this might help. I have a page printed on dayglo yellow paper sitting in my ResMed travel case that lists the extra things I need to pack in addition to the blower & humidifier: mask & both cushions & headgear, hose, power cord, surge protector, power outage alarm, hose snuggy, non-slip pad for machine, bottle of water, vinegar & 7th Generation soap for cleaning. I'm so freaked about forgetting my mask or breaking its plastic shell that I take my former pillow mask too. I get all but the surge protector & liquids in my travel case, rest goes in makeup case. I haven't tried to fly with this stuff so it's just for conventions & in case of emergency situations (went to ER & they wouldn't release me, so a relative had to pack my stuff and this list helped as I was angry & upset that I hadda stay in the hospital and not thinking straight).
