Yeah, there's not much you can do except to lay flat on the floor(to spread out the impact force) with your hands underneath your head, and pray.
Jumping will do little.
An alternative might be to hold onto something overhead(feet off the ground)
Upon inpact, your fingers will be ripped from what your holding, your shoulders will probably be severely dislocated, and you will probably break both legs.
But hey, you might survive!
