Cardiac Arrest

TL;DR

Sudden cessation of heart function, requiring immediate resuscitative efforts.

What is Cardiac Arrest?

Cardiac arrest is a sudden loss of heart function, breathing, and consciousness, often resulting from an electrical disturbance in the heart that disrupts its pumping action. This leads to a cessation of blood flow to the brain and other vital organs. Cardiac arrest is a medical emergency that requires immediate intervention to improve the chances of survival and reduce the risk of permanent damage. First aid for cardiac arrest involves performing cardiopulmonary resuscitation (CPR) and using an automated external defibrillator (AED) if available.

The first aider should call emergency services immediately, then start CPR by giving chest compressions at a rate of 100-120 per minute and a depth of 5-6 cm for adults. If an AED is available, it should be used as soon as possible, following the device's voice prompts. The AED analyses the heart's rhythm and, if necessary, delivers a shock to help restore a normal heart rhythm. Continuous cycles of CPR and AED use should be maintained until professional medical help arrives. The rapid response to cardiac arrest, including effective CPR and defibrillation, significantly increases the likelihood of survival and recovery.

First Aid for Cardiac Arrest

• Call for Help: Dial emergency services immediately.
• Begin CPR: Perform chest compressions and rescue breaths.
• Use an AED: Apply an Automated External Defibrillator if available.
• Continue Until Help Arrives: Keep performing CPR and using the AED until professional help takes over.

Takeaway to remember

Cardiac arrest occurs when the heart suddenly stops beating, leading to a loss of blood flow to the brain and other vital organs. Immediate intervention is critical to increase the chances of survival.
