What are the six types of Shock?
What are the three phases of Shock
What do the Chemoreceptors do?
- Respond to changes in O2 in blood
- Control cardiac output
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
What is the "Classic" sign of hypovomic shock
Decreased urine output
What would we expect to see in on the ABG of a shock patient
- electrolyte imbalances
What percentage of MI patients develop Cardiogenic shock?
What percent of infarcted tissue in the L ventricle will cause cardiogenic shock?
What are the treatment priorities for Cardiogenic Shock?
- BP (Volume, Pump/Vascular tone)
- Improve oxygenation
Two causes of Pulmonary Edema?
How do you treat Pulmonary Edema?
- Fluid Challenge
- Norepinephrine 0.5-30 mcg/min
- Dopamine 5-15 mcg/kg/min
What causes Septic Shock?
- Severe infection causing blood to pool
- Usually bacterial,but may be caused from virus, fungal, rickettsial infection
Treatment for Septic Shock includes what?
- Large amounts of fluid
- Respiratory support
- Drain abscesses/replace catheters
How much volume loss is needed to see hypovolemia?
Class I Hemorrhage
Class II Hemorrhage
Class III Hemorrhage
Class IV Hemorrhage
What are the four areas a life-threatening hemorrhage can occur?
- Outside the body
What is the treatment for hemorrhagic shock?
- Maximize O2 delivery
- Control further bleeding
- Fluid resuscitation
What is the main precaution with fluid resuscitation?
What is the treatment of choice for Anaphlyaxis?
What causes Neurogenic Shock
An injury or insult to the Reticular Activating System (RAS) and spinal cord
What precaution should be considered prior to administering vasoconstrictive drugs to a shock patient?
Ensure volume is adequately restored.
What are the indications to administering Solu-Medrol in neurogenic shock?
<8 hours post injury
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
How do you calculate MAP?
- 1-2-3 Method
- 1 systolic + 2 diastolic / 3
What should the MAP be maintained at?
