Describing shock.

Classification of shock	Description
Compensated shock or impaired circulation	The early phase of shock in which the body’s compensatory mechanisms (such as increased heart rate, vasoconstriction, increased respiratory rate) are able to maintain adequate perfusion to the brain and vital organs. Typically, the patient is normotensive in compensated shock [75]
Decompensated shock or severely impaired circulation	The late phase of shock in which the body’s compensatory mechanisms (such as increased heart rate, vasoconstriction, increased respiratory rate) are unable to maintain adequate perfusion to the brain and vital organs. Typically, the patient is hypotensive in decompensated shock [75]
