ELI5: What can't you inhale when you have your "breath knocked out of you"?

Your diaphragm is thrown out of sync, and it's what gives you that methodical inhale exhale ability.  If you get your breath knocked out of you it takes a couple seconds for the diaphragm to readjust and you can't inhale while that's going on.
