SHOCK

Question 1

what is shock?

Answer 1

clinical syndrome of tissue hypoperfusion due to circulatory failure

Question 2

what happens in cardiogenic shock>

Answer 2

there is decreased force of contarction of heart and sometimes decreased heart rate. this causes a decrease in cardiac output and so MAP decrease. there is compensatory increase in systemic vascular resistance causing

COOL CLAMMY PERIPHERIES

Question 3

name some causes of cardiogenic shock

Answer 3

ischaemia

valve disease

Question 4

what happens in obstructive shock

Answer 4

there is obstruction to cardiac outflow

get venous back pressure causine

RAISED JVP AND DISTENDED NECK VEINS

Question 5

name some causes of obstructive shock

Answer 5

PE

tension pneumothorax

Question 6

what happens in hypovolaemic shock

Answer 6

there is decreased blood volume

lover venous return to heart

reduced force of contraction and reduced cardiac output

Question 7

name some causes of hypovolaemic shock

Answer 7

dehydration

haemorrhage

Question 8

what happens in disruptive shock

Answer 8

decreased systemic vascular resistance due to vasodilation

Decreased MAP and compensatory increase in cardiac output

WARM RED PERIPHERIES

Question 9

describe the basic pathophysiology of shock

Answer 9

mean arterial pressure is below necessary standard
so

slow flow of blood to organs

so

inadequate perfusion of tissue for cellular metabolic requirements

Question 10

how might you recognise shock

Answer 10

altered mental state
GCS <15

skin is cmally/mottled

oligura

Question 11

will lactate increase of decrease in shock

Answer 11

increase

more anaerobic respiration
