Introduction

Shock is a condition in which there is inadequate blood supply to tissue of the body.

It is also defined a generalized hypoperfusion.

In other words it is lack of supply of oxygen to the body as demanded by the tissue. 

Types of Shock

1. Cardiogenic
2. Obstructive
3. Hypovolemic
4. Distributive
1. Septic
2. Anaphylactic
3. Neurogenic

Cardiogenic Shock

What happens:

Heart fails to pump blood out 

Eg: 

MI, Arrhythmia, aortic stenosis, mitral regurgitation

Effect: 

decreaded cardiac output

Compensated by: 

Baroreceptors, Increased systemic vascular resistance

Obstructive Shock

What happens:

Heart pumps well but outflow is obstructed  to pump blood out 

Eg: 

Pulmonary embolism, tension pneumothorax, pericardiac temponade, large pleural effusions etc

Effect: 

decreaded cardiac output

Compensated by: 

Baroreceptors, Increased systemic vascular resistance

In other words it is lack of supply of oxygen to the body as demanded by the tissue. 

Hypovolemic Shock

What happens:

Heart pumps blood out well but there not enough blood/ blood volume to be pumped

 

Eg: 

Hemorrhage, fluid loss due to diarrhea, burns, decreased intake, or due to conditions that lose fluid, diuretics overdose etc

Effect: 

decreaded cardiac output

Compensated by: 

Baroreceptors, Increased systemic vascular resistance

Distributive Shock

What happens:

Heart pump blood out well enough but the peripheral vessels are dilated (vasodilation)

Eg: 

Three main subtypes viz. septic, anaphylactic and neurogenic

SIRS due to noinfective inflammation including pancreatitis, burns, poly/multitrauma which activates inflammatory response

Effect: 

decreaded systemic vascular resistance

Compensated by: 

increaded cardiac output
