How do you give diluted epinephrine (1:10000) through an injector needle?

  1. It typically takes 1.5ml of fluid (epi) to prime the endo injector needle, right? So, in injecting epi for a bleed, doesn't 1.5ml of NS follow the total injection of the epi syringe to deliver the full 1mg of epi? How do you keep track of how much epi you give? Just want to clarify.
