After aggressive airway control, the next treatment choice would be epinephrine. Why would epinephrine be such a good choice?

Epinephrine has Alpha 1 & 2 beta 1 & 2 effects. Alpha 1 stimulation causes vaso constriction which works to counter the distributive shock. Alpha 2 stimulation regulates the amount of vaso constriction required to achieve desired results. Beta 1 stimulation increases the heart rate to increase cardiac output. Beta 2 stimulation dilates the bronchioles to counter act the reactive airway syndrome.
