15.4 Providing First Aid for Shock Pages 403-405 LEQ: When caring for a shock victim, how does the type of shock determine the treatment?

Shock Also called hypoperfusion and can be called “a clinical set of signs and symptoms associated with an inadequate supply of blood to body organs, especially the brain and heart”

When shock occurs, the body attempts to increase blood flow to the brain, heart, and vital organs by reducing blood flow to other body parts and can lead to: Cyanosis Cool Skin Diaphoresis Tachycardia Tachypnea Hypotension Weakness, Confusion, or Unconsciousness Anxiety and Restlessness Excessive Thirst, N/V Blurred Vision, Sunken eyes, & Dilated Pupils

Treatment is Directed at Eliminating the Cause Improving Circulation, especially to the brain and heart Providing adequate O2 supply Maintaining Body Temp (98.6 Oral)

Anaphylactic Shock Allergic Reaction to food, meds, stings, bites, or chemicals Body releases histamines which causes vasodilation and hives (urticaria)

Cardiogenic Shock Heart Damage (MI or AMI) Heart is unable to pump and BP drops

Hemorrhagic Shock Severe Bleeding Decrease blood volume

Metabolic Shock Severe N/V, diarrhea, heat illness, or diabetes Hypotension Occurs

Neurogenic Shock Injury to the brain and/or spinal cord injury Nervous system loses the ability to control the size of blood vessels and hypotension occurs

Psychogenic Shock Emotional distress such as anger, fear, or grief Emotional response causes massive vasodilation and causes hypotension (Fight or Flight)

Respiratory Shock Choking, Trauma to the Respiratory Tract or chronic disease Interferes with the Oxygen exchange between the lungs and the blood stream

Septic Shock Acute Infection (Toxic Shock Syndrome) Poisons or toxins in the blood cause vasodilation and hypotension Usually documented along with Septicemia

TX Supine, Feet Up at least 12 inches Cover w blanket and make sure a blanket is under the patient to keep them warm, but do not overheat Precautions: * N/V, Bleeding of the mouth, Head or Neck injury,* Do not give anything PO
