shallow breathing, but may also result in the occasional trigger due to motion of the
cannula or motion of the concentrator. The trigger sensitivity may vary.
2.4.3. Flow Setting Selection Relative to Physician Prescription
Inogen has labeled each of the six settings to provide a guideline for matching the setting

correlation is dependent upon the patient’s breathing rates, inspiratory tidal volume, and
other physiologic factors. Inogen suggests that each patient be titrated (a) while
sedentary, and (b) while active or ambulatory.
