Note: A green light will flash on the top of the unit each time a breath is detected. Make sure the nasal cannula is properly aligned on your face and you are breathing through your nose to trigger the device to deliver pulses of oxygen.
    Oxygen delivery
  9. Power OFF
    When you are finished using the device, press and hold the ON/OFF button for approximately one second. Store the Inogen One® G3 unit in a cool, dry location when not in use.

Battery charging

When out and about, your Inogen One® G3 device operates from battery power which will discharge over time. You therefore need to monitor the device's battery status and keep it charged up as required (the device display indicates the estimated remaining percentage (%) or minutes of available use).
When the concentrator detects that battery life is low (<10 mins remaining) a low priority alert will sound. When the battery is empty, the alert changes to a high priority. When battery life is low, do one of the following:
→ Plug the Inogen One® G3 into an AC or DC power source using the AC power supply or DC cable.
→ Replace the battery with a charged battery after turning off the Inogen One® G3 (by pressing the ON/OFF button). To remove a battery, press and hold the battery latch button and slide the battery away from the concentrator.
→ If the battery is drained, charge the battery or remove it from the concentrator.
→ If the Inogen One® G3 is being powered by the AC power supply or DC power, batteries will charge during operation.
→ Note: leaving your Inogen One® G3 device plugged in past full charge will not harm the concentrator or battery.
To ensure your battery is properly charging, use the correct AC or DC power cables and check that the display shows a battery-charging symbol (see p12 for examples). To take care of your device, only use Inogen One® G3 batteries as supplied by BOC Homecare.

Always:
→ Store device batteries in a cool, dry place.
→ Keep liquids away from batteries. If batteries become wet, discontinue use immediately and dispose of the battery properly.
→ If using multiple batteries, make sure that each battery is rotated-for-use on a regular basis. Batteries should not be left dormant for more than 90 days at a time.
