I think the difference depends on where the infection is located, and you're right about the term RI being an all-encompassing term. If it's in the upper respiratory tract (URT), the nasal passages and sinuses are primarily affected (mucus from the nose and mouth, for example). If untreated, the infection can travel to the lower respiratory tract (LRT), and affects the lungs, often developing into pneumonia. With an LRT infection, you'll see difficulty in breathing, constant yawning and listing to one side as the lung fills up with crap.
Baytril seems to be the most commonly prescribed drug for infections of this sort, but there are others that are as effective and gentler on the turtle (so if you're dealing with a good herp vet, keep an open mind if they suggest something else). Dosage of drugs depends largely on the weight of the turtle.
