1

What are the different types of shock?

Cardiogenic
Mechanical
Hypovalaemic
Distributive (septic & anaphylaxis)

2

Define Shock

Acute circulatory failure with either inadequate or inappropriately distributed tissue perfusion, resulting in generalised lack of oxygen supply to cells

3

What is Cardiogenic shock?

The heart is unable to eject enough blood

4

When can Cardiogenic shock occur?

In arrhythmias
Ischaemic cardiac damage

5

When can mechanical shock occur?

There is restriction on filling of the heart (eg cardiac tamponade)
Obstruction to blood flow through the lungs (eg PE)

6

What is Hypovalaemic shock?

Loss of fluid circulating volume

7

When can Hypovalaemic shock occur?

In a haemorrhage

8

How can you treat Hypovalaemic shock?

Infuse fluid with high protein content

9

How can you treat mechanical shock caused by cardiac tamponade?

Drain the pericardial sac

10

What are the 2 types of distributive shock?

Septic
Anaphylactic

11

What causes distributive shock?

Uncontrolled falls in peripheral resistance

12

How can sepsis lead to distributive shock?

Endotoxins released which cause increase vasodilation

13

How can you treat sepsis?

Adrenaline and antibiotics

14

What causes Analphylactic shock?

Release of Histamine from Mast cells causes vasodilation

15

How can you treat anaphylaxis?

Adrenaline
