Hi there, am going away with a friend who takes oxygen to manage their condition - they get a large cylinder and, I think, 2 small ones, delivered as needed. We are going down south for a visit to other friends.
It's only for two or three days, but twould be nice if she could have access to large cylinder O2 while away at these friends. Does anyone know if this is poss, or shall we just take the smaller ones with us and hope they are enough (we are going by train)?
