If your CPAP has a detachable humidifier resevoir, consider detaching it and leaving it at home. NY is considerably more humid than CO so it's not essential to have it there as it is here and the space saving in luggage is worth not taking along. I just travelled overseas for a month without the humidifier along and was fine the entire time.

I packed my CPAP into my checked luggage so I can't advise from experience on taking it in carry on except to say TSA will likely have you get it scanned separately like any other electronics.
