Question

1. the first step when the aed arrives:
2. where do you place the aed pads?
3. what must everyone do before a shock is delivered?
4. after a shock is delivered, what should you immediately do?
5. can you use an aed on a child? on an infant?

Explanation:

1. The first step is to turn on the AED, as this activates its voice prompts to guide subsequent actions.
2. For adults/older children, place one pad on the upper right chest (below the collarbone) and the other on the lower left side of the chest (below the armpit, on the ribcage).
3. Everyone must move away from the person, ensuring no physical contact, to avoid being shocked themselves and prevent interference with the AED's analysis.
4. Immediately resume high-quality cardiopulmonary resuscitation (CPR), starting with chest compressions.
5. AEDs can be used on children (ages 1-8): use child-specific pads if available, otherwise use adult pads with appropriate placement adjustments. For infants (under 1 year), use an infant-specific AED system if possible; if not, use child pads or adult pads with a dose attenuator, and place pads on the front and back of the chest.

Answer:

1. Turn on the AED device.
2. One pad on upper right chest (below collarbone), one pad on lower left chest (below armpit on ribcage).
3. Move away from the person, with no physical contact.
4. Immediately resume high-quality CPR, starting with chest compressions.
5. Yes, you can use an AED on a child (use child-specific pads if available); you can use an AED on an infant (preferably an infant-specific system, or child pads/adult pads with a dose attenuator, placed front and back of the chest).
