Vascular function curves

Question 1

What effect does increasing cardiac output have on right atrial pressure?

Answer 1

RAP will decrease

Question 2

What effect does changing blood volume have on right atrial pressure?

Answer 2

Increasing BV will increase RAP

Decreasing BV will decrease RAP

Question 3

What effect does changing venous compliance have on right atrial pressure?

Answer 3

Decreasing compliance increases return of blood, RAP will increase.
Increasing compliance decreases return of blood, RAP will decrease

Question 4

What effect does changing the arterial resistance have on right atrial pressure?

Answer 4

Increasing the peripheral resistance at a given level of CO will increase mean arterial pressure and
RAP in proportion to the level of CO.
Decreasing the peripheral resistance at a given level of cardiac output will decrease MAP and RAP in proportion to the level of cardiac output
