Cardiac Function Curves + Venous Curves

Question 1

What is Mean Systemic Filling Pressure (MSFP)

Answer 1

x intercept, CO=0. average pressure in the systemic circulation when there’s no blood flow.

Question 2

What is the relationship between MSFP and RAP?

Answer 2

A higher MSFP with a lower RAP leads to greater venous return.

Question 3

Diastolic Blood pressure is analogous with which what cardiac parameter

Answer 3

Afterload/TPR
Decrease in DBP means Decreased Afterload
