What is shock? Shock is a life-threatening situation where the body doesn't have enough blood flow, which means cells and tissue don't receive oxygen which can lead to multiple organ failure. This video covers the pathophysiology surrounding the major forms of shock, including hypovolemic, cardiogenic, and distributive shock, as well as several subcategories like septic shock.

  • around 7:34- 8:22 - if we have microvasculature blockage - doesn't this increase resistance and therefore make it harder for blood to move around the body? If not why? Is it because blood gets shunted away from the capillaries via collaterals? and I'm assuming this has the added benefit of bypassing tissue perfusion?

  • They never teach me like this during my college time, i spent 48 month in college, but here just 10min i learned a lot. My point is why should i spend my time for 4years in college if there's a way just only 24hrs i already finished my medical degree in college. It could be a lot of money that i saved in my bank account .

  • Ischemia: lack of blood flow to tissue (circulatory failure) --> lack of oxygen and nutrition --> cellular damage --> organ failure Shock: body-scale ischemia --> multiple organ failure Blood pressure determines perfusion of oxygen and nutrition to tissue Blood pressure = resistance x cardiac output = resistance x (heart rate x stroke volume) = resistance x heart rate x (end diastolic volume - end systolic volume) : low cardiac output --> low blood pressure --> low perfusion + Low blood flow --> low tissue's heat --> cool and clammy skin + Low mixed venous oxygen saturation Regulation (goal: normal perfusion): low cardiac output --> release of catecholamines, ADH and angiotensin II --> vasoconstriction --> increases resistance and heart rate --> increase blood pressure (low-volume-blood) SHOCK 1. Non-hemorrhagic (not-from-bleeding) --> occurs when suffering severe dehydration --> low blood volume --> low stroke volume --> ... 2. Hemorrhagic (from-bleeding): starts when loss of about 1 liter of blood (20%) --> low blood volume --> low stroke volume --> ... (heart-produced-by) SHOCK Trauma (usually heart attack) --> damage of heart muscle cell --> weak contraction --> low stroke volume --> ... Obstruction in heart (fluid or blood in pericardial sac) --> constriction of heart muscle from expanding --> low stroke volume --> ... : low resistance --> low blood pressure --> low distribution to (some) tissues + High blood flow --> high tissue's heat --> warm and flushed skin + Normal or high mixed venous oxygen saturation SHOCK: caused by leaky blood vessels or excessive vasodilation 2 subtypes: anaphylactic shock (allergic reaction) and neurogenic shock (damage of CNS --> can't control blood pressure) Most common: SHOCK (from pathogens in blood): endotoxins --> low perfusion --> direct damage of endothelial cells --> release of vasodilators --> activation of complement pathway --> activation of mast cells --> release of histamine (vasodilator) Pathogens --> activation of macrophages and neutrophils --> release of cytokines --> release of inflammatory molecules by endothelial cells --> damage of endothelial cells (again!) --> leaky blood vessel and more blood clotting --> low perfusion (more!) TREATMENT Goal: stabilize blood pressure --> vital organs can be perfused with blood --> fluid replacement and medications Often: supplemental oxygen and airway protection
