An AED (Automated External Defibrillator) should be used immediately when a person collapses and is unresponsive, not breathing normally, and has no pulse, indicating sudden cardiac arrest. The AED analyzes the heart's rhythm and delivers an electric shock if needed to restore a normal heartbeat. If someone is conscious, breathing normally, or has a pulse, an AED should not be used. Additionally, AEDs should be used carefully if the victim has a Do-Not- Resuscitate (DNR) order or there are environmental hazards like water or flammable substances.
When to Use an AED
- Sudden cardiac arrest with no response, no normal breathing, and no pulse.
- After about two minutes of CPR, an AED can be attached to maximize effectiveness.
- Situations like drowning or severe electric shock causing cardiac arrest.
- The device itself instructs and guides responders through the process.
When Not to Use an AED
- If the person is conscious, breathing normally, and has a pulse.
- In wet or waterlogged environments unless the victim is moved to a dry area.
- Around flammable substances or gases.
- On victims with traumatic cardiac arrest related to severe injuries.
- If a valid DNR order is present.
- During childbirth or when specific medical exceptions apply.
Using an AED quickly in a cardiac arrest situation increases survival chances by restoring the heart’s normal rhythm before permanent brain and organ damage occurs.
