Presentation on theme: "LESSON 9 SHOCK 9-1."— Presentation transcript:


2 Shock Dangerous condition
Not enough oxygen-rich blood reaching vital organs such as brain and heart Caused by anything that significantly reduces blood flow Life-threatening emergency May develop quickly or gradually Always call for victim in shock 9-2

3 Normal Tissue Oxygenation
Three general conditions must be present: Heart must efficiently pump blood Blood volume sufficient to fill blood vessels Blood vessels intact and functioning normally 9-3

4 Causes of Shock Severe bleeding Severe burns Heart failure
Heart attack Head or spinal injuries Severe allergic reactions Dehydration Electrocution Serious infections Extreme emotional reactions (temporary/less dangerous) 9-4

5 Common Types of Shock Hypovolemic occurs when blood volume drops
Cardiogenic occurs with diminished heart function Neurogenic occurs with nervous system problems Anaphylactic extreme allergic reaction 9-5

6 Development of Shock Assume any victim with serious injury is at risk for shock Often occurs in stages May progress gradually or quickly Victim ultimately becomes unresponsive Not all victims experience all signs and symptoms of shock 9-6

7 Signs and Symptoms of Shock
In compensatory shock (first stage): Anxiety, restlessness, fear Increased breathing and heart rate In decompensatory shock (second stage): Mental status continues to deteriorate Breathing becomes rapid and shallow, and heartbeat rapid Skin becomes pale or ashen and cool Nausea and thirst occur 9-7

8 Signs and Symptoms of Shock continued
In irreversible shock (third stage): Victim becomes unresponsive Respiratory and cardiac arrest 9-8

9 Urgency of Shock Treatment
Shock continues to develop unless medical treatment begins Call immediately 9-9

10 First Aid for Shock Check for responsiveness, normal breathing and severe bleeding, and care for life-threatening injuries first. Call 9-10

11 First Aid for Shock continued
Have victim lie on back and raise legs so that feet are 6-12 inches above the ground. Put breathing, unresponsive victim (if no suspected spinal injury) in recovery position Loosen any tight clothing. 9-11

12 First Aid for Shock continued
Be alert for vomiting; turn victim’s head to drain mouth. Maintain normal body temperature. 9-12

13 Shock in Children Blood loss in infants/children may quickly lead to shock Susceptible to shock from dehydration Early shock may be less obvious but child’s condition rapidly declines Treatment is same as for adults 9-13

14 Anaphylaxis Severe allergic reaction in some people
Also called anaphylactic shock Life-threatening emergency because airway may swell Always call 9-1-1 9-14

15 Causes of Anaphylaxis Common allergens: Certain drugs Certain foods
Insect stings and bites 9-15

16 Development of Anaphylaxis
Signs and symptoms may begin within seconds to minutes The more quickly it occurs – the more serious You cannot know how severe the reaction will be 9-16

17 Signs of anaphylaxis Itching Redness Swelling Progressing to:
Tightness in the chest Difficulty breathing Unconsciousness

18 Prevention of Anaphylaxis: Medication Allergies
Maintain a history of medication reactions and share it with health care providers Wear a medical alert ID Read product labels carefully 9-18

19 Prevention of Anaphylaxis: Insect Stings
Stay away from insect nesting areas Check around home for insect nests Wear clothing that covers arms and legs Wear shoes Do not swat or wave insects away 9-19

20 Emergency Epinephrine
Auto-Injector May be carried by people with severe allergies Medication stops anaphylactic reaction Ask a victim about it Help victim open and use auto-injector 9-20

21 First Aid for Anaphylaxis
Call 9-1-1 Help victim use his or her epinephrine auto-injector Monitor victim’s breathing and be ready to give CPR if needed Help victim sit up in position of easiest breathing - put unresponsive victim who is breathing in recovery position 9-21
