Typically we put SCDs on any patients who have general anesthesia for more than 45min, unless we're doing leg surgery. Our old machines used to not work only hooked up to one SCD, and most people aren't in the habit of putting only one on. We have a committee doing research to see if we can go to a standard order of "if under anesthesia for x min, they go on."
When you are just lying around you are still using muscles in your legs, however subtle the movements are. When you are chemically paralysed (as is often the case during general anesthesia) the muscles are incapable of moving and therefore the blood in your legs is prone to pooling/clotting.
That's sort of what I figured, but I wanted to be sure. It begs the question, though: long flights. Is the DVT risk there due more to the pressurization of the cabin or sitting? Because even on a long flight, you can still move your legs around a fair amount, yet they still warn about DVT concerns.

Cabin pressure is supposed to be similar to ground level pressure, so it should not have an effect. Most people move their legs very little during flights because they are packed in like sardines.
"Experts think that sitting for hours together in cramped spaces and dehydration triggers these blood clots"

Do you put sequentials on all patients or just older patients?
