1. Shock inadequate tissue perfusion resulting in cellular dysfunction
2. Stages of shock compensatory
progressive
refractory
3. Compensatory decrease in CO
stage of shock sympathetic nervous system to release adrenalin to increase CO, BP, ADH (kidney's
hold onto h20) vasoconstriction
4. progressive when compensatory mechanisms fail. organ functions begin to deteriorate
stage of shock
5. refractory stage This stage of shock is irreversible. Severe acidosis and organ failure occur. Cell
of shock death and tissue damage occurs from too little O2 reaching the tissues. There is
no response to fluids or vasopressors, and multiple organ failure results.
6. anaerobic metab- leads to an acidic environment - high hydrogen ions and lactate
olism
7. Hypovolemic crystalloids or colloids
shock fluid
resuscitation NS can be infused rapidly but can lead to acidosis and fluid overload
LR need to consider hyperkalemia
albumin - good volume expander but more expensive and can cause an allergic
reaction
blood products - reserve for actively bleeding patient
8. Hypovolemic shock resulting from blood or fluid loss
shock
decrease preload and stroke volume = decrease in cardiac output

9. Hypo shock cate- II - loss 15-30% mild symptoms
gories III - 30-40% moderate symptoms
IV - >40% severe symptoms/shock
10. SBP in hypov- SBP cannot always be a good indicator of shock....can compesate for up to 30%
olemic shock loss
11. Hypovolemic Fluid resuscitation
Shock Treatment Blood products - Hgb <7
Crystalloids
Colloids
vasopressors or inotropes - must have volume though
Recombinant factor VIIa - promotes hemostasis (off label use), when other strate-
gies fail
Airway management - ABC's first
12. Hypovolemic CO/CI: LOW
Shock CVP: LOW
Hemodynamics PCWP: LOW
SVR: High - attemping to compensate
SVO2: LOW
13. Cardiogenic Shock caused by inadequate function of the heart, or pump failure.

14. Cardiogenic -Myocardial infarction (MC)
shock causes -Cardiomyopathy
-Valve disorders
-Arrhythmia
-PE
-Pulmonary HTN
-End stage cardiomyopathy
