How to Handle Cardiac Arrest 

TIps on life saving critical steps to take in the event of a cardiac arrest.  
Heart sign related to cardiac arrest
 
Imagine this: You’re in the office, perhaps finishing up a meeting or chatting with colleagues, when suddenly someone collapses. They’re unresponsive, not breathing normally, and it’s clear something is seriously wrong. This is a cardiac arrest, and in that instant, every second counts. Knowing what to do could be the difference between life and death. 
 
What Is Cardiac Arrest? 
Cardiac arrest occurs when the heart suddenly stops pumping blood around the body, usually due to an electrical malfunction in the heart. This is not the same as a heart attack, which happens when blood flow to the heart is blocked. During cardiac arrest, the person will lose consciousness almost immediately and won’t be breathing normally or at all. Without intervention, death can occur within minutes. 
 
Step 1: Recognise the Signs 
 
Time is critical. The first step is recognising that someone is in cardiac arrest. Look for these signs: 
Sudden Collapse: The person falls to the ground without warning. 
Unresponsiveness: They don’t respond when you talk to or shake them. 
No Normal Breathing: Their breathing may be irregular, gasping, or absent. 
If you notice these signs, act immediately. Don’t wait or assume someone else will take charge. 
 
Step 2: Start CPR Immediately 
 
While waiting for emergency services, begin Cardiopulmonary Resuscitation (CPR). This helps keep blood and oxygen circulating to vital organs until professional help arrives. Here’s how to do it: 
Place the Heel of Your Hand: Position one hand in the centre of the person’s chest, then place your other hand on top and interlock your fingers. 
Push Hard and Fast: Press down firmly and quickly, aiming for a depth of 5-6 cm and a rate of 100-120 compressions per minute. Think of the rhythm of “Stayin’ Alive” by the Bee Gees – it’s the perfect pace. 
Don’t Stop: Continue chest compressions without pausing. If someone else is trained in CPR, take turns every 2 minutes to avoid fatigue. 
 
Step 3: Call 999 
 
As soon as you’ve identified cardiac arrest, call 999 and send for a defibrillator. Tell the operator that the person is in cardiac arrest and provide your location as clearly as possible. If there are others around, delegate this task to someone specific by pointing at them and saying, “You, call 999!” 
 
Step 4: Use an Automated External Defibrillator (AED) 
 
If there’s an AED nearby, send someone to get it. AEDs are often located in workplaces, shopping centres, and public areas. Once you have the device: 
Turn on the AED: It will provide voice prompts to guide you. 
Attach the Pads: Place the pads on the person’s bare chest as shown in the diagrams on the device or pads. 
Follow Instructions: The AED will analyse the heart’s rhythm and advise whether to deliver a shock. If needed, press the button to deliver the shock, and then continue CPR. 
Don’t worry about making a mistake – AEDs are designed to be user-friendly and will only deliver a shock if it’s needed. 
 
Step 5: Continue Until Help Arrives 
 
Keep performing CPR and follow the AED’s instructions until emergency services arrive. It’s exhausting, but your efforts are critical. You’re giving the person the best chance of survival. 
 
What Happens Next? 
 
When the paramedics arrive, they’ll take over and continue advanced care. The quicker you’ve responded, the better the outcome. It’s common to feel a rush of emotions – relief, exhaustion, anxiety – but remember that you did everything possible to help. 
 
Why Speed and Training Matter 
 
According to the Resuscitation Council UK, every minute without CPR and defibrillation reduces the chances of survival by 10%. In workplaces, having trained first aiders and accessible AEDs can make a life-saving difference. 
 
Get Trained and Be Prepared 
 
It’s not just about knowing what to do but being prepared to act. At First Aid Safety, we provide comprehensive training in CPR, AED use, and first aid, tailored for businesses and organisations. Being equipped with these skills means you’ll be ready to respond effectively in an emergency, no matter where or when it happens.
