4 types/Tx
4 types
- Cardiac temponade
- Tension, Pnuemothorax
- Aortic dissection
- PE
Tx: underlying cause
General circulatory shock
Patho/Lab/Tx
Patho (lack of O2 in tissue and orgran )
- Autonomic - loss of O2 -> increase CO and SVR to maintain
- lack of O2 -> anareobic metabolic -> by product lactic acid
Lab: CBC, BMP, Lactate
Tx: ABCDE
Airway(intubation)
Breath (ventilation)
Circulation (IV fluid)
Delivary O2 check - lactate level

Syncope + healthy young man without any health problem + NO exp of post ictal status, bladder/bowel incontinence
Name/Patho/cause
Name: Vasovagal hypotension
Patho: due to systemic hypotension cause loss of conciousness
Cause: prolong standing, heat exhaust, fear, blood draw
Most of case not dangerous
- HTN + DM =
