Shock

Question 1

types of shock

Answer 1

hypovolemic
cardiogenic
disributive
hypoxic
obstructive

Question 2

shock definition

Answer 2

hypoperfusion and/or cellular anaerobic conditions
sudden drop in blood flow through body

Question 3

hypovolemic shock

Answer 3

severe blood or fluid loss, heart unable to pump blood

parvo, foreign body

Question 4

Answer 4

caused by problem in heart - unable to pump properly

DCM

Question 5

distributive shock

Answer 5

issues with dilation and constriction of vessels

heat stoke, sepsis

Question 6

hypoxic shock

Answer 6

impaired oxygen delivery to cells

anemia, CO poisoning, respiratory disease

Question 7

obstructive shock

Answer 7

condition prevents blood getting back to heart
rare, emergency

blood clot, collapsed lung, pericardial effusion

Question 8

shock mechanism

Answer 8

low oxygen –> anaerobic respiration –> pyruvate build up –> lactic acid build up –> hyperlacticemia

Question 9

shock signs

Answer 9

lethargy
pale or very red mm (distributive shock red)
poor pulses
high or low HR
depression
collapse
cold extremities
bloated abdomen (obstructive)

common to all:
increased lactate
metabolic acidosis
mm colour change
weak pulses
increased HR (dogs)
decreased HR (cats)
