What is shock?
• Inadequate tissue perfusion resulting in
impaired cellular metabolism o Deprives cells
of essential oxygen and nutrients, forcing cells
to rely on anaerobic (without oxygen)
metabolism
• Less energy is produced
• Lactic acid causes tissue acidosis and
subsequent organ dysfunction
Types of Shock
• Hypovolemic
o Inadequate blood volume to maintain the
supply of oxygen and nutrients to body
tissues
o Intravascular or circulating volume deficits
can occur from external or internal losses
o Blood volume falls with excessive blood or
fluid loss, inadequate fluid intake, or a
shift of plasma from the blood vessels into
body tissues/ organs o Causes of
blood/fluid loss: hemorrhage, severe
diarrhea Or vomiting, excessive
perspiration
, lOMoARcPSD|57630370
o Excessive shift of plasma with pathologic
states (burns, peritonitis, and intestinal
obstruction)
• Cardiogenic o Occurs when heart fails as a
pump o Decreased myocardial contractility
causes decreased cardiac output and impaired
tissue perfusion
o Difficult to treat and usually results when
diseased coronary arteries cannot meet
the demand of the working myocardial
cells
• Causes include conditions that result in
ineffective myocardial cell function, such as:
o Dysrhythmias o Cardiomyopathy o
Myocarditis o Valvular disease o
Structural disorders
• Obstructive o Physical impairment of adequate
circulating blood flow
o Obstruction of the heart or great vessels
either blocks venous return to the right
