Terry BrownFeb 20, '24

February is Heart Month, the ideal time to focus on increasing awareness of heart health and motivating individuals to embrace healthier living habits. This month serves as an opportunity to educate about cardiac arrest, heart disease risks, advocate for preventative actions, and motivate people to enhance their heart health.

When faced with a cardiac arrest, every second counts. It's a dire emergency where the heart suddenly stops beating, cutting off blood flow to the brain and other vital organs. You've got the power to make a difference, and knowing the right first aid steps could be a game-changer.

The statistics are stark: many victims of cardiac arrest don't make it to the hospital in time. On average, people wait 3 hours before seeking help. But with prompt action and medical attention, you can significantly boost survival chances and minimize heart damage.

Recognizing the symptoms early is crucial, from the intense chest pain to subtle signs like nausea or an unshakeable sense of dread. Being prepared to act could save a life.

Understanding Cardiac Arrest

What Is Cardiac Arrest?

Cardiac arrest is a severe medical emergency characterized by the sudden loss of heart function. When cardiac arrest strikes, the heart ceases to beat effectively, halting blood flow to vital organs including the brain. Unlike a heart attack, which is caused by a blockage preventing blood to the heart muscle, cardiac arrest usually stems from an electrical disturbance that disrupts the heart's rhythm. This abrupt change can cause death if not treated immediately. If someone does experience cardiac arrest, their survival heavily depends on swift first aid and the initiation of CPR.

Causes of Cardiac Arrest

Cardiac arrest can occur due to various reasons, not just heart-related issues. Below, you'll discover some of the primary causes:

  • Ventricular fibrillation: An erratic and rapid heartbeat thwarting proper blood pumping
  • Untreated heart attack: Can trigger an electrical malfunction leading to cardiac arrest
  • Congenital heart disease: Those born with heart anomalies are at heightened risk
  • Electrocution: Electrical shocks can disrupt cardiac rhythm
  • Suffocation: Lack of oxygen may lead to cardiac arrest
  • Drug overdose: Certain substances can have severe cardiac effects

Recognizing the cause is critical as it may influence the type of first aid and long-term treatment one requires.

Signs and Symptoms

The signs of impending cardiac arrest can occur suddenly and require urgent attention. Key symptoms include:

  • Sudden collapse: Indicative of a lack of pulse or consciousness
  • Unresponsiveness: No reaction to questions or stimulation
  • Absence of breathing or agonal breathing: Gasping, shallow breaths
  • Chest pain or discomfort: Previously, if it was a precursor to the event
  • Weakness or fatigue: Possibly coupled with other symptoms

Look for these warning signs and prepare to administer immediate CPR if they occur. Remember, recognizing and responding to these symptoms decisively can dramatically improve survival rates.

Performing Cardiopulmonary Resuscitation (CPR)

CPR, or Cardiopulmonary Resuscitation, is a critical life saving skill that you can perform in an emergency when someone's heart has stopped beating.

Importance of CPR in Cardiac Arrest

Immediate CPR can dramatically improve the chances of survival after a cardiac arrest. When the heart stops, the lack of oxygenated blood can cause brain damage within minutes. By performing CPR, you're effectively circulating blood that carries oxygen to the brain and other vital organs, providing a lifeline until professional medical help arrives. Immediate CPR can double or even triple a person's chance of survival.

Steps of CPR

To perform CPR, follow these crucial steps:

  • Ensure the scene is safe, then place the person on a firm, flat surface.
  • Call for medical assistance immediately. Time is of the essence.
  • Kneel beside the person's neck and shoulders.
  • Place the heel of one hand over the center of the person's chest, between the nipples.
  • Put your other hand on top of the first, interlocking fingers.
  • Keep your elbows straight and shoulders directly above your hands.
  • Press down hard and fast, with compressions at least 2 inches deep, but not exceeding 2.4 inches, at a rate of 100 to 120 compressions per minute. This pace matches the beat of the song "Stayin' Alive".
  • Allow the chest to rise completely before the next compression.

It is strongly recommended to take a First Aid, CPR & AED Training Course through SOS Emergency Response Technologies to learn these vital skills and help save lives.

Prestan CPR Training Manikins

Prestan manikins are renowned for their role in CPR training, offering realistic and durable models for learners to practice lifesaving techniques. Designed to simulate human anatomy accurately, these manikins provide immediate feedback on the quality of compressions and breaths, ensuring that trainees learn the correct force and depth required for effective CPR. With features like easy-to-clean surfaces and optional feedback devices, Prestan manikins are an invaluable tool in emergency response training. Their versatility makes them suitable for a wide range of educational settings, from professional healthcare facilities to community CPR classes, enhancing the preparedness of individuals to respond to cardiac emergencies.

Using an Automated External Defibrillator (AED)

Role of AED in Cardiac Arrest

An AED is a lifesaving device crucial if a cardiac arrest. It checks the heart's rhythm and sends an electric shock to the heart to try to restore a normal rhythm. This treatment is known as defibrillation. When a person experiences cardiac arrest, their heart's electrical activity becomes chaotic. The timely use of an AED can correct this irregular rhythm, possibly restarting the heart.

  • AEDs increase the chance of survival when used within the first few minutes of a cardiac arrest.
  • Coordinated with CPR, they provide a comprehensive emergency response.
  • AEDs come with built-in instructions and voice prompts, so requiring minimal training to use effectively.

How to Use an AED

Using an AED involves a series of steps you'll need to follow:

  1. First, call for emergency services. If you're alone, don't delay in using the AED.
  2. Turn on the AED. It's designed to give you voice instructions.
  3. Bare the chest of the person in need and attach the AED pads.
  4. Once attached, step back and allow the AED to analyze the heart's rhythm.
  5. If a shock is advised, ensure nobody is touching the person and press the shock button.
  6. Continue with CPR until emergency services arrive or the person regains consciousness.

These instructions act as a guideline and hands-on training is highly recommended to build confidence and efficiency in using an AED.

First Aid Techniques for Cardiac Arrest

When confronted with cardiac arrest, the correct first aid techniques can mean the difference between life and death. Your immediate actions are vital and following these steps can help increase the chances of survival.

Calling Emergency Services

Without Delay, the moment you suspect someone is suffering from cardiac arrest, you need to call the emergency services. Clearly communicate the condition and location of the victim to ensure a swift response. While you're waiting for help to arrive, prepare to initiate cardiac first aid.

Clearing the Airway

An open and clear airway is crucial to ensure that oxygen can reach the lungs. If the victim is unresponsive:

  • Gently place one hand on the forehead and two fingers from the other hand under the chin.
  • Carefully tilt the head back to lift the chin, which prevents the tongue from blocking the airway.
  • Check for normal breathing, looking for chest movement and feeling for breath on your cheek.

If you find that the victim is not breathing normally, or only gasping, proceed with chest compressions immediately.

Administering Chest Compressions

Chest compressions help maintain vital blood flow to the heart and brain when the heart has stopped beating. Time and technique are crucial:

  • Kneel beside the victim's chest.
  • Place the heel of one hand on the centre of the victim's chest with the heel of the other hand on top, interlocking your fingers.
  • With your arms straight, press down hard and fast, at a rate of 100 to 120 compressions per minute.
  • Press down to a depth of about 5-6 centimetres and allow the chest to return to its normal position between compressions.

Quick and deep Compressions maximize the blood flow and keep the brain and organs alive. Keep performing CPR until emergency services take over or the person starts to show signs of life.

Remember, deploying these first aid techniques with confidence and precision is the key to giving someone in cardiac arrest a fighting chance. Your readiness to act can save a life.
