Default Cardiac function curves: Help

I am having trouble understanding cardiac function curves...I am using FA 2014 and there are three graphs given in it.I thought of writing my interpretation of the graph here so that anyone one of you will correct my mistakes and post the correct interpretation so that it would be helpful for me and others viewing this thread...Plz help

1.Excercise and AV shunt:

Increase in Cardiac output and Venous return and Mean systemic pressure stays the same.

2.Vasopressors:

Decrease in Cardiac output and venous return and Mean systemic pressure stays the same.

3.Fluid infusion and Sympathetic activity:

Increase in Venous return and Mean systemic pressure but cardiac output stays the same

4.Acute Hemorrhage and Spinal anesthesia:

Decrease in Venous return and Mean systemic pressure but cardiac ouput stays the same.

5.Catecholamines and Digoxin

Increase in Cardiac output but venous return and Mean systemic pressure stay the same.

6.Uncompensated failure and Narcotic overdose:

Decrease in Cardiac output but venous return and Mean systemic pressure stay the same.


Guys I know I m wrong but somebody can help me out especially the people who are using FA 2014..Is there any other source from which i can learn these curve properly..thank you

crossroad is 100% correct on that statement. Knowing the information from Dr.Kudrath's CVS lectures is amazing. His strategies will help you to easily understand those graphs in a short period of time.
