Chapter 18 - Shock

Hypoperfusion

Shock.

Decompensated Shock

The condition in which the body is no longer able to compensate for a lack of adequate perfusion.

Fainting

Psychogenic shock. Most often self-correcting.

Perfusion

The adequate supply of well-oxygenated blood and nutrients to all vital organs.

Compensated Shock

The condition in which the body is using specific mechanisms, such as increased pulse rate and increased breathing rate, to compensate for a lack of adequate perfusion.

Shock

The failure of the body's circulatory system to provide an adequate supply of well-oxygenated blood and nutrients to all vital organs.

Pump Failure

Cardiogenic Shock

Hypovolemic Shock

A category of shock caused by an abnormally low fluid volume in the body.

Obstructive Shock

A category of shock caused when an obstruction of a vessel causes less blood to be pumped by the heart.

Distributive Shock

A category or shock when the vessels dilate excessively resulting in a much larger space than the available blood supply can fill.

Anaphylactic Shock

A form of Distributive shock caused by a severe allergic reaction.

Septic Shock

A form of Distributive shock caused by a widespread infection of the blood.

Neurogenic Shock

A form of Distributive shock resulting from a spinal-cord injury.ds

Psychogenic Shock

A form of Distributive shock that results in a sudden, temporary dilation of the blood vessels.

Hemorrhagic Shock

A form of Hypovolemic shock that occurs when the body loses a significant amount of blood.

Resperatory/Metabolic Shock

A form of shock caused by the disruption of the transfer of oxygen into the cells or the ability of the cells to utilize oxygen.

Hypotension

Abnormally low blood pressure.

Cardiogenic Shock

Both a category and type of shock where the heart fails to pump an adequate volume of oxygenated blood.
