Low dose epi predom acts on Beta receptors. so acting like isoproterenol
medium dose like dobutamine so predominantly on beta 1, bc its b2 effect will cancel with its increased alpha effects
and high dose epi = norepi.
so to answer your quesiton Map will go down, diastolic down(which is why your MAP goes down as map is 2/3rds diastolic) systolic will go up bc your contractility etc is going up, and pulse pressure will widen.
