  1. What are the six types of Shock?
    • Cardiogenic
    • Septic
    • Hypovolemic
    • Neurogenic
    • Anaphylactic
  2. What are the three phases of Shock
    • Compensatory
    • Progressive
    • Irreversible
  3. What do the Chemoreceptors do?
    • Respond to changes in O2 in blood
    • Control cardiac output
  4. What are the three compensatory mechanisms
    • Increase respiratory rate, tidal volume and Cardiac output
    • Kidneys activate the Renin-Angiotensin system due to decreased blood flow
    • Brain releases anti-diuretic hormone
  5. What is the "Classic" sign of hypovomic shock
    Decreased urine output
  6. What would we expect to see in on the ABG of a shock patient
    • Acidosis
    • electrolyte imbalances
  7. What percentage of MI patients develop Cardiogenic shock?
    20-40%
  8. What percent of infarcted tissue in the L ventricle will cause cardiogenic shock?
    40%
  9. What are the treatment priorities for Cardiogenic Shock?
    • Rate
    • Rhythm
    • BP (Volume, Pump/Vascular tone)
    • Improve oxygenation
  10. Two causes of Pulmonary Edema?
    • Pump
    • Volume
  11. How do you treat Pulmonary Edema?
    • IV/O2/Monitor
    • Volume-
    • Fluid Challenge
    • Vasopressors
    • Pump-
    • Norepinephrine 0.5-30 mcg/min
    • Dopamine 5-15 mcg/kg/min
  12. What causes Septic Shock?
    • Severe infection causing blood to pool
    • Usually bacterial,but may be caused from virus, fungal, rickettsial infection
  13. Treatment for Septic Shock includes what?
    • Antibiotics
    • Large amounts of fluid
    • Dopamine
    • Respiratory support
    • Drain abscesses/replace catheters
  14. How much volume loss is needed to see hypovolemia?
    15-20% (500ml-1500ml)
  15. Class I Hemorrhage
    0-15% loss
  16. Class II Hemorrhage
    15-30% loss
  17. Class III Hemorrhage
    30-40% loss
  18. Class IV Hemorrhage
    >40% loss
  19. What are the four areas a life-threatening hemorrhage can occur?
    • Chest
    • Abdomen
    • Thighs
    • Outside the body
  20. What is the treatment for hemorrhagic shock?
    • Maximize O2 delivery
    • Control further bleeding
    • Fluid resuscitation
  21. What is the main precaution with fluid resuscitation?
    Hypothermia
  22. What is the treatment of choice for Anaphlyaxis?
    Epinephrine 1:1,000
  23. What causes Neurogenic Shock
    An injury or insult to the Reticular Activating System (RAS) and spinal cord
  24. What precaution should be considered prior to administering vasoconstrictive drugs to a shock patient?
    Ensure volume is adequately restored.
  25. What are the indications to administering Solu-Medrol in neurogenic shock?
    <8 hours post injury
  26. What is the dosage of Solumedrol for a spinal injury?
    • 30 mg/kg over 15 minutes
    • Followed by a maintenance infusion of 5.4 mg/kg over the next 23 hours
  27. How do you calculate MAP?
    • 1-2-3 Method
    • 1 systolic + 2 diastolic / 3
  28. What should the MAP be maintained at?
