A force choke on the other hand...
LnC Clark can hold his breath for 20 minutes, so he has some time to knock out the jedi before that becomes a problem. Silver Age Superman, on the other hand, could fly interstellar distances without breathing, so I don't think choking him, even with the Force, would do much.
I'm not sure what would happen if someone used the Force to pinch an artery, though. Presumably he still needs blood to his brain.
