I assume you're thinking about feeding issues?

Tip it upside down, look at the bottle, you should see some air bubbles. If you don't, then the reservoir is full.
Tip it back up and squeeze the bottle (sort of hard) and you should hear a gurgle, take a drag without pressing the button and see if the atty gurgles. If it does, you're good to go.
