Hi Breathless22,
I assume that at home you use a small portable concentrator (the Inogen) for all the time you're awake, but have a larger stationary concentrator for nighttime use. Is that correct?
So, if that's the case, there are few factors to consider. First, is your Inogen concentrator a pulse dose or continuous flow? That may matter if you also have any issues with sleep apnea. Obviously, in order to trigger the flow if it's a pulse dose, you must be taking steady breaths continuously. Second, are you on the same flow rate day and night? If you use a higher flow at night, you must be sure your portable concentrator is able to provide that flow.
I would make a few calls to be sure. Inogen has a customer support center that can answer questions about your particular model(s). Also, just contact your doctor and ask their opinion - they have all your specific information and can tell you definitely if there are any issues.
I hope you have a great trip!
