Q

clinical features of shock (4)

A

tachycardia
tachypnea
possibly hypotension
signs of poor end-organ perfusion: AMS, oliguria, lactic acidosis, cool extremities, weak/thready pulse

1
Q

normal AVO2 difference

A

< 25-30

2
Q

causes of non-hemorrhagic hypovolemic shock (5)

A
GI losses
dehydration
burns
3rd space losses (inflammation)
neuro/renal (DI, DM)
3
Q

causes of hemorrhagic hypovolemic shock (3)

A

bleeding (internal/external)
operative
iatrogenic (open A-line, C-line)

4
Q

compensated shock sends blood to (4)

A

brain
heart
kidneys
liver

5
Q

compensated shock directs blood away from (3)

A

skin
GI tract
skeletal muscle

6
Q

management of hypovolemic shock due to bleeding

A

apply pressure to wound, elevate above heart

7
Q

obstruction shock is?

3 causes?

A

mechanical block to heart’s outflow

PE
cardiac tamponade
tension pneumo

8
Q

cardiogenic shock?

causes?

A

failure of the heart to pump effectively

damage to the heart muscle, MI, arrhythmias, cardiomyopathy, CHF, valve problems

9
Q

management of cardiogenic shock? (3)

A

inotrope
vasodilator if BP ok
constrictor if hypotensive

10
Q

management of septic shock

A

volume, then vasoconstrictor

11
Q

management of hypovolemic shock

A

volume, temporary vasoconstrictor until vol. restored

12
Q

types of distributive shock? (3)

A

septic shock
anaphylactic shock
neurogenic shock

13
Q

neurogenic shock results (3)

A

decreased PVR
increased vasodilation
hypotension

14
Q

what is distributive shock?

A

insufficient intravascular blood volume
relative hypovolemia
result of dilation of all blood vessels

15
Q

exaggerated endogenous inflammatory response

A

septic shock

16
Q

diagnosis of SIRS?

A

Two or more:
temp >38 or 90 beats/min
RR > 20 or PaCO2 < 32 mmHg
WBC > 12,000 or < 4,000 or > 10% bands

17
Q

whats the difference between warm and cold shock (2)

A

hyperdynamic/hypodynamic

flushed moist skin vs pale dry skin

18
Q

best ionotrope only?

A

Milrinone

19
Q

epinephrine functions?

A

potent ionotrope and vasoconstrictor

20
Q

dopamine vs dobutamine

A

dopamine has dose-dependent vasodilation
