How to Stay Focused while respawning.

How do you stay focused in a long game? Take one of my last matches for example. I was doing well up until I had died. I knew at that point I lost concentration during that 1 minute death and I played awfully right after I respawned. I hadn't died much all game but died immediately after respawning and possibly threw the game. I have no idea how to keep my rhythm or concentration while dead.
