The flashcards below were created by user kbryant86 on FreezingBlue Flashcards. What would you like to do?


  1. initial stage
    • minor hypoperfus
    • dec ts O2tion
    • mild rise in lac acid
    • no real sx yet
  2. compensatory stage
    • compen mechs activated by dec CO and BP
    • RASS and ADH kick in

    • Sx= fatigue (dec ATP prod)
    •  =inc HR and RR
    •  =narrowed pulse pressure with dec BP
    •  =mild anxiety
    •  =dec UO
    •  =inc lactic
  3. Progressive stage
    • comp mechs failing
    • ts dammage occurs
    • dec ATP prod
    • Sx= dysrrhythmias
    •  =INC HR and RR
    •  =DEC BP
    •  =lethargy
    •  =cold and clammu
    •  =anuria
    •  =dec CO=CI
  4. Refract stage
    death is inevitable

    severe hypoTN, metab acidosis, dysrrhytmias (vTac-Fib), coma, oragan failure
  5. what to do right away?
    • give O2
    • bed rest to dec O2 demand
    • Tx pain and give fluids

    trendelunberg position can be used
  6. hypovolemic shock

    common cx's
    dec in circulating bld volume

    cx= bld loss, plasma loss (bowel obtruction), dehydration
  7. dec volume means decreased CO and dec perfusion
  8. hemodyn findings of hypo volume:
    HR
    preload
    Co
    Afterload
    SvO2
    • HR= inc b/c dec SV
    • preload= dec b/c dec volume
    • CO= dec
    • after= inc which is helpful in shock
    • O2= low nl to dec
  9. Tx of hypovolemia
    • Tx underlying cx
    • give fluids
    • vasopresoors
  10. cardiogenic shock

    Cx's
    due to imparied pumping ability

    • Cxs= ventricular ischemia from Anterior wall MI
    •  =structural problems (valve disease)
    •  =dyrrhythmias
  11. hemodyn findings of cardio:
    HR
    preload
    Co
    Afterload
    SvO2
    • HR=inc
    • pre= inc (PAWP inc too)
    • CO= dec  (CI <1.8 is Sx of cardioshock)
    • afterload= inc (not helful!)
    • O2= dec
  12. prevention measures for cardio shock
    • limit myocardio damage
    • thrombolytics
    • angioplasty
    • CABG
  13. Tx of cardio shock
    • Tx underlying cx
    • improve heart pumping ability
    • improve ts perfusion
    • decrease anxiety and SOB w/ MORPHINE
    • + inotropes to inc contract
    • diuretics to dec preload
    • nipride to dec afterload
  14. intra-aortic balloon pump
    • increases coronary perfusion
    • dec afterload
    • inc SV and CO

    • inflates in diastole
    • deflates on systole
  15. impella device
    temp motor sitting in L vent via arota
  16. Distributive shock

    3 types and what differs?
    due to vasodilation

    • types:
    • neurogenic (spinal)
    • anaphylatic
    • septic

    initiating event differs
  17. vasodilation will dec venous return, SV, CO, and therefore ts perfusion
  18. nuerogenic shock
    • least common shock
    • resluts from loss of supression of sympathetic tone
    • (disruption of SNS and PNS takes over)

    • cx's:
    • high spnal injury
    • high spinal anesthesia
    • severe pain
  19. vasodilation = loss of symp tone
    PNS dominates dec'ing BP
    dilation dec ts perfusion
  20. hemo findings of nuero shock:
    HR
    preload
    Co
    Afterload
    SvO2
    Temp
    • HR= dec
    • preload=dec b/c dilation
    • CO=dec b/c dec v return
    • after= dec b/c dilation
    • O2= dec
    • temp may dec d/t heat loss
  21. Tx of nuero shock
    • Tx underlying cx, stablize spine
    • Atropine for bradycardia
    • possible vasopressor like ADH
    • very careful fluid corrections
  22. anaphylactic shock
    • cx's by immediate hypersense rxn
    • IgE mediated
    • antigen-antibody rxn
    • mast cells are stimulated
  23. AnaphylactOID rxn
    • NON- IgE mediated
    • Direct stimulation of Mast cells
    • common with Nsaids
  24. trigger of mast cells
    histamine released
    dilation
    inc cap perm
    constriction of smooth muscle (broncho constrict)
  25. clinical presentation of anaphylact
    • feel warm, hives
    • angioedema
    • severe resp distress from swollen throat
    • anxiety
    • DEC BP and dec LOC
    • DEATH MAY OCCUR
  26. Hemo finsings of ana shock:
    HR
    Preload
    CO
    Afterload
    SvO2
    • HR= inc
    • Pre= dec (dilation)
    • CO= dec
    • Afer= dec
    • O2= dec
  27. Tx and anaphylact
    • Epi pen
    • antihistamine
    • bronchoDilator
    • corticosteroids

    IV fluids and vasopressor if sever rxn
