The display will indicate the selected flow setting and power condition. Following a brief start-up sequence, a warm up period up to 2 minutes will initiate. During this time period the oxygen concentration is building to but may not have reached specification. Additional warm up time may be needed if your Inogen One G4 has been stored in extremely cold temperatures.

  12. Position the nasal cannula on your face and breathe through your nose. Inogen One G4 will sense the onset of inhalation and deliver a burst of oxygen at a precise time when you inhale. The Inogen One G4 will sense each breath and continue to deliver oxygen in this manner. As your breathing rate changes, the Inogen One G4 will sense these changes and deliver oxygen only as you need it. A green light will flash each time a breath is detected. Make certain that the nasal cannula is properly aligned on your face and you are breathing through your nose.
