CPR and AEDs are both crucial tools in treating sudden cardiac arrest, but they address different aspects of the emergency. CPR (Cardiopulmonary Resuscitation) manually maintains circulation and oxygen flow to the brain and heart until the heart restarts or professional help arrives. AEDs (Automated External Defibrillators) are devices that analyze the heart's rhythm and deliver an electrical shock to restore a normal heart rhythm.
CPR Purpose:
To manually keep blood flowing to the brain and heart when the heart has stopped beating.
Procedure:
Involves chest compressions and rescue breaths (if trained to do so).
Effectiveness:
CPR alone can increase survival rates to around 20-30%.
When to use:
If a person collapses and is unresponsive, not breathing, or breathing only gasps, immediately call emergency services and start CPR.
AED Purpose:
To analyze the heart's rhythm and deliver a shock (defibrillation) if necessary to restore a normal heartbeat.
Procedure:
Involves placing pads on the chest, following the device's instructions, and delivering a shock when prompted.
Effectiveness:
AEDs dramatically improve survival rates when used in conjunction with CPR, potentially doubling the chances of survival.
When to use:
As soon as available, attach it to the person and follow instructions.
Key Differences:
Purpose: CPR sustains life; AED restores a normal heart rhythm.
Method: CPR is manual, while AED is a device.
Timing: CPR should be started immediately ( Preferably within 2 mins), while AED should be used as soon as it is available (Preferably within 4 mins).
In summary, CPR and AEDs work together to provide the best chance of survival for someone experiencing sudden cardiac arrest. CPR keeps blood flowing while an AED attempts to recorrect the heart's rhythm.
