Hemorrhage (excessive loss of blood) Excessive Pain Infection Heart Attack Stroke Poisoning (by chemicals, drugs or gases) Lack of O2 Psychological trauma Dehydration
Allergic Reaction to food, meds, stings, bites, or chemicals Body releases histamines which causes vasodilation (blood vessels get larger) and hives (urticaria) Respiratory Distress may occur and is Life Threatening. http://www.youtube.com/watch ?v=Ftyx5gVx_d0 http://www.youtube.com/watch ?v=Ftyx5gVx_d0
Heart Muscle Damage from MI or Cardiac Arrest Heart is unable to pump and BP drops
Severe Bleeding or loss of plasma Decrease blood volume causes blood pressure to drop Decreased blood flow to body cells Decrease in blood volume
Severe N/V, diarrhea, heat illness, or diabetes Decreased amount of fluid causes dehydration and disruption in normal acid-base balance of the body. Bp drops & less blood circulates to the cells.
Injury to the brain and/or spinal cord injury Nervous system loses the ability to control the size of blood vessels and hypotension occurs http://www.youtube.com/watch?v=qcnsZ5fM lw4 http://www.youtube.com/watch?v=qcnsZ5fM lw4
Emotional distress such as anger, fear, or grief Emotional response causes massive vasodilation and causes hypotension (Fight or Flight)
Choking, Trauma to the Respiratory Tract or chronic disease Interferes with the Oxygen exchange between the lungs and the blood stream
Acute Infection (Toxic Shock Syndrome) Poisons or toxins in the blood cause vasodilation and hypotension Usually documented along with Septicemia
The position for treating shock is based on the victims injuries. Head Injury: Apply pressure on the injury and keep the victim laying flat. Do Not elevate head or lower extremities. Chest Injury: Raise the head and shoulder slightly Nausea/Vomiting or Unconsciousness: Keep the victim lying on one side (known as recovery, coma or lateral position) preferably opposite from his injury except for sucking wound and stroke.
