MAP calculation - [( 2xDBP) + SBP] / 3 cushing's triad - widened pulse pressure, bradycardia, and irregular respirations (indicative of increased ICP) chronotropes - affect the heart rate at the SA node (cardizem) inotropes - affect contractility (dopamine) dromotropes - affect automaticity of the heart ACE inhibitors adverse effects - dry cough, angioedema, renal impairment ARB (sartans) - block angiotensin 2 receptors, resulting in vasodilation antidote for vasopressor extravas...
