Causes
Life Threatening Causes
Shock is a life-threatening condition and must be treated as such irrespective of the underlying cause.
Common Causes
- Cardiogenic shock
- Arrhythmic
- Mechanical
- Myocardial
- Pharmacologic
- Obstructive shock
- Decreased cardiac compliance
- Decreased ventricular preload
- Increased ventricular afterload
- Hypovolemic shock
- Fluid depletion
- Hemorrhage
- Distributive shock
- Sepsis
- Toxic shock syndrome
- Anaphylactic or anaphylactoid reaction
- Neurogenic shock
- Endocrinologic
