- Slide 1
- RESPONDING TO SHOCK Brooke and Annmarie Period 4
- Slide 2
- What is Shock? A life-threatening condition occurs when the circulatory system fails to provide adequate oxygenated blood to all parts of the body
- Slide 3
- How Shock Occurs An adequate amount of blood must be circulating in the body when this doesnt happen, shock occurs. This shuts down all non-essential organs: the brain, heart and lungs. Blood volume: the total amount of blood circulating within the body
- Slide 4
- Domino Effect Injury causes severe bleeding Heart attempts to compensate for the disruption of blood flow by beating faster As blood volume drops, pulse weakens Blood vessels constrict in the arms, legs and skin, making the skin appear pale or ashen and feels cool Due to stress, body perspires heavily and skin feels moist
- Slide 5
- Domino Effect (cont.) Cells start to die in the arms and legs Brain then sends signal to return blood to arms and legs Vital organs dont receive enough blood Heart tries to compensate by beating faster, more blood loss Vital organs fail to function properly Death.
- Slide 6
- Types of shock Cardiogenic shock Distributive shock Hypovolemic shock Obstructive shock
- Slide 7
- Cardiogenic Shock Failure of the heart to pump enough oxygenated blood Can be too fast or too slow (ventricular tachycardia or ventricular fibrillation) Weak and ineffective contractions can be caused by damage from disease, trauma, poisoning, or respiratory problems
- Slide 8
- Distributive Shock Abnormal dilation of the blood vessels Can be caused by spinal cord, brain trauma, infection, or anaphylaxis
- Slide 9
- Hypovolemic Shock Severe bleeding or loss of fluid from the body Inefficient blood shock
- Slide 10
- Obstructive shock Caused by an obstruction of blood flow
- Slide 11
- Other Reasons Injury to the chest Insufficient oxygen enters the bloodstream
- Slide 12
- Signals Usually caused by severe bleeding Apprehension, anxiety, restlessness or irritability Altered level of consciousness Nausea/vomiting Pale, ashen or grayish, cool, moist skin Rapid breathing Excessive thirst
- Slide 13
- How to Care Check and call first Open and clear the airway Control external bleeding Immobilize injuries Lie down the victim in a comfortable position Elevate feet to direct blood to essential organs Keep at normal body temperature, use a blanket or shading device if necessary Do not give food or water (even if the victim shows excessive thirst) Calm and reassure the victim Monitor breathing and watch for changes in condition

- Summary 1. Shock is a life-threating condition that must be cared for immediately. 2. If not cared for immediately, the body will shut due to the Domino Effect. 3. To recognize shock, first look for severe bleeding (most common signal) and see if the person is conscious. Then check the skin to see if it is turning ashen, pale or moist. 4. Once you have checked and called, care by opening the airway, controlling external bleeding, immobilizing injuries, and laying the victim on his/her back in a comfortable position. If you can, elevate the legs, cover with a blanket/shading device, and calm/reassure. Remember to monitor breathing and not allow the victim to eat/drink.

- Scenario You are at Medieval Times with some friends watching a jousting tournament. Suddenly, you notice that one of the knights is accidently been impaled by his opponents lance in the stomach area. He is on his back on the floor and has already lost a lot of blood. The staff clears the area of the horses and any sharp objects. When you check the man and he is fading in and out of consciousness. His skin is turning pale and ashen, and it seems very moist. His breathing is rapid and he seems to show signs of nausea. What do you do next?
