Cardiogenic Shock INCREASED SVR, INCREASED CVP/PAP/PAWP =
FLUID OVERLOAD
- narrow pulse pressure
- decreased B/P & CO
- increased HR & RR


Hypovalemic Shock DECREASED CVP/PAP/PAWP = FLUID DEPLETED
- decreased B/P & CO
- increased HR, RR, SVR (vasoconstriction d/t low B/P)


Septic Shock INCREASED CO = VASODILATE = WARM & FLUSHED
- decreased B/P, SVR, CVP/PAP/PAWP
- increased HR & RR

, Anaphylactic Shock - decreased B/P, CO, SVR, CVP/PAP/PAWP
- increased HR, RR


Neurogenic Shock DECREASED HR = BRADYCARDIA
- decreased B/P, CO, SVR, CVP/PAP/PAWP


Compensatory Stage *decreased CO, B/P
*increased SVR, RAS, ADH, ALDOSTERONE
- some shunting of blood to the brain and the heart
*pale, cool, decreased LOC
- restless, anxious, mydriasis
- increased HR, RR
respiratory alkalosis ( increased PH, decreased CO2)
*vasoconstriction
GI tract (impaired, slow)


Organs in Shock 1st to go = lungs
2nd to go = kindeys


Progressive Stage lungs 1st to go
*decreased
responsiveness/delirium/pale/cool/clammy
- multiorgan involvement
*increased capillary permeability = 3rd spacing
- shunting of blood to brain and heart
*lungs = tachypnea, crackles, increased work of
breathing
- GI ischemia, ulcers, bleeding, increased bacteria
- AKI = metabolic acidosis
- liver failure = increased ammonia
- DIC = systemic failure
