A First Aid Guide

1. Give 30 chest compressions

Push hard and fast in the middle of the chest. Push at least 2 inches deep and at least 100 compressions per minute. Make sure the person is on a firm, flat surface.

2. Give 2 rescue breaths

Tilt the head back and lift the chin up to make sure the airway is clear. Pinch the nose shut and make a complete seal over the person's mouth with yours. Make sure to use a mouth barrier device, if possible. Blow in for about 1 second to make the chest clearly rise. Give rescue breaths one after another. If the rescue breaths don't make the chest rise, make sure their airway is cleared properly, then try again.

3. Don't stop

Continue repeating steps 1 and 2. Stop only if:

- You find an obvious sign of life, like breathing

- An AED is ready to use

- Another trained responder or EMS personnel take over

- You are too physically exhausted to continue

- The scene becomes unsafe

4. Use an AED (if available)

If an AED becomes available, use that to try to revive the person.

5. If breaths don't make the chest rise:

Retilt the head to make sure the airway is properly cleared. If that still doesn't solve the problem, treat the person for unconscious choking.
