Shock Lecture Notes

Vocabulary flashcards based on lecture notes about shock

Shock

A momentary pause in the act of death.

Shock

The manifestation of the rude unhinging of the machinery of life.

Perfusion

Circulation of blood through different organs and tissues.

Hypoperfusion

Inadequate Flow.

Pathophysiology of shock

Reduced perfusion, neuroendocrine response, cytokine response, redistribution of flow to vital organs, ischemia of non-vital organs, flow maldistribution within organs, dysoxia & multiple organ failure.

Compensated shock

Perfusion maintained.

Decompensated shock

Cellular hypoxia.

Irreversible shock

End organ failure.

Hypovolemic shock

Diminished blood volume.

Cardiogenic shock

Inefficient myocardial function.

Neurogenic shock

Peripheral vasodilatation leading to decreased resistance and increased pooling.

Anaphylactic shock

Antigen-antibody reaction leading to rupture of mast cells and the release of histamine, causing widespread vasodilatation.

Septic shock

Severe bacterial sepsis leading to toxins.
