Health & Medicine

Ok, heres the story. I was teaching this otherwise sharp EMT-Basic class that bombed two respiratory emergency tests in a ROW!
So this is the remedial lecture I inflicted on them. I don\'t know if they passed because of this fine work, or just because they were afraid of another lecture fo they failed.

Hope its useful to you.
