CPR/AED Course

Chapter 2 Why CPR?

Cardiopulmonary resuscitation (CPR) is crucial because it can save lives in emergency situations where a person’s heart has stopped beating (cardiac arrest) or they have stopped breathing. Here are the key reasons why CPR is important:

1. Maintains Blood Flow: CPR helps to manually circulate blood to the brain and vital organs, providing oxygen and delaying tissue death until professional medical help can arrive.
2. Increases Survival Chances: Immediate CPR can double or even triple the chances of survival after cardiac arrest, particularly if performed within the first few minutes.
3. Buys Time: CPR keeps the blood flowing, which buys time for emergency responders to arrive and provide advanced care, such as defibrillation or medications.
4. Prevents Brain Damage: By ensuring that oxygen-rich blood reaches the brain, CPR helps prevent brain damage, which can occur just minutes after the heart stops beating.
5. Empowers Bystanders: Knowing CPR empowers bystanders to take action in an emergency, potentially saving the lives of friends, family, or strangers.

In summary, CPR is a critical life-saving technique that can make a significant difference in emergency situations, often determining the outcome for the victim.

Chapter 3 The CPR Survival Chain

The CPR Survival Chain is a vital sequence of steps essential in maximizing the chances of survival during cardiac emergencies. Each link in this chain plays a crucial role in improving outcomes for the victim. Understanding and executing each step effectively could significantly increase the likelihood of saving a life.

1. Early Access:
   • Identifying the signs of cardiac arrest promptly is the first link in the chain. This involves recognizing if the individual is unresponsive and not breathing normally.
   • Activating EMS by calling for help as soon as cardiac arrest is identified ensures professional medical assistance arrives swiftly. This step initiates the response process.
2. Early CPR:
   • Beginning CPR (Cardiopulmonary Resuscitation) immediately after recognizing cardiac arrest is crucial. Compressions and rescue breaths help maintain blood circulation and oxygenation until professional help arrives.
3. Early Defibrillation:
   • The use of an Automated External Defibrillator (AED) in the early stages of cardiac arrest is proven to be highly effective. It delivers an electrical shock to restore the heart’s rhythm, potentially increasing the chances of survival.
4. Early Advance Care:
   • After the arrival of emergency medical personnel, advanced life support measures are initiated. This involves advanced airway management, medication administration, and continuous monitoring. Post-resuscitation care also plays a critical role in long-term recovery.

Each link in this chain is pivotal, and the effectiveness of the entire process relies on the seamless execution of these steps. Understanding and practicing the CPR Survival Chain ensures a coordinated and efficient response in the event of a cardiac emergency, improving the likelihood of a positive outcome for the victim.

Chapter 4 Compressions-Airway-Breathing (C-A-B)

In the event of a cardiac emergency, knowing the sequence of actions for effective Cardiopulmonary Resuscitation (CPR) is crucial. The C-A-B approach is a fundamental principle that guides the steps required to resuscitate an unresponsive individual.

This chapter focuses on the sequence of actions to perform CPR effectively:

1. Compressions (C):

   Understanding the significance of chest compressions in CPR. We’ll cover the correct hand placement, depth, and rate of compressions necessary to circulate oxygenated blood throughout the body.

2. Airway (A):

   Establishing and maintaining an open airway is essential to ensure effective breathing. The upcoming chapter will discuss the methods to clear the victim’s airway obstruction and position the head correctly for optimal air exchange.

3. Breathing (B):

   Administering rescue breaths properly can provide essential oxygen to the victim’s lungs and bloodstream. We’ll explain the technique for delivering rescue breaths, the correct ratio of breaths to compressions, and considerations for rescue breathing in different situations.

This chapter aims to provide comprehensive guidance on the C-A-B sequence, enabling you to perform critical CPR techniques confidently and effectively. Understanding the correct sequence and techniques is vital for maximizing the chances of survival during cardiac emergencies.

Chapter 5 Assessment for CPR

Before initiating Cardiopulmonary Resuscitation (CPR), a thorough assessment of the victim’s condition is essential. This chapter focuses on the critical steps involved in assessing an individual in need of CPR:

1. Scene Safety:

   Safety is paramount. Learn how to assess the scene for potential dangers or hazards before approaching the victim. Ensure the environment is safe for both you and the victim before proceeding. In addition, gather any available personal protective gear before approaching the victim.

2. Victim Responsiveness:

   Determine if the victim is conscious and responsive. Learn various methods to check for responsiveness, including calling out, tapping the victim, and assessing for any response or movement. Use verbal cues like “Are you okay?” and physical prompts to check for responsiveness. If the victim is unresponsive, proceed with the following steps.

   

   
   
3. Activate Emergency Medical Services (EMS):

   If the victim is unresponsive or unconscious, instruct someone to call emergency services (such as 911 or local emergency number). If alone, activate EMS yourself before beginning CPR.

   

   
   
4. Check for Normal Breathing:

   Assess the victim’s breathing pattern. Learn how to look, listen, and feel for any signs of normal breathing within 10 seconds. Recognize that infrequent gasps or agonal respirations do not signify normal breathing.

   

   
   
5. Assess for Severe Bleeding or Other Obvious Injuries:

   While performing the primary assessment, check for severe bleeding or obvious injuries that may require immediate attention before starting CPR.

   

   
   

Understanding these critical assessment steps is vital for determining the need for CPR and initiating life-saving interventions promptly. This chapter provides detailed guidance on performing a quick and efficient assessment, enabling you to make informed decisions and take necessary actions during emergencies requiring CPR.

Chapter 6 Adult Compressions

*Note: An adult in the context of CPR emergencies refers to individuals who have undergone or completed puberty.*

Steps for Administering Chest Compressions to an Adult:

*Position yourself beside the victim.

*Ensure the victim is lying on their back on a stable, level surface.

*If the victim is unconscious and face down, turn them face up while supporting the head, neck, and back.

*Promptly remove any clothing obstructing the chest area.

Adopt the appropriate hand placement for chest compressions:

– Position the heel of your hand on the breastbone, situated between the nipples.

– Place the other hand on top of the first hand, interlocking the fingers.

– Keep the fingers clear of the chest.

Assume the correct body posture for CPR: kneel down, maintain straight arms positioned over the chest, and align your shoulders above your hands. Ensure your elbows are locked.

Administer 30 forceful and rapid compressions, pushing at least 2 inches (5 cm) but no more than 2.4 inches deep, maintaining a rate of at least 100 to 120 compressions per minute.

Chest Recoil: Ensure the chest rises fully after each compression. Do not lean on the victim’s chest after each compression cycle.

*Remember 30 Compressions*

HANDS ONLY CPR Cycle:

Hands-only CPR is an essential life-saving technique that can be performed by bystanders when someone suddenly collapses and is unresponsive, particularly in cases of sudden cardiac arrest. This method focuses on delivering high-quality chest compressions without rescue breaths, making it easier for untrained individuals to provide immediate assistance. To perform hands-only CPR, place the heel of one hand on the center of the victim’s chest, place the other hand on top, and interlock your fingers. Hands-only CPR is crucial in the first few minutes following cardiac arrest, as it maintains blood flow to vital organs until professional medical help arrives, significantly increasing the victim’s chances of survival.

WHO’S IT FOR? Any adult who collapses, stops breathing, and is unresponsive. Mouth-to-mouth breaths are still necessary for children, infants, and drowning victims.

WHAT TO DO: First, call 911 or ask a bystander to do so. Then, press hard and fast, approximately 100-120 times per minute, at the lower portion of the victim’s chest. Continue until EMS arrives, an AED becomes available, or you are too tired to continue.

Two-Rescuer Technique – Utilized when a second rescuer is available for assistance:

Allow the second rescuer to activate the Emergency Response System (dial 9-1-1) and retrieve the AED.

The first rescuer should remain with the victim, be prepared to remove clothing from the chest, and initiate CPR.

When both rescuers are present with the victim, they should alternate performing 30 chest compressions, switching approximately every 2 minutes. Rescuers should remind each other to push down at least 2 inches but no more than 2.4 inches deep and monitor for proper chest recoil.

Chapter 7 Adult CPR: Airway And Breaths

Following every set of 30 compressions, proceed to open the airway and provide two rescue breaths, a breath a second. Your ability to administer breaths will further assist the victim.

Before administering breaths, it’s crucial to clear the airway and confirm there are no blockages, with the tongue being a common obstruction. If there’s a visible foreign object that can be easily removed, take it out.

Engage in the head-tilt chin-lift maneuver or a jaw thrust maneuver.

Opening of the Airway:

Performing a Head Tilt-Chin Lift:

Adhere to these steps for executing a head tilt-chin lift:

• Position one hand on the victim’s forehead, using your palm to gently tilt the head backward.

• Place the fingers of your other hand under the bony section of the lower jaw, near the chin.

  • Elevate the jaw to bring the chin forward. While conducting a head tilt-chin lift, ensure to:
  • Refrain from exerting excessive pressure under the chin, as this might obstruct the airway.
  • Avoid completely closing the victim’s mouth.

Tilt the head back while pinching the nose with one hand. Simultaneously, use the other hand to lift the chin, effectively opening the airway.

Jaw Thrust Maneuver:

When the head tilt-chin lift is ineffective or, in cases of suspected spinal injury, resort to the jaw thrust technique.

Follow these steps to execute a jaw thrust:

• Position yourself at the victim’s head.
• Place one hand on either side of the victim’s head, possibly resting your elbows on the surface supporting the victim.
• With fingers positioned beneath the angle of the victim’s lower jaw, employ both hands to lift and push the jaw forward.
• In case the victim’s lips close, utilize your thumbs to separate the lower lip, ensuring the lips remain parted.
• If the jaw thrust fails to open the airway, resort to a head tilt-chin lift.

Breaths:

Ensure the airway is open, pinch the nose, and deliver air into the victim’s mouth. Seal your mouth firmly over theirs; use a protective barrier if accessible. Administer 2 breaths, each lasting for one (1) second each. Confirm that the chest rises and falls between each breath.

Methods to Administer Rescue Breaths for CPR:

1. Mouth-to-Mouth Technique:

• Ensure the airway is clear of any obstructions.
• Tilt the head back slightly to open the airway.
• Pinch the victim’s nose shut.
• Take a normal breath, make a complete seal over the victim’s mouth, and deliver a breath that lasts about one second.
• Watch for the chest to rise and fall.

4. Barrier Devices:

• Use a CPR face mask or shield to prevent direct contact.
• Position the mask over the victim’s mouth and nose, ensuring a secure seal.
• Deliver breaths through the one-way valve.

If the breaths you provide do not enter, continue performing chest compressions following the 30:2 ratio until the breaths are effective. Avoid pausing compressions for more than 10 seconds.

Continue the cycle of 30 chest compressions and 2 rescue breaths, maintaining a rate of at least 100 to 120 compressions per minute until the arrival of an AED, EMS, and/or the victim exhibits signs of breathing (signs of life).

If the individual starts breathing, gently roll them onto their left side into a Recovery Position while awaiting EMS. In the recovery position, any vomit or fluids will naturally drain from the mouth. When moving the victim, take special care to support the neck, head, and back.

Note: Hands-only CPR is a critical, life-saving technique ideal for situations when a bystander does not feel comfortable performing mouth-to-mouth resuscitation or lacks a face shield or pocket mask.

Chapter 8 Adult CPR: Putting It All Together

Having familiarized yourself with the specifics of adhering to the C-A-B method and executing Compressions, Opening the Airway, and Providing Breaths, let’s combine the Adult CPR technique!

Ensure the safety of the environment and don personal protective equipment (PPE) if available.

Gently tap on shoulders and loudly ask, “Are you okay?” to assess the victim’s responsiveness.

Call for assistance if available.

Activate Emergency Medical Services (EMS) and retrieve the AED.

Check for signs of breathing by looking, listening, and feeling for at least 5 seconds no more than 10 seconds.

Administer 30 chest compressions, maintaining a depth of 2 inches (5cm).

Open the airway using the head-tilt chin-lift technique or jaw thrust technique.

Provide 2 breaths, each lasting 1 second each.

Continue the cycle of 30 compressions and 2 rescue breaths until help arrives, aiming for a rate of 100 to 120 compressions per minute.

Don’t forget to reassess the victim after 2 minutes for breathing.

Chapter 9 AED

An Automated External Defibrillator (AED) delivers an electric shock to the heart, restoring the heart to a regular rhythm. This device guides you through the process step-by-step and prompts you to press a button if it identifies the need for a shock. AEDs are user-friendly devices, enabling both laypersons and healthcare providers to safely attempt defibrillation.

A diagram will indicate pad placement and when to resume compressions. If a second rescuer is present, they can assist in attaching AED pads while the first rescuer continues CPR.

The timely use of an AED significantly increases the survival rate of a victim experiencing a cardiac emergency to approximately 30-70 percent.

Avoid contact with the individual while the AED is analyzing, as there’s a risk of being shocked during the defibrillation process. Be cautious.

Do not utilize an AED on someone in contact with water; move them away from any water source and wipe off their chest before defibrillating.

An AED can be utilized on a victim with an implanted device.

Before defibrillation, remove visible medication patches from the victim while wearing disposable gloves.

Ensure the shock pads are placed on clean, dry skin; shave if necessary, and make certain the chest is dry.

1. Assess the Situation:
   • Ensure the safety of the surroundings.
   • Check the responsiveness of the victim and activate emergency services (call 911 or your local emergency number).
2. Turn on the AED:

   Locate and turn on the AED. Most AEDs have a power button that is easily visible.

3. Follow Voice or Screen Prompts:
   • AEDs are designed to provide step-by-step instructions through voice prompts or a screen display.
   • Listen carefully to the voice prompts or follow the visual instructions.
4. Attach Electrode Pads:
   • Attach the electrode pads to the victim’s bare chest as shown in the diagram on the pads.
   • Place one pad on the upper right chest, just below the collarbone.
   • Place the other pad on the lower left side of the chest, just below the armpit.
5. Ensure Clear Chest:

   Ensure that the chest is dry and clear of any medication patches, excessive chest hair, or other obstructions.

6. Analyze Heart Rhythm:

   Let the AED analyze the victim’s heart rhythm. Ensure that no one is touching the victim during this analysis.

7. Follow Prompts for Shock or CPR:
   • If the AED advises a shock, make sure everyone is clear, and then press the shock button.
   • If no shock is advised, follow the AED’s prompts for initiating CPR.
8. Perform CPR as Instructed:

   If CPR is advised, follow the AED’s instructions for chest compressions and rescue breaths until emergency medical personnel arrive.

9. Continue as Directed:

   Continue following the AED’s prompts until emergency services take over, the victim starts breathing on their own, or you are too exhausted to continue. After initiating CPR and following AED prompts, it’s important to reassess the victim’s condition every 2 minutes for breathing.

Never power off the AED or remove the pads. The machine will prompt you to start CPR after delivering the shock.

For child/infant AED usage: The device will guide you to use child pads or a specific child key/switch. If child pads aren’t available, use adult pads. If using child pads, place one pad on the front of the chest and another on the back.

(Using an AED on a Child)

(Using an AED on an Infant)

Please note: Begin CPR immediately, if the AED is unavailable!

Chapter 10 Child CPR

Typically, a child’s cardiac arrest is often due to a breathing-related issue. Hence, the integration of breaths with compressions holds significant importance for children. When addressing a child during a CPR emergency, adhere to the same procedures for compressions, airway, and breathing as outlined for adults. However, below are the

SPECIFIC GUIDELINES for CHILD CPR:

Witnessing a Collapse:

For witnessed collapse incidents, proceed with the steps intended for adults and adolescents in CPR.

Unwitnessed Collapse:

In cases of unwitnessed collapse, perform CPR for 2 minutes initially. Then, temporarily leave the victim to activate the emergency response system and acquire the AED.

Return promptly to the child or infant and resume CPR, utilizing the AED as soon as it becomes accessible.

Child CPR involves specific techniques tailored for infants and children. Here is a guide on how to administer CPR to a child:

1. Assess the Situation:
   • Check the surroundings for safety.
   • Tap the child and shout loudly to assess responsiveness.
2. Activate Emergency Response:

   If the child is unresponsive, immediately call 911 or your local emergency number.

3. Open the Airway/Breathing:
   • Place the child on their back on a firm surface.
   • Tilt the head back slightly to open the airway.
   • Look, listen, and feel for signs of breathing for no more than 10 seconds.
   • If the child is not breathing or only gasping, begin CPR.
4. Chest Compressions:

   Compression to breath ratio: 30:2

   • For a child (1 to 8 years old), use one or two hands for chest compressions.
   • Allow the chest to fully recoil between compressions.
   • Position the heel of one hand at the chest’s center, placed between the nipples. Using the second hand might not be necessary unless required to ensure proper compression.
   • Administer forceful and rapid compressions of approximately 2 inches (5 cm) deep, maintaining a rate of at least 100 to 120 compressions per minute.

   The methods for managing the airway and providing breaths are identical to those used for adults. Please Note: One-hand compression is optional.

   

5. Rescue Breaths:
   • Provide 2 rescue breaths after 30 compressions.
   • Use the mouth-to-mouth or mouth-to-nose technique for two breaths.
   • Each breath should last about one second and make the chest rise.
6. Continue CPR:
   • Continue the cycle of 30 compressions and 2 rescue breaths.
   • Continue until the child starts breathing on their own, emergency medical personnel arrive, or you are too exhausted to continue.
7. Use an AED (if available):

   If an automated external defibrillator (AED) is available, follow the device’s prompts for use.

Chapter 11 Infant CPR

Typically, an infant’s cardiac arrest occurs due to a breathing-related issue. Hence, the combination of breaths with compressions holds great significance for infants. the procedure for addressing an infant mirrors that for responding to a child, with the Infant CPR involves specific techniques tailored for babies under the age of one.

Here’s a step-by-step guide on how to administer CPR to an infant:

Infant: Younger than 1 year.

1. Assess the Situation:
   • Ensure the safety of the surroundings.
   • Tap the infant’s foot and shout loudly to assess responsiveness.
   • Place the infant on a firm surface, such as a table or the ground.
2. Activate Emergency Response:

   If the infant is unresponsive, immediately call 911 or your local emergency number.

3. Open the Airway/Breathing:
   • Place the infant on their back on a firm surface.
   • Tilt the head back slightly to open the airway.
   • Look, listen, and feel for signs of breathing for no more than 10 seconds.
   • If the infant is not breathing or only gasping, begin CPR.
4. Chest Compressions:

   Compression to breath ratio: 30:2

   • Use two fingers to compress the infant’s chest just below the nipple line.
   • Compress the chest at least 1.5 inches (4 cm) deep at a rate of about 100-120 compressions per minute.
   • Allow the chest to fully recoil between compressions.

   

5. Rescue Breaths:
   • Provide 2 gentle rescue breaths after 30 compressions.
   • Airway: While tilting an infant’s head to open the airway, take care not to push the head too far backward, as this might obstruct the infant’s air passage.
   • To provide rescue breaths to an infant, either cover the infant’s nose and mouth with your mouth, or pinch the infant’s nose shut using your thumb and index finger to prevent air from escaping. Ensure a tight seal over the infant’s mouth, preventing any air from escaping during the process.

   

6. Continue CPR:
   • Continue the cycle of 30 compressions and 2 rescue breaths.
   • Continue until the infant starts breathing on their own, emergency medical personnel arrive, or you are too exhausted to continue.
7. Use an AED (if available):

   If an automated external defibrillator (AED) is available, follow the device’s prompts for use.

Chapter 13 Choking: Adult /Child

Choking occurs when an object becomes lodged in the throat or windpipe, blocking the flow of air. Welcome to a comprehensive guide on responding to choking incidents in both adults and children. Choking is a serious emergency that demands immediate attention and the right set of skills. This chapter aims to equip you with the knowledge and techniques necessary to recognize and effectively respond to choking emergencies in individuals of different age groups.

Understanding Choking:

Common Causes:

• Food
• Inadequate Chewing
• Dentures
• Medical Conditions
• Foreign Objects
• Respiratory Issues

Signs and Symptoms:

– Difficulty breathing, inability to speak, and cyanosis are the most common signs of choking.

Assess the Situation:

– Ensure your safety and the safety of the adult/child.

– Ask the adult/ child if they are choking and if they need help.

If an adult or child is choking, they might indicate it using the universal choking sign, demonstrated by holding the neck with one or both hands.

Encourage Coughing:

– If the adult or child is conscious and able to cough, encourage them to cough forcefully to try and dislodge the object.

In case of choking, inquire, “Are you choking?” If the individual nods or can’t breathe or respond, inform them that you are CPR-trained and ready to assist. Position yourself behind the victim, by standing or kneeling.

Create a fist with one hand and place it on the abdomen, just above the belly button.

Clasp your fist with the other hand a couple inches above their naval and administer quick, upward abdominal thrusts.

Continue these thrusts until the obstruction is cleared, enabling the victim to breathe or cough vigorously, OR until the victim becomes unconscious and call for help and activate emergency response system.

For pregnant women or individuals larger than you, perform chest thrusts instead of abdominal thrusts.

If the adult or child becomes unconscious and activates the emergency response system, proceed with the steps for administering adult/child CPR. Before initiating rescue breaths (30:2 compression-to-breath ratio), check inside the mouth. If you see an object, use your finger to scoop it out. If the object is not visible, proceed with rescue breaths. Never perform a blind finger sweep to avoid causing further harm.

Chapter 14 Choking: Infant

In the event of a conscious choking infant unable to cough, cry, or breathe, you should proceed with 5 back blows and 5 chest thrusts by following these guidelines:

Place the infant face-up on your forearm with their head positioned lower than your chest. Ensure proper support for the head and neck by firmly holding it in your palm. Transition the infant face-down while maintaining support with your forearm on your thigh.

Administer 5 back blows between the infant’s shoulder blades using the heel of your hand.

If the object remains lodged after the back blows, revert the infant to a face-up position and deliver 5 chest thrusts.

For chest thrusts, press down with two to three fingers at the center of the infant’s chest, akin to the technique used in infant CPR.

Continue alternating between back blows and chest thrusts until the object is expelled, the infant starts responding, or the infant loses consciousness.

In the case of an unconscious infant, proceed with the steps for performing infant CPR. Before initiating rescue breaths (30:2 compression-to-breath ratio), check inside the mouth. If you see an object, use your finger to scoop it out. If the object is not visible, proceed with rescue breaths. Never perform a blind finger sweep to avoid causing further harm.

Chapter 15 Good Samaritan Law

The Good Samaritan law is a legal principle designed to protect individuals who voluntarily provide assistance to those who are injured or in danger. The law varies by jurisdiction but generally offers legal protection to bystanders who render aid in emergency situations, shielding them from liability for any unintentional harm that may occur while attempting to help. The purpose of the Good Samaritan law is to encourage people to intervene and provide assistance in emergencies without fear of facing legal repercussions, thus promoting public safety and well-being.

Chapter 16 Conclusion

In conclusion, the combined knowledge and application of CPR, AED use, and choking response are vital components of emergency first aid that can save lives in critical situations. CPR, whether hands-only or including rescue breaths, helps maintain blood flow to vital organs during cardiac arrest, while an AED can provide a necessary shock to restart the heart’s normal rhythm. In cases of choking, quick and effective intervention using the Heimlich maneuver can dislodge an obstruction and restore normal breathing. Immediate action from bystanders in these emergencies is crucial, as it can significantly improve survival rates and outcomes. Training more people in these life-saving techniques and ensuring easy access to AEDs in public spaces are essential steps toward enhancing community preparedness. With the right knowledge and tools, bystanders can make a profound difference, offering critical support and potentially saving lives in moments of medical crisis.
