Question 2

cardiogenic shock Medical treatment

Answer 2

dobutamine
milrinone
nitroprusside

Question 3

dobutamine receptors and effect

Answer 3

beta 1, 2 → inotrope, ↑ CO/CI and therefore ↓ PAOP/PCWP

milrinone receptor and effect

Answer 4

CAMP inhibitor → inotrope

Answer 5

decrease afterload dt vasodilation

iGe, type 1

Question 16

hypovolemic shock CVP, PAOP, CO/CI, SVR, SVO2

Answer 16

CVP low
PAOP low
CO/CI low
SVR high then low
SVO2 low

Question 17

cardiogenic shock CVP, PAOP, CO/CI, SVR, SVO2

Answer 17

CVP high
PAOP high
CO/CI low
SVR high
SVO2 low

Question 18

obstructive shock CVP, PAOP, CO/CI, SVR, SVO2

Answer 18

CVP high 
PAOP depends on cause
CO/CI low
SVR high
SVO2 low

Question 19

distributive shock CVP, PAOP, CO/CI, SVR, SVO2

Answer 19

CVP low
PAOP low
CO/CI high then low
SVR low
SVO2 high because low tissue exchange
