breath in cold air

hi, I have a project for class involving cold weather, and i wanted my character to have his breath showing for the close up scene. the rest would be moving too fast to see it so it can be a cheap quick effect. i am trying to do this with a 2d fluid and have it set up to look the way i want it, except i don't know how to make it pause for his breathing. currently its always emitting and i need it to pause for a moment. how would i go about doing this? is there a emitter speed attribute? i couldn't find one, though i may be blind. thanks for help in advanced.

There used to be a tutorial on this exact effect by a guy who had a site called "painfulurination.com".

Back in April of last year his site went down, HOWEVER I found it on the wayback machine for you.

There is a speed attribute (is that the one you found?) but it might make more sense to key the particles/sec emission rate, otherwise you'll have a bunch of particles building up right at the emitter while it's "off". Does that make any sense?
