I use a CPAP machine. So I am "light packing" challenged. I know I'll need to bring adapters. Will this cause a problem with mobility issues on the trips?
I’m confused. Why would bringing a CPAP along cause a problem with mobility issues?
Only you know whether you can comfortably carry a CPAP while moving between airports, hotels, trains, buses etc. And only you know how often you're moving around and what sort of transport you're using.
Having seen modern CPAPs, I wouldn't have thought it would be a problem.
But maybe I'm misunderstanding the question.
From your other question, and this one, I'm guessing you are asking is in regard to a Rick Steves tour? Am I correct?
If so, you can bring whatever you want as long as you can handle it between the coach and the hotel/your room.
In regards to prescritpions, RS will never ask you what you are taking in regard to medication. It's none of their business.

In case you are referring to Rick Steves tours, you are not restricted to one carry on size bag, it's a suggestion, but you must be able to handle your luggage yourself.
It might surprise you to know that many participants in the forum do not travel on the tours, so it's helpful to post in the RICK STEVES TOURS section, or mention it in your posts to get the most useful answers.
I know insurance coverage may be a big factor, but depending on the age of your unit, consider upgrading it to a travel one, or at least one of the newer lightweight model (of course, not knowing what you have).
Newer models should also be 120V/240V compatible, so all you should need is an adapter, either a Type C for most EU countries, and/or the UK adapter, if that applies.
A question that often comes up is about distilled water, it is available in most of Europe, but for short periods, simple purified bottled water works fine. The concern is long-time build up of calcium and iron, a several week trip is not a problem using purified water.
