What do vasopressors do? increase BP Which drug: -increases MAP and SVR w/a mild decrease in CO infusion: 0.01-0.04 units/min -few side effects and allows for dose reduction of other pressor infusions vasopressin Which drug has an indication for septic shock b/c endogenous hormone is low? vasopressin Which drug: -endogenous central neurotransmitter and the response varies w/dose -used to increase contractility and HR dopamine Which drug has an indication for hypotension, low urine output, low HR,? dopamine When should you notify provider when patient is on dopamine? tachycardia, arrhythmia, HTN Which drug: potent beta-1 agonist and moderate beta-2 agonist, positive inotrope w/decreased PAWP and SVR and little change in HR dobutamine What is the infusion rate for dobtuamine? 2-20 mcg/kg/min What are the indications for dobutamine? chf, cardiogenic shock and shock w/increased PAWP Which drug: relaxes vascular and tracheal smooth muscle, increases contractility but there is a potential for reflex tachycardia milrinone What is the iv infusion for milrinone? 0.375-0.75 mcg/kg/min What is milrinone used for? cardiogenic shock, right sided hf Which drug: potent beta 1 and 2 agonist, significant decrease in SVR, MAP, PAWP w/a increase in HR isoproterenol What is the infusion rate for isoproterenol? 0.001-0.1 mcg/kg/min What do chronotropes do? increase heart rate What do vasodilators do? relax smooth muscle, dilate blood vessels and decrease b/p Which drug: decreases preload by making the "tank" bigger and keeping volume status nitroglycerin If you give a low dose of nitro, what happens? venous dilation If you give a high dose of nitro, what happens? arterial/venous dilation What are the indications for nitroglycerin? short term management of MI, CHF What is the iv infusion rate for nitroglycerin? 5-20 mcg/min Which drug: arterial vasodilation, very potent antihypertensive and unlike other vasodilators, it causes minimal increase in HR -very expensive nitroprusside What is the infusion rate of nitroprusside? 0.25-5 mcg/kg/min
