Lesson 14: Cardiac Emergencies

Introduction • Cardiovascular disease is the leading cause of death for men and women in the United States • Coronary heart disease is the most common type of cardiovascular disease • Two common cardiac emergencies are heart attack (also known as myocardial infarction) & cardiac arrest • A heart attack refers to a condition in which the blood flow to the heart muscle is compromised and the heart begins to die • The term cardiac arrest refers to a condition in which the heart stops beating

Cardiac Chain of Survival Cardiopulmonary resuscitation (CPR) is a combination of chest compressions and rescue breaths

• Cardiac Chain of Survival:

 Early recognition and early access  Early CPR AMERICAN CROSS defibrillation  RED Early FIRST AID–RESPONDING  Early advanced medical care TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

•

Cardiac Chain of Survival CPR artificially takes over the

functions of the lungs & heart • Only about 1/3 of the normal blood flow to the brain. Therefore, CPR alone is not enough

Recognizing Signals of a Heart Attack • Heart attacks are caused by an obstruction in the coronary arteries • This blockage leads to death of the heart muscle • Pain is described as:       

Uncomfortable pressure Squeezing Crushing Tightness Aching Constricting Heavy sensation in the chest AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by The American National Red Cross All rights reserved.

Recognizing Signals of a Heart Attack (continued)

• Any severe chest pain, pain lasting longer than 3 to 5 minutes or chest pain accompanied by other signals of a heart attack should receive emergency medical care immediately • Other signals include:  Trouble breathing  Paleness  Ashen skin or bluish skin, particularly around the face  Skin may also be moist

Care for a Heart Attack • • • •

Follow CHECK—CALL—CARE Call 9-1-1 or the local emergency number Have the victim stop all physical activity Loosen any restrictive clothing and have the victim rest • Monitor the victim closely • Be prepared to perform CPR or use an AED • Talk to bystanders to find out what happened • Assist the victim to take prescribed medication • Do not try to drive the victim to the hospital yourself • Aspirin may be given under certain circumstances, after 9-1-1 has been called AMERICAN RED CROSS • Demonstrate a calm, reassuring manner FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Angina Pectoris • Angina pectoris develops when the heart needs more oxygen than it gets • When the coronary arteries are narrow & the heart needs more oxygen, heart muscle tissues may not get enough oxygen • Pain associated with angina seldom lasts longer than 3 to 5 minutes • Nitroglycerin temporarily widens the arteries & therefore helps relieve the pain • If there is no relief after 10 minutes, call for help

AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Cardiac Arrest • Cardiac arrest occurs when the heart stops beating or beats too ineffectively to generate a pulse and blood cannot be circulated to the brain and other vital organs • A victim in cardiac arrest is unconscious and shows no signs of life • Causes: – Cardiovascular disease – Drowning – Suffocation – Certain drugs Severe AMERICAN–RED CROSS blood loss FIRST AID–RESPONDING – Electrocution TO EMERGENCIES FOURTH EDITION – Stroke Copyright © 2005, – Other types of brain damage revised edition 2007, by

Cardiac Arrest (continued)

• Signs of life include:  Normal breathing  Movement  A pulse (for children & infants)

• The victim’s skin may be pale, ashen or bluish, particularly around the face. The face may also be moist from perspiration • In some cases, a victim of cardiac arrest may not have shown any warning signals. This condition is called sudden death AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Lesson 15: CPR & Unconscious Choking: Adult/Child/Infant

Introduction • An adult victim who is in cardiac arrest is unconscious and shows no signs of life. • CPR can help circulate blood containing oxygen by a combination of chest compressions (1.5 to 2 in) and rescue breaths. • When you perform CPR, give cycles of 30 compressions and 2 rescue breaths for an adult. AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Unconscious Choking: Adult • The care for an unconscious choking adult is very similar to the skill of adult CPR, except that you look for a foreign object in the victim’s mouth between compressions & breaths • Chest compressions are used to help force air from the victim’s lungs to dislodge a foreign object AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Child Introduction • Children seldom initially suffer a cardiac emergency. Instead, they suffer a respiratory emergency that results in a cardiac emergency • Use the emergency action steps: CHECK—CALL— CARE to determine if you need to perform CPR • A child is in cardiac arrest if he or she is unconscious, shows no signs of life (movement or breathing) including no pulse • CPR can help circulate blood containing oxygen through a combination of chest compressions and rescue breaths • When you perform CPR, give cycles of 30 compressions and 2 rescue breaths for a child. AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Unconscious Choking: Child • The care for an unconscious choking child is very similar to the skill of child CPR except that you look for a foreign object in the child’s mouth between compressions and breaths • Chest compressions (1-1 ½ ) are used to help force air from the child’s lungs to dislodge the object AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Introduction • Unlike adults, infants seldom initially suffer a cardiac emergency. Instead, they suffer a respiratory emergency that results in a cardiac emergency • An infant is in cardiac arrest if he or she is unconscious, shows not signs of life (movement and breathing) including no pulse in an infant • CPR can help circulate blood containing oxygen through a combination of chest compressions (1/2 -1in) & rescue breaths • When you perform CPR, give cycles of 30 compressions and 2 breaths for an infant

AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Unconscious Choking:Infant • If you attempt rescue breaths but are unable to make the chest clearly rise, you must act quickly to get air into the infant. • Care for an unconscious choking infant is very similar to the skill of infant CPR, with the exception that you look for a foreign object in the mouth between compressions and breaths • Chest compressions are used to help force air from the infant’s lungs to dislodge the object

Lesson 18: Adult AED (Automated External Defibrillation)

Introduction

AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Introduction (continued)

• Most victims of sudden cardiac arrest need an electric shock, called defibrillation • Each minute that defibrillation is delayed reduces the victim’s chances of survival by about 10% • The sooner the shock is administered, the greater the likelihood of the victim’s survival AMERICAN RED CROSS FIRST AID–RESPONDING TO EMERGENCIES FOURTH EDITION Copyright © 2005, revised edition 2007, by

Automated External Defibrillation • Disease or injury can disrupt the heart’s electrical system and damage the heart • An automated external defibrillator (AED) is a machine that analyzes the heart’s rhythm and, if necessary, tells you to deliver a shock to a victim of a sudden cardiac arrest • Defibrillation is an electric shock that interrupts the heart’s chaotic electrical activity during sudden cardiac arrest, which is most commonly caused by an abnormal rhythms such as ventricular fibrillation. The shock may help restore the heart’s ability to function as a pump
