A Beginner’s Guide to Cardiac Arrest & Defribillators

Cardiac arrest is a medical emergency that can happen to anyone, anywhere, at any time. It occurs when the heart stops beating unexpectedly and can happen without warning. If not treated immediately, it can lead to death. 

With this risk in mind, you must familiarise yourself with cardiac arrest and the first things you should do to save a person suffering from this health concern. Here is a brief guide you can start with.

What Is Cardiac Arrest?

Cardiac arrest is a sudden loss of blood flow to the heart. It happens when the heart stops beating and can no longer pump blood to the rest of the body. A cardiac arrest can be caused by various things, including heart disease, electrocution, and drowning. 

The likelihood of surviving a cardiac arrest depends on many factors, including the cause of the arrest, the speed of treatment, and the person’s overall health. However, CPR and early defibrillation are the most important survival factors.

What Are the Signs of a Cardiac Arrest?

The signs of a cardiac arrest can vary depending on the underlying cause, but there are some common warning signs that you should be aware of. 

  1. Sudden Collapse - This is often the first sign of a cardiac arrest. A person may suddenly fall to the ground with no warning.
  1. No Pulse - A person who has suffered a cardiac arrest will have no pulse. You can check for a pulse by feeling the carotid artery in the neck.
  1. No Breathing - A person who has suffered a cardiac arrest will also stop breathing. You can check for breathing by looking for the rise and fall of the chest.
  1. Loss of Consciousness - A person who has suffered a cardiac arrest will lose consciousness and will not be able to respond to stimuli.

If you see someone displaying these signs, it is crucial to call 000 immediately and start CPR. CPR can help to circulate the blood and keep the vital organs oxygenated until medical help arrives.

What Are the Ways to Survive a Cardiac Arrest?

There are two main ways to survive a cardiac arrest: CPR and an automated external defibrillator(AED).

1. Cardiopulmonary Resuscitation

Cardiopulmonary resuscitation (CPR) is a life-saving technique that is used to keep blood flowing to the heart and brain. Anyone can perform CPR, even if they are not trained medical professionals.

2. Automated External Defibrillator

An automated external defibrillator (AED) is a life-saving device that shocks the heart and restores a normal rhythm. AEDs are easy to use and can be found in many public places, such as airports and schools.

How Can You Choose an Automated External Defibrillator?

When faced with a cardiac emergency, every second counts. An automated external defibrillator (AED) can be the difference between life and death, so it’s important to choose the right one for your needs. Here are some factors to consider when selecting an AED: 

  1. Ease of Use - The AED should be easy to operate, even for someone who has never used one before. Look for an AED with clear, concise instructions and minimal steps.
  1. Portability - An AED should be lightweight and easy to transport. It may be difficult to move in an emergency if it's too heavy or bulky.
  1. Durability - The AED should withstand tough conditions, such as extreme temperatures or harsh weather.
  1. Battery Life - The AED should have a long-lasting battery, so it’s always ready to use.
  1. Warranty - Look for an AED with a comprehensive warranty that covers the device, batteries, and pads.

Final Thoughts

It is important to be aware of the signs of cardiac arrest and to know how to use a defibrillator properly to save a life. Every year, thousands of people die from cardiac arrest, but many of these deaths could be prevented if more people knew how to recognise the signs and use a defibrillator.
