Shock is defined as decrease in the oxygen delivery to the cells and tissues due to either increase in oxygen demand, decrease in oxygen consumption, inadequate oxygen utilization or a combination of these processes.

*Distributive shock can be from [[Septic Shock]], [[Systemic inflammatory response syndrome]], endocrine, toxin and drug induced, [[Anaphylactic shock]] and [[Neurogenic shock]].
*Obstructive shock can be mechanical, [[pulmonary]] or [[Vascular]] causes.
*Cardiogenic shock can be from [[Cardiomyopathies|cardiomyopathy]], [[Arryhthmias]] or mechanical.
*Hypovolemic shock can be [[hemorrhagic]] or non -hemorrhagic.

Shock

OVERVIEW

HISTORICAL PERSPECTIVE:

  • There is limited historical perspective for shock.

Definition:

Shock is defined as decrease in the oxygen delivery to the cells and tissues due to either increase in oxygen demand, decrease in oxygen consumption, inadequate oxygen utilization or a combination of these processes.

Classification:

  • Distributive shock
  • Obstructive shock
  • cardiogenic shock
  • Hypovolemic shock

Causes:

Pathophysiology:
