CPR and AED Training

Problem

When someone has sudden cardiac arrest, the blocker is often not willingness to help but uncertainty about the first actions. Adults, children, and infants have different compression and breathing considerations; compression depth, recoil, rate, and pause time are easy to get wrong; and hesitation about using an AED can delay care. This skill turns those concerns into a practical teaching sequence that starts with scene safety and ends with a repeatable CPR rhythm.

How It Works and Limits

It first asks for the learning goal, patient group, and whether AED guidance is needed, then walks through the workflow: confirm the scene is safe, check responsiveness and breathing, call 120, request an AED, deliver compressions and rescue breathing, follow AED voice prompts, and continue the 30:2 cycle. It also flags common mistakes such as shallow compressions, incomplete chest recoil, excessive rescue breathing, and frequent pauses to check pulses, including Hands-Only CPR for learners who are not comfortable with rescue breathing.

Use it for education and first-aid learning, not as a substitute for hands-on training. It does not cover in-hospital ACLS, CPR instructor certification, academic research, or medical device development. Written guidance can build awareness, but skill requires periodic practice, and special cases such as pregnancy or obesity need tailored instruction.
