Shock

Question 1

shock

Answer 1

hypoperfusion and/or cellular anaerobic conditions

sudden drop in blood flow through body

Question 2

types of shock

Answer 2

hypovolemia
cardiogenic
distributive
hypoxic
obstructive

Question 3

hypovolemic shock

Answer 3

severe blood or fluid loss, heart unable to pump blood

parvo, foreign body

Question 4

cardiogenic shock

Answer 4

problem in heart, unable to pump properly

DCM, anything damaging myocardium

Question 5

distributive shock

Answer 5

dilation and constriction of vessels not responding properly

hear stroke, sepsis

Question 6

hypoxic shock

Answer 6

impaired oxygen delivery to cells

anemia, CO poisoning, respiratory disease

Question 7

obstructive shock

Answer 7

blood prevented from returning to heart (rare)

emergency

blood clot, collapsed lung, pericardial effusion

Question 8

hyperlactemia pathogenesis

Answer 8

low oxygen –> can’t produce ATP –> anaeorbic respiration –> pyruvate –> lactic acid build up

Question 9

signs of shock

Answer 9

lethargy
pale mm (or very red if distributive)
poor pulses
high (dogs) or low HR (cats)
collapse
cold extremities
bloated abdomen (obstructive)
increased lactate
metabolic acidosis

Question 10

GDV

Answer 10

twisted stomach
compressed vena cava –> reduced blood flow back to heart –> shock
