concept of cardiac after load Flashcards
1
Q
what is after load
A
amount of resistance the heart must pump against to eject blood
2
Q
after load is greater on the right or left ventricle and why
A
left
left ventricle wall is thicker and receive a greater preload Than the right
3
Q
most sensitive measure for the left ventricle after load
A
systemic vascular resistance (SVR)
4
Q
most sensitive measure for the right ventricle after load
A
pulmonary vascular resistance (PVR)
5
Q
what happen with the after load with heart disease
A
decrease blood flow to the heart= decrease venous return = decrease after load
6
Q
parameter of after load
A
pressure
7
Q
parameter of preload
A
volume
8
Q
after load depend on
A
arterial blood pressure and vessel tone
