Q

cardiogenic shcok description

A

the heart’s ability to contract and pump blood is impaired, and the supply of O2 is inadequate for heart and tissues

Q

septic shock pathophysiology

A

inflammatory response is overwhelming. vessels vasodilated and increased capillary permeability. leak into interstitial tissues. cytokines cause clotting

16
Q

septic shock s/s

A

tachycardia
HTN
increased lactic acid levels
hypoxic
hypo or hyperthermia

17
Q

septic shock hemodynamics

A

BP decreased
HR increased
CO decreased
SVR decreased

18
Q

septic shock treatment

A

measure lactate level
obtain blood cx X2 before abx
administer broad spectrum abx
administer 30 ml/kg crystalloid (NS and LR are crystalloids/isotonic fluids)
after 6 hrs apply vasopressors if needed. reassess.
early nutritional support

19
Q

neurogenic shock description

A

a loss of balance between parasympathetic and sympathetic stimulation causes vasodilation, leading to relative hypovolemic state

20
Q

neurogenic shock causes

A

spinal cord injury
anesthesia or other damage
meds, hyperglycemia

21
Q

neurogenic shock pathophysiology

A

overriding parasympathetic nervous system stimulation causes drastic decrease in SVR and bradycardia

22
Q

neurogenic shock s/s

A

bradycardia
dry warm skin
hypotension

23
Q

neurogenic shock hemodynamics

A

BP decreased
HR decreased
CO decreased
SVR decreased

24
Q

neurogenic shock treatment

A

restore sympathetic tone
cant do much to treat cause
support cardiovascular and neurologic function
prevent complications- dvts and internal bleeding (trauma)

25
Q

anaphylactic shock description

A

caused by a severe allergic reaction when patients who have already produced antibodies to a foreign substance develop a systemic antigen-antibody reaction

26
Q

anaphylactic shock causes

A

food, insects, meds that cause an allergy

27
Q

anaphylactic shock pathophysiology and s/s

A

5-30 min after exposure
2 or more of:
respiratory compromise
reduced BP
GI distress
skin and mucosal irritation

28
Q

anaphylactic shock hemodynamics

A

BP decreased
HR increased
CO decreased
SVR decreased

29
Q

anaphylactic shock treatment

A

remove agent if present first
IV fluids
epinephrine IM or IV
histamine blockers or bronchodilators

30
Q

compensatory stage of shock

A

normal BP
increased HR >100
increased RR >22
cold/clammy skin
decreased UOP
confusion or agitation
respiratory alkalosis

31
Q

progressive stage of shock

A

low BP
increased HR >150
increased RR, rapid and shallow
mottled skin
decreased UOP <0.5 mL/kg/hr
lethargy
metabolic acidosis

32
Q

irreversible stage of shock

A

low BP requires support
erratic HR
requires intubation
jaundice
anuric, requires dialysis
unconscious
profound metabolic and lactic acidosis
