Knowing how to perform CPR is one of those "musts" that you might not think of when you're dealing with a severe food allergy. Yes, it's unlikely that you'll ever need to use it. But in the event of an anaphylactic reaction or a severe asthma attack, you may need to assist a friend or family member before emergency services can reach you. Learning CPR techniques now and reviewing them periodically can mean they'll be second nature when you need them.

The American Heart Association's new guidelines for performing adult CPR are simpler than ever: no more rescue breathing. Take a few minutes to check out the brand-new revised guidelines for Hands-Only CPR for adults and review (or learn) how to provide Child CPR.
