Finished Dead Space 3 yesterday.
Mr Light, If you mean collapsing as in
then yes, there is a timer. I had a similar moment, and on the respawn turned around and saw a giant churning maelstrom coming for me.
It was at that point I decided to run. Get to that fight as quickly as possible. Hit any enemies between there with stasis and just power past them. The occasional backwards walking to take out legs helped too. You're finally free of the maelstrom when you see a bench.
