Shock occurs when the tissues or organs of the body are inadequately
supplied with oxygenated blood.
Types of Shock:
Loss of fluid from bleeding, sweating, vomiting, diarrhea and/or severe burns.
Failure of the heart to adequately pump blood.
Loss of vascular tone resulting in an increased vascular space.
( Spinal Cord Injury, Sepsis, Anaphylaxis)
Stages of Shock:
Peripheral vasoconstriction, increased HR and increased
respiratory rate to keep blood pressure within normal
limits to maintain adequate perfusion pressure.
Blood pressure starts to drop and inadequate perfusion begins
Organs begin to die from inadequate perfusion
