Inability to maintain adequate blood flow through peripheral tissues and arterial blood pressure.

=== Cause: ===

* The imbalance between the volume of blood and the volume of the vascular bed caused by:
** reduced blood volume ([[hypovolemic shock]], cold shock)
** by increasing the capacity of the vascular bed ([[distributive shock]], warm shock)

; <nowiki>Hypovolemic shock:</nowiki>

* [[Hemorrhage]]
* Burns (hematocrit, toxins, pain)
* [[Dehydration]] (AB balance)

; <nowiki>Distribution shock:</nowiki>

* [[Anaphylaxis]] (bronchoconstriction)
* [[Sepsis]] (fever, toxins)
* Neurogenic vasodilation

=== The shock phase: ===

* initial (activation of compensatory mechanisms)
* Progressive (failure of compensatory mechanisms)

=== Consequences: ===

* Tissue ischemia and microcirculation
* Consequences of damage to individual organs

=== Treatment: ===

* Maintaining the volume of circulating fluid
* Sympathomimetics
* [[Corticosteroids]]
