Frequently Bought Together

How to Operate Inogen G5 Portable Oxygen Concentrator?

  1. Place the Inogen One G5 in a well-ventilated location.
  2. Air intake and exhaust must have clear access. Locate the Inogen One G5 in such a way that any auditory alerts may be heard. Always operate the Inogen One G5 in an upright position
  3. Ensure particle filters are in place at both ends of the device.
  4. Insert the Inogen One G5 battery by sliding the battery into place until the latch returns to the upper position.
  5. Connect the AC input plug to the power supply. Connect the AC power plug to the power source and connect the power output plug to the Inogen One G5. The green LED on the power supply will be illuminated, and a beep will sound from the concentrator.
  6. Connect the nasal cannula tubing to the nozzle fitting. The nozzle fitting is located on the top of the Inogen One G5. The use of a single-lumen cannula up to 25 feet in length is recommended to ensure proper breath detection and oxygen delivery. Additional titration may be needed to ensure proper oxygen delivery when using a particular cannula. Consult your physician.
  7. Turn on your Inogen One G5 by pressing the ON/OFF Button. A single short beep will sound after the Inogen logo is displayed. Please wait. The loading icon will appear while the concentrator starts up. The display will indicate the selected flow setting and power condition. Following a brief start-up sequence, a warm-up period of up to 2 minutes will initiate. During this time period, the oxygen concentration is building but may not have reached specification. Additional warm-up time may be needed if your Inogen One G5 has been stored in extremely cold temperatures.
  8. Set the Inogen Concentrator to the flow rate your physician or clinician prescribes. Use the (+) or (-) setting buttons to adjust the Inogen One G5 to the desired setting. The current setting can be viewed on display.
  9. Position the nasal cannula on your face and breathe through your nose. The Inogen One G5 will sense the onset of inhalation and deliver a burst of oxygen at a precise time when you inhale. The Inogen One G5 will sense each breath and continue to deliver oxygen in this manner. As your breathing rate changes, the Inogen One G5 will sense these changes and deliver oxygen only as you need it. At times, if you inhale very quickly between breaths, the Inogen One G5 may ignore one of the breaths, giving the appearance of a missed breath. This may be normal as the Inogen One G5 senses and monitors the changes in your breathing pattern. The Inogen One G5 will normally sense the next breath and deliver oxygen accordingly.
