  1. The medical term for shock
  2. Who do we treat for shock?
    all victims
  3. 2 causes of shock
    • 1. cardiovascular (heart, vessels, blood)
    • 2. noncardiovascular
  4. A state of collapse and failure of the cardiovascular system in which blood circulation decreases and eventually ceases. Can be anything from a heart attack-allergic reaction.
    Shock (hypoperfusion)
  5. Circulatory system has 3 components:
    • 1. a working pump-HEART
    • 2. a network of pipes-BLOOD VESSELS
    • 3. an adequate amount of fluid-BLOOD
    • *these 3 can be referred to as the PERFUSION TRIANGLE*
  6. 4 types of shock in cardiovascular
    • 1. Cardiogenic shock
    • 2. Hypovolemic shock/ Hemorrhagic shock
    • 3. Neurogenic shock
    • 4. Septic shock
  7. Caused by inadequate function of the heart, or pump failure (heart attack, backup of blood into the lungs-pulmonary edema)
    Cardiogenic shock
  8. Loss of fluid or blood, insufficient VOLUME of blood; can be internal or external bleeding; can occur with severe thermal burns (loss of plasma or dehydration)
    Hypovolemic shock
  9. Spinal cord damage can injure the part of the nervous system that controls blood vessel size and muscle tone, this is example of what kind of shock
    Neurogenic shock
  10. Victims who have severe backterial infections that produce toxins/poisons which cause widespread vessel dilation, combined with the loss of plasma through injured vessel walls (this shock is almost always a commplication of a serious illness, injury, or surgery, and anaphylaxis)
    Septic shock
  11. 3 noncardiovascular causes of shock
    • 1. Respiratory insufficiency
    • 2. Anaphlactic shock/ Anaphylaxis
    • 3. Psychogenic shock
  12. Chest injury or airway obstruction that results in INSUFFICIENT OXYGEN in the blood can produce shock
    Respiratory insufficiency
  13. Occurs when the immune system reacts violently to a sub to which it has already been sensitized; sever alergic reaction; signs of this kind of shock are distinct from other forms of shock.
    Anaphylactic shock/ Anaphylaxis
  14. Severe allergic reactions commonly follow exposure by one of the these:
    • 1. Medications (penicillin, aspirin, sulfa drugs)
    • 2. Food (shellfish, nuts, eggs)
    • 3. Insect stings (honeybee, wasp, yellow jacket, hornet, fire ant)

    • *Wheezing (forced expirations during breathing)
    • *Breathing stops
  16. A sudden nervous system reaction that produces a temporary vascular dilation, resulting in fainting, or syncope (causes can range from fear, bad news, or unpleasant sights)
    Psychogenic shock

  20. How do you care for Anaphylaxis?
    Immediately call 9-1-1. Use epi pen (epinephrine auto-injector) or benedryl
  21. How much blood does an adult have and how much can they lose before going into shock?
    • Adult has 5-6 quarts (10-12 pints)
    • *dangerous amount is 1quart in an adult and a child can only lose 1 pint.
  22. 3 Types of bleeding; according to the type of blood vessel that is damaged.
    • 1. Arterial bleeding
    • 2. Venous bleeding
    • 3. Capillary bleeding
  23. Refers to a large amount of bleeding in a short time
  24. The most serious type of bleeding because a large amount of blood can be lost in a very short period of time; less likely to clot bc blood can clot only when it is flowing slowly; dangerous and difficult to control
    Arterial bleeding
  25. Blood from a vein flows steadily or gushes; bleeding from the veins
    Venous bleeding
  26. The most common type of bleeding, blood oozes from the capillaries; usually not serious and can be controlled easily; will usually clot and stop by itself
    Capillary bleeding
  27. Two ways the body naturally responds to bleeding
    • 1. Blood vessel spasm

    • 4. If bleeding from an extremity (arms or legs) elevate and apply pressure
    • 5. To free you to attend to other injuries or victims, use a pressure bandage to hold the dressing on the wound. (Use a roller gauze bandage)
    • 6. If the bleeding continues, apply pressure at a pressure point to slow the flow of blood as you continue putting direct pressure over the wound.
    • 7. If direct pressure can't be applied due to protruding bone or object, make a doughnut shaped pad to control bleeding.

    • E -Elevate the injured extremity
  32. The top layer of the skin is removed, with little or no blood loss; tend to be painful bc the nerve endings often go along with the skin
  33. Cut skin with jagged, irregular edges; usually caused by a forceful tearing away of skin tissue
  34. Ten to have smooth edges and resemble a surgical or paper cut; the amount of bleeding has to do with the depth, the location, and the size of the wound
  35. Are usually deep, narrow wounds in the skin and underlying organs such as a stab wound from a nail or knife; the entrance is usually small, and the risk of infection is high
  36. A piece of skin is torn loose and is hanging from the body or completely removed; can bleed heavily; if the flap is still attached, lay it flat and realign it into its normal position; often involve ears, fingers, and hands
  37. Involves the cutting or tearing off of a body part, such as a finger, toe, hand, foot, arm, or leg
  38. Care for open wounds
    • 1. Protect yourself (gloves)
    • 2. Expose the wound (move clothing)
    • 3. Control the bleeding by using direct pressure. If direct pressure doesn't resolve it elevate and use pressure points.
  39. What usually restarts the bleeding bc it disturbs the clot?
    Wound cleaning
  40. Cleaning a wound
    • 1. Scrub your hands with soap and warm water
    • 2. Expose the wound
    • 3. Clean the wound

    • Chemical burns
    • 1. acids
    • 2. alkalis- produce deeper, more extensive burns than acids
    • 3. organic compounds
  69. The injury severity from contact with electric current depends on the type of current, the voltage, the area of the body exposed, and the duration of contact. can cause cardiac arrest (Ventricular fibrillation)
    Electrical burns
  71. Affect the skin's OUTER layer (epidermis). Characteristics include rudeness, mild swelling, tenderness, and pain; healing occurs without scarring within a week.
    1st degree burn SUPERFICIAL
  72. Extend through the entire outer later and into the inner skin layer. blisters, swelling, weeping of fluids, and severe pain characterize these burns, which occur bc the capillary blood vessels in the dermis are damaged and give up fluid into surrounding tissues.
    2nd degree burns PARTIAL-THICKNESS
  73. Severe burns that penetrate all the skin layers into the underlying fat and muscle. the skin looks leathery, waxy, or perly gray and sometimes charred. dry appearance. victim feels no pain bc the nerve endings have been damaged or destroyed; usually involes skin graft

    Thermal burn (flame)
  83. Occurs when electricity jumps, or arcs, from one spot to another and not from the passage of an electric current through the body; causes extensive superficial injuries
    Arc burn (flash)
  84. Happens when an electric current passes directly through the body; characterized by the entrance wound and an exit wound; the surface injury isnt the only concern may have cardiac arrest or internal burns and other injuries
    True electrical injury (contact)
  85. Care for electrical burns
