I've traveled extensively and always bring my vest, nebs and all meds. Skipping treatments on a vaca is, for me, a guarantee I'll be paying the price once I get home.
I could rely on hubby for chest pt, but I prefer to have my independence, and him his freedom.
I even brought my vest to Egypt. The vest is fine for travel anywhere bc it has built in converters so all you need is a plug adapter and you are set worldwide.
The nebulizer compressor is more tricky. I've tried every single option out there and bottom line you will need an adapter and transformer, and even then it will probably blow. They are bulky to carry around the world.(frying my pari neb in the back woods of Austria was not fun) lol
The better option is to buy a pari trek. The only thing that needs to be charged is the battery pack and you only need an adapter for that. Buy a spare battery pack to have enough power to get through a long pt session. One charged battery will only last 45 mins. The pari treks give a slower neb time.
Its not fun sterilizing nebs while traveling. I buy the pari disposable nebs for trips. They are super light and pack well. (like $50 for a box of 100)
For traveling with chilled meds, the FRIO insulin cooling cases are amazing. (get them from Magellan's online for $25) I use them for every flight. They keep meds chilled a full 24 hrs, no ice or fridge needed. You can reuse them again and again. I also love Magellan's night/day pill case. One of them kept all my meds/vits secure for a full 3 wk trip. Nice to not bring big bottles with you. But always tear off your prescrip labels and bring them along, just in case.
Planning well, doing your research ahead of time will ensure a good trip where you come home healthy. Above all, enjoy your traveling.
Even if its just Disney World...
