Definition
Causes
Life Threatening Causes
Common Causes
- Cardiogenic shock
- Pump problems (e.g. post-MI), cardiomyopathy
- Mechanical (e.g. cardiac tamponade, tension pneumothorax), aortic stenosis
- Electrical eg VT or AF or most fundamentally VF
- Hypovolemic shock
- True hypovolemia
- Bleeding i.e hemorrhagic shock
- Fluid loss (e.g. diarrhoea, vomiting, bowel obstruction, 'third' spacing)
- Redistributive hypovolemia
