This because dopamine because it has postive inotropic effect , chronotropic effect on the heart ( activate B1 receptrors ). It overcome hyptension by activation of alpha receptor . it activates also the dopaminergic receptors in renal and splanchnic arterioles , thus increase blood flow to the kideny and other viscera . this protect the kideny in case of cardiogenic shock .Adrenaline did not provide this protection even may reduce blood supply to these vital organ.

What is the goal of combined dopamine and nitroprusside therapy?
Dopamine vasoconstricts, so it increases the blood pressure in cardiogenic shock. Nitroprusside is a vasodilator, it decreases preload (left ventricular stretch) and afterload (resistance). They are used in combination in cardiogenic shock to achieve a good hemodynamic effect or "good balance" or adequate blood flow.
What is the pathophysiology of shock?
Cardiogenic, hypovolemic, or septic shock?
Which part of the heart fails to work effectivly during cardiogenic shock?
Ventricles of your heart fail to work effectively in cardiogenic shock. Cardiogenic shock usually fallow the heart attack, also called as myocardial infarction.
What is the difference between dopamine and dobutamine?
Dobutamine is a drug that acts on the sympathetic nervous system. Physicians use it to treat heart failure and cardiogenic shock. Dopamine is a neurotransmitter that our bodies produce in order to send signals between brain cells.
What is cardiogenic shock?
Cardiogenic shock means when the heart has been damaged so much that it is unable to supply enough blood to the organs of the body. :) your welcome
What type of shock does cardiac tamponade predispose a patient to?
cardiogenic
What are the kinds of shock?
Distributive, cardiogenic, neurogenic, septic, hypovolemic
What type of shock is caused by inadequate function of the heart?
cardiogenic
What are the 4 major types of shock?
The four major types of shock are hypovolemic shock (caused by low blood volume), cardiogenic shock (caused by heart failure), distributive shock (caused by vasodilation), and obstructive shock (caused by an obstruction to blood flow).
What causes nausea during cardiogenic shock?
Cardiogenic shock occurs when the heart is not adequately circulating blood due to an abnormal rhythm. Nausea is based in the brain so I suppose the lack of oxygen would be the cause.
What causes nausea during a heart attack?
Cardiogenic shock causes the nausea.
Why does Cardiogenic shock cause nausea?
In the cardiogenic shock, blood circulations slows down to various parts of the body, including the brain. You have a center that controls vomiting in your brain, it is in your medulla oblongata, and this decrease in blood circulation caused by cardiogenic shock also affects the region where that vomiting center is, with this it will be activate and nausea will arise.Source: i researched physiology documents because hypotension causes nausea, and i believe the mechanism is the same.
