1
Q

what is shock?

A

clinical syndrome of tissue hypoperfusion due to circulatory failure

2
Q

what happens in cardiogenic shock>

A

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

3
Q

name some causes of cardiogenic shock

A

ischaemia

valve disease

4
Q

what happens in obstructive shock

A

there is obstruction to cardiac outflow

get venous back pressure causine

RAISED JVP AND DISTENDED NECK VEINS

5
Q

name some causes of obstructive shock

A

PE

tension pneumothorax

6
Q

what happens in hypovolaemic shock

A

there is decreased blood volume

lover venous return to heart

reduced force of contraction and reduced cardiac output

7
Q

name some causes of hypovolaemic shock

A

dehydration

haemorrhage

8
Q

what happens in disruptive shock

A

decreased systemic vascular resistance due to vasodilation

Decreased MAP and compensatory increase in cardiac output

WARM RED PERIPHERIES

9
Q

describe the basic pathophysiology of shock

A

mean arterial pressure is below necessary standard
so

slow flow of blood to organs

so

inadequate perfusion of tissue for cellular metabolic requirements

10
Q

how might you recognise shock

A

altered mental state
GCS <15

skin is cmally/mottled

oligura

11
Q

will lactate increase of decrease in shock

A

increase

more anaerobic respiration
