Ace the Test
Epinephrine receptors - ANSWER ✔✔alpha 1, alpha 2, beta 1, beta 2
Epinephrine dose - ANSWER ✔✔IV 2-10mcg/min
Epinephrine effects - ANSWER ✔✔increased systolic BP
- alpha receptors = vasoconstriction
- beta1 receptor = cardiac stimulant
decreased diastolic BP
- beta2 = dilation of skeletal muscle blood vessel
, Phenylephrine receptors - ANSWER ✔✔alpha 1
Phenylephrine dose - ANSWER ✔✔40-200 mcg/min
Phenylephrine effects - ANSWER ✔✔vasoconstriction, and reflex
bradycardia
Milrinone mechanism of action - ANSWER ✔✔Inhibits PDE-3 →
↑cAMP
↑ cAMP in heart: ↑[Ca]cytosol → inotropic
↑ cAMP in blood vessels: ↑Ca reuptake by sarcoplasmic reticulum →
vasodilation
Epinephrine mechanism of action - ANSWER ✔✔Direct-acting alpha
and beta agonist. Alpha: vasoconstriction. Beta-1: positive inotropic,
chronotropic, and dromotropic effects. Beta-2: bronchial smooth muscle
relaxation and dilation of skeletal vasculature. Blocks histamine
receptors.
milrinone - ANSWER ✔✔phosphodiesterase inhibitor
Septal leads and artery - ANSWER ✔✔V1, V2, - LM
Inferior leads and artery - ANSWER ✔✔II, III, aVF
