Cardiopulmonary Resuscitation (CPR) is a critical life-saving technique used in emergencies where a person’s heartbeat or breathing has stopped. CPR compressions, performed at a correct rate of 100 to 120 compressions per minute, play a crucial role in maintaining vital blood flow to the brain and heart, buying precious time until professional medical help arrives. Knowing when to administer CPR and understanding the specific scenarios that require it is essential for providing immediate care and significantly increasing the chances of survival for the affected person. Millions of individuals are trained each year in CPR and other life-saving techniques.
Introduction
Cardiopulmonary resuscitation (CPR) is a lifesaving technique that involves chest compressions and rescue breaths to maintain blood circulation and oxygenation of the brain during cardiac arrest. CPR is an essential skill for first aid responders, and its proper execution can significantly improve the chances of survival for individuals who experience sudden cardiac arrest. Understanding when and how to perform CPR can make a critical difference in emergency situations.
What is Cardiopulmonary Resuscitation (CPR)?
Cardiopulmonary resuscitation (CPR) is a medical intervention that combines chest compressions and rescue breaths to restore blood circulation and oxygenation of the brain during cardiac arrest. When the heart stops beating, immediate action is crucial to maintain blood flow and oxygen supply to vital organs. CPR is typically performed by trained individuals, including medical professionals, first responders, and bystanders who have received CPR training. The goal is to keep the blood flowing until emergency medical services arrive and can provide advanced care.
Chain of Survival
The Chain of Survival is a concept that outlines the critical steps necessary to save a life during cardiac arrest. The Chain of Survival consists of five links:
-
Recognition of Cardiac Arrest and Activation of the Emergency Response System: Quickly identifying cardiac arrest and calling emergency services is the first crucial step.
-
Early CPR with Chest Compressions and Rescue Breaths: Immediate CPR helps maintain blood flow to the brain and heart.
-
Rapid Defibrillation Using an Automated External Defibrillator (AED): Using an AED as soon as possible can restore a normal heart rhythm.
-
Effective Advanced Life Support and Post-Cardiac Arrest Care: Professional medical care, including advanced life support, is essential for recovery.
-
Integrated Post-Cardiac Arrest Care: This includes targeted temperature management and coronary reperfusion to improve outcomes after cardiac arrest.
Each link in the Chain of Survival is vital for increasing the chances of survival and recovery.
Common Scenarios Requiring CPR
CPR is most commonly required in situations where the heart or breathing has suddenly stopped. Below are some of the most typical scenarios where CPR may be necessary, with detailed explanations of each situation. Rescue breathing is a critical component of CPR when a victim shows signs of insufficient or absent breathing.
Various CPR courses are available that can be completed online or through blended learning methods.
1. Sudden Cardiac Arrest
Definition: Sudden cardiac arrest occurs when the heart suddenly and unexpectedly stops beating due to an electrical malfunction. This malfunction, often caused by conditions like ventricular fibrillation, disrupts the heart’s ability to pump blood to the brain, lungs, and other vital organs. The result is a sudden loss of consciousness and cessation of breathing.
Indicators:
-
Sudden Loss of Responsiveness: The person suddenly collapses and does not respond to shouting, tapping, or any external stimuli. They may have been active or speaking moments before the collapse.
-
Absence of Normal Breathing or Only Gasping: The person is not breathing, or is only gasping for air—a condition known as agonal breathing, which is ineffective for sustaining life.
Immediate Action: CPR should be initiated immediately upon recognizing these signs. The primary goal of CPR in this context is to manually pump the heart by compressing the chest, thereby keeping blood circulating to vital organs. If the person is not breathing, mouth-to-mouth ventilations should be performed, ensuring a proper seal and observing chest rise for effectiveness. An Automated External Defibrillator (AED) should be used as soon as it is available. The AED can deliver a shock to the heart, which is critical in restoring a normal rhythm in cases of cardiac arrest caused by ventricular fibrillation or other arrhythmias. CPR and AED training can significantly increase the chances of survival and save lives.
2. Drowning or Near-Drowning Incidents
Definition: Drowning occurs when a person’s airway is submerged in water, leading to a lack of oxygen. Near-drowning refers to situations where the person is rescued before they die but may still suffer from significant oxygen deprivation and related complications.
Indicators:
-
Unresponsive or Semi-Conscious: The person may be floating face-down in the water or lying motionless on the ground after being pulled out. They may have a weak or absent pulse.
-
Difficulty or Absence of Breathing: The person may be gasping for air, struggling to breathe, or not breathing at all. The skin may appear bluish (cyanosis) due to a lack of oxygen.
Immediate Action: Begin CPR immediately if the person remains unresponsive and is not breathing normally. In drowning cases, starting with rescue breaths is crucial because the primary issue is often a lack of oxygen rather than a sudden cardiac event. After providing two initial rescue breaths to oxygenate the lungs, proceed with chest compressions to circulate the oxygenated blood. When performing mouth to mouth breathing, it is important to follow specific steps to ensure effective rescue breathing. Continue CPR until professional medical help arrives. If the person begins breathing on their own, place them in the recovery position and monitor their breathing closely.
It is important to complete training courses on emergency response, such as anaphylaxis care and severe bleeding management, to effectively handle drowning incidents.
3. Choking Incidents
Definition:
Choking occurs when an object becomes lodged in the throat, obstructing the airway and preventing normal breathing. This obstruction can quickly lead to a life-threatening situation if not resolved.
Indicators:
-
Inability to Speak or Cough: The person may clutch their throat and be unable to speak, cough, or breathe. Their face may turn red or blue as they struggle to breathe.
-
Clutching at the Throat: This is a universal sign of choking, indicating the person is aware of the obstruction and is struggling to clear it.
Immediate Action:
If the person becomes unresponsive and is not breathing, start CPR immediately. If the person is conscious but unable to breathe, perform the Heimlich maneuver (abdominal thrusts) to dislodge the object from the airway. If the person loses consciousness, begin chest compressions and rescue breaths. The compressions may help to dislodge the object while providing the necessary circulation of blood. After the object is expelled, continue monitoring the person's breathing and prepare to perform additional first aid if needed.
4. Heart Attack
Definition:
A heart attack, or myocardial infarction, occurs when blood flow to a part of the heart is blocked, often by a blood clot, leading to the death of heart muscle tissue. If untreated, a heart attack can lead to cardiac arrest, where the heart stops beating altogether.
Indicators:
-
Severe Chest Pain or Discomfort: The person may describe it as pressure, squeezing, fullness, or pain in the center or left side of the chest. The pain may radiate to the arms, back, neck, jaw, or stomach.
-
Shortness of Breath: The person may struggle to breathe or feel short of breath even while resting. This can accompany or precede chest discomfort.
-
Sweating and Nausea: The person may break out in a cold sweat, feel nauseated, or vomit. They may also feel lightheaded, dizzy, or unusually tired.
Immediate Action:
If the person becomes unresponsive and stops breathing, start CPR immediately. If they are conscious, call emergency services and keep them calm and still to reduce the strain on the heart. Administering CPR can help maintain circulation if the person's heart stops during the event. If available, give them aspirin (if they are not allergic and can chew it) to help thin the blood and reduce clotting. Monitor the person closely and be prepared to begin CPR if their condition deteriorates.
5. Drug Overdose or Poisoning
Definition:
A drug overdose or poisoning can depress or stop the respiratory system, leading to a lack of oxygen and potentially causing cardiac arrest. Overdoses often involve substances like opioids, sedatives, or alcohol, which can suppress breathing.
Indicators:
-
Altered Level of Consciousness: The person may appear drowsy, confused, or completely unresponsive. They may not respond to stimuli like shaking or loud noises.
-
Absence of Normal Breathing: The person may have slow, irregular breathing (respiratory depression) or may stop breathing altogether. Their skin may appear pale, blue, or ashen.
Immediate Action:
Administer CPR if the person is unresponsive and not breathing. After starting CPR, call emergency services and provide as much information as possible about the substance involved. If naloxone (Narcan) is available and you suspect an opioid overdose, administer it according to the instructions. Naloxone can temporarily reverse the effects of opioid overdoses, but CPR is still necessary if the person is not breathing or does not regain consciousness. Continue CPR until the person begins breathing on their own or emergency responders arrive.
CPR Techniques
CPR techniques involve a combination of chest compressions and rescue breaths. It is recommended the following CPR techniques:
-
Chest Compressions: Place the heel of one hand on the center of the person’s chest, just above the nipple line. Place your other hand on top and interlock your fingers. Push down to a depth of 2-3 inches at a rate of 100-120 compressions per minute. Ensure you allow the chest to fully recoil between compressions.
-
Rescue Breaths: After 30 chest compressions, give two rescue breaths. Pinch the person’s nose shut, cover their mouth with yours, and give a breath lasting one second. Watch for the chest to rise. Repeat the process.
-
Continuous Chest Compressions: If you are unable or unwilling to give rescue breaths, perform hands-only CPR with continuous chest compressions. This method is still effective in maintaining blood flow until help arrives.
Automated External Defibrillators (AEDs)
Automated external defibrillators (AEDs) are medical devices that can help restore a normal heartbeat during cardiac arrest. AEDs are designed for use by trained individuals, including medical professionals and bystanders who have received AED training. It is recommended the following steps for using an AED:
-
Turn on the AED and Follow the Voice Prompts: The device will guide you through the process.
-
Attach the Electrode Pads to the Person’s Chest: Follow the manufacturer’s instructions for proper placement.
-
Analyze the Person’s Heart Rhythm: The AED will assess the heart’s rhythm and advise if a shock is needed.
-
Deliver a Shock if Advised by the AED: Ensure no one is touching the person and press the shock button.
-
Continue CPR with Chest Compressions and Rescue Breaths: After the shock is delivered, resume CPR until emergency responders arrive.
By following these steps and using an AED, individuals can help increase the chances of survival for those who experience sudden cardiac arrest.
