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 e...

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 hypotens...

CEN - CARDIAC REVIEW EXAM REVIEW QUESTIONS AND ANSWERS, RATED A+ Atropine has what affect on the heart - -reverses cholinergic-mediated decrease in heart rate (increases heart rate) Describe afterload - -The pressure the heart must eject against in the aorta measured by blood pressure, specifically MAP (mean arterial pressure) Describe Mobitz Type I - -PR interval gets longer and longer until and QRS complex is dropped. Describe Mobitz Type II - -PR interval remains normal at 0.12 and ...

Cardiac output = - CO + HR x stroke volume (amount of blood ejected per contraction) Primary compensatory mechanism of low Cardiac output in peds? Other signs? - Tachycardia -- Peds are unable to increase stroke volume. Hypotension is a late sign, and bradycardia is an ominous sign in peds. Stroke Volume is influenced by... - Contractility, preload, and afterload. Frank-Starling's Law -- Stretch heart with volume to increase contractility (rubber band snapping shut) Preload is eval...
