General Anesthesia Effects on Cardiac Output and Blood Pressure

Fluctuate randomly due to anesthetic medications

Decrease due to myocardial depression and vasodilation (correct)

Increase due to increased myocardial contractility

Stay the same due to neutral effects on the cardiovascular system

No effect on venous return

Decrease venous return by abolishing normal muscle tone (correct)

Increase venous return by enhancing muscle contraction

Decrease venous return by maintaining normal muscle tone

They help maintain normal blood pressure levels

They increase heart rate, improving cardiac output

They slow heart rate, further decreasing cardiac output and blood pressure (correct)

They have no effect on cardiovascular parameters
