CPR — The Basics
Understand when CPR is needed and why early action saves lives.
Synopsis
Cardiopulmonary Resuscitation (CPR) is an emergency lifesaving technique used when a person’s heart has stopped beating or they have stopped breathing normally. Early CPR, combined with rapid emergency medical care, can significantly improve the chances of survival. While this lesson introduces the basic principles of CPR, practical hands-on training from a certified instructor is essential before attempting the technique.
Why this matters
Imagine witnessing a serious road crash. An injured person is lying motionless, not responding when spoken to and not breathing normally. Knowing what to do—and acting quickly—can help keep oxygen flowing to the brain and other vital organs until professional medical help arrives.
Expected outcome
You will be able to recognise situations where CPR may be required, take the correct steps before starting CPR, and understand the role of chest compressions and AEDs until professional help arrives.
Learning objectives
After completing this lesson learners should be able to:
- Understand what CPR is and why it is important
- Recognize situations where CPR may be required
- Learn the basic steps to take before starting CPR
- Understand the importance of chest compressions and Automated External Defibrillators (AEDs)
- Recognize the importance of formal CPR training
Introduction
Imagine witnessing a serious road crash. An injured person is lying motionless. They are not responding when spoken to and do not appear to be breathing normally. These are frightening moments. Knowing what to do—and acting quickly—can help keep oxygen flowing to the brain and other vital organs until professional medical help arrives. CPR is one of the most valuable emergency skills anyone can learn. However, CPR is a practical skill that requires proper training. This lesson provides an overview to help you understand when CPR may be needed and why early action is so important.
What is CPR?
CPR stands for Cardiopulmonary Resuscitation. It is an emergency procedure that combines chest compressions and rescue breaths (when trained and appropriate). The aim is to maintain blood circulation and oxygen delivery to vital organs until emergency medical professionals can take over.
When Might CPR Be Needed?
CPR may be required if a person is unresponsive, is not breathing normally, or shows no signs of life. Following a road crash, these situations can occur due to severe injuries or other medical emergencies. Never assume someone has died simply because they are unconscious. Immediate assessment and rapid activation of emergency services are essential.
Step 1 — Ensure the Scene is Safe
Before approaching the injured person, check for moving traffic, look for fire or smoke, watch for leaking fuel, stay clear of damaged electrical systems and make sure there are no immediate dangers.
Remember
Do not place yourself at risk.
Step 2 — Check Responsiveness
Approach the person safely. Speak loudly and clearly — for example, “Can you hear me?” If there is no response, gently tap the person’s shoulder (if safe to do so). Do not shake the person violently.
Step 3 — Call for Emergency Help
If the person is unresponsive, call 112 immediately. If another bystander is present, ask them to call while you remain with the injured person. Request an ambulance as quickly as possible. Early emergency activation saves valuable time.
Step 4 — Check for Normal Breathing
Look for normal breathing. Occasional gasping or irregular breaths are not considered normal breathing. If the person is not breathing normally, emergency action is required.
Chest Compressions
Chest compressions help circulate blood through the body when the heart is no longer pumping effectively. Proper CPR technique requires practical training. If you have received recognised CPR training, follow your training while waiting for emergency medical services. If you are not trained, follow the instructions provided by the emergency dispatcher. In many situations, the dispatcher can guide you until professional responders arrive.
Automated External Defibrillators (AEDs)
An Automated External Defibrillator (AED) is a portable device designed to analyse the heart’s rhythm and, when appropriate, deliver an electrical shock. AEDs are increasingly available in airports, railway stations, shopping malls, corporate offices, educational institutions and sports complexes. AEDs provide clear voice instructions and are designed for use by members of the public while waiting for trained responders. If an AED is available, ask someone to bring it immediately while emergency services are on the way.
Continue Until Help Arrives
If CPR has been started, continue until emergency medical professionals take over, the person begins breathing normally and becomes responsive, the scene becomes unsafe, or you are physically unable to continue. Remain calm and follow any instructions provided by emergency dispatchers.
Common Mistakes to Avoid
Do not delay calling emergency services. Do not leave the person alone unnecessarily. Do not assume occasional gasping means normal breathing. Do not crowd around the injured person. Do not attempt CPR techniques you have not been trained to perform without guidance from emergency services. Whenever possible, seek formal CPR certification to build confidence and practical skills.
Did you know?
Early CPR and rapid defibrillation using an AED, when appropriate, can significantly improve survival in certain cardiac emergencies. This is why many workplaces, airports and public facilities now install AEDs alongside first-aid equipment.
Real-world scenarios
Vikram responds to a motorcycle collision
Vikram witnesses a collision involving a motorcycle. The rider is unconscious and does not appear to be breathing normally.
→ What should Vikram do?
Show suggested response
After ensuring the scene is safe, Vikram asks another bystander to call 112 while he remains with the injured person. The emergency dispatcher guides him over the phone until trained ambulance personnel arrive. Because emergency action began quickly, valuable time was not lost while waiting for professional medical care.
Key takeaways
- CPR is an emergency lifesaving procedure.
- Always ensure the scene is safe before helping.
- Call 112 immediately if a person is unresponsive and not breathing normally.
- Follow recognised CPR training or dispatcher instructions.
- AEDs are designed to assist during certain cardiac emergencies.
- Early action can improve the chances of survival.
