Why can't I prolong the sound i mean my air?

Seanix, maybe you could explain your situation with more detail. What exactly is happening?

alright, what i mean is i really cant sustain my air a little bit longer. i may out of air, and may fall or may breathe in the wrong part. i mean in the phrase. probably i don't know how to control my air that it will sustain further more.. thanks
