The main elements of the adult procedure for CPR (Cardiopulmonary Resuscitation) with an AED (Automated External Defibrillator) are as follows:
1. Check for responsiveness: Before starting CPR, assess the victim for responsiveness by tapping the person's shoulder and shouting, "Are you okay?" If there is no response, proceed to the next step.
2. Call for help: Immediately call for emergency medical services (EMS) or ask someone nearby to call for help. It is crucial to activate the emergency response system as soon as possible.
3. Start chest compressions: Position the person on their back on a firm surface. Kneel beside the person's chest. Place the heel of one hand on the center of the person's chest, between the nipples. Place the other hand on top of the first hand and interlace the fingers. Keep your arms straight and position your shoulders directly over your hands. Begin compressions by pushing hard and fast, at a rate of at least 100-120 compressions per minute. Allow the chest to fully recoil between compressions.
4. Provide rescue breaths: After performing 30 chest compressions, give two rescue breaths. Tilt the person's head back slightly, lift their chin, and pinch their nose closed. Make a complete seal with your mouth over the person's mouth and deliver a breath that makes the chest rise. Each breath should last about one second.
5. Attach the AED: If an AED is available, turn it on and follow the voice prompts or visual instructions provided by the device. Open the person's shirt to expose their chest and attach the AED pads to the person's bare skin. Place one pad on the upper right chest, just below the collarbone, and the other pad on the lower left side of the chest, below the armpit.
6. Analyze the heart rhythm: Once the AED pads are attached, the device will analyze the person's heart rhythm. Ensure that no one is touching the person during the analysis.
7. Follow AED prompts: Based on the analysis, the AED will provide voice prompts or visual instructions. Follow the AED's prompts precisely. If a shock is advised, make sure no one is touching the person, ensure everyone is clear, and deliver the shock by pressing the designated button.
8. Resume CPR: After delivering the shock, immediately resume CPR, starting with chest compressions. Continue to follow the AED's prompts and perform CPR until help arrives or the person shows signs of life.
