Q
Where in the circulatory system is the highest pressure and the lowest pressure?
A
Highest: Left ventricle
Lowest: Right atrium
3
Q
From the hemodynamic perspective, what is the blood flow (Q) equation?
A
Q= MAP / TPR
4
Q
MAP equation
A
Arterial pressure - Venous pressure
5
Q
Arterial pressure equation
A
2/3 DBP + 1/3 SBP
6
Q
What is central venous pressure and it’s range
A
Pressure taken from the vena cava or right atrium, ranges from 0-8mmHg

Q
TPR equation
A
TPR= viscosity x length / rˆ4
