Show Answers:

  1. Causes of Shock
    • 1. Pump Failure
    • Cardiogenic Shock
    • Obstructive Shock

    • 2. Poor Vessel Function
    • Distributive Shock
    • Septic
    • Neurogenic
    • Anaphylactic
    • Psychogenic

    • 3. Low Fluid Volume
    • Hypovolemic Shock
    • Hemorrhagic
    • Nonhemorrhagic
  2. Types of Pump Failure Shock
    • 1. Cardiogenic-Inadequate heart function, Disease of muscle tissue, impaired electrical system, Disease or injury.
    • Would Present w/ Chest Pain, Irregular Pulse, Low BP, Cyanosis, Cool Clammy Skin, ETC.

    2. Obstructive- Mechanical obstruction of the cardiac muscle (Tension Pneumothorax or Cardiac Tamponade) Would Present-Dyspnea, Rapid weak pulse, JVD, ETC
  3. Types of Poor Vessel Function Shock
    1. Septic- Severe bacterial infection. Would present with-Warm Skin, Tachycardia, Low BP

    2. Neurogenic- Damaged C-Spine which causes wide-spread blood vessel dilation. Would Present With-Bradycardia, low BP, Signs of neck injury

    3. Anaphylactic- Extreme life-threatening allergic reaction. Would Present With-mild itching or rash, buring skin, vascular dilation, generalized edema, coma, rapid death.

    4. Psychogenic- Temporary generalized vascular dilation, anxiety, bad news, sight of injury or blood, severe pain, illness. Would Present With- Rapid Pulse, Normal to low BP
  4. Types of Low Fluid Volume Shock
    1. Hypovolemic- Loss of blood or fluid. Would Present With- Rapid weak pulse, Low BP, Change in mental status, cool clammy skin, increased RR.

    2. Respiratory Insufficiency- Severe chest injury, airway obstruction. Would Present With- Rapid weak pulse, low BP, Change in mental status, cool clammy skin, increased RR.
  5. What is the Progression of Shock
    1. Compensated Shock-When the body can still compensate for blood loss. Presents with: Agitation, anxiety, feeling of impending doom, clammy pale skin, nausea or vomiting, ETC.

    2. Decompensated Shock- The late stage when BP is falling. 90mm Hg below in adults, labored/irregular breathing, cyanotic skin, thready absent pulses, poor urinary output.

    3. Irreversible Shock- This is the last stage, the terminal stage where nothing will help.
  6. What is Shock?
    Shock results from the body's maintenance of homeostasis.
