Defending a side choke while on the ground

You are on your back and the attacker is kneeing on your side and choking you. You have to react quickly otherwise you're going to pass out in few seconds.
Pluck one of the choking hand to release the pressure on your throat; with your other hand push the attacker at his windpipe in order to create some distance; then insert your knee against the attacker's abdomen and push him away: continue with multiple kicks to the face; stand up and escape.
