You can skip the mouth-to-mouth breathing and just press on the chest to save a life. In a major change, the American Heart Association said Monday that hands-only CPR — rapid, deep presses on the victim's chest until help arrives — works just as well as standard CPR for sudden cardiac arrest in adults.
A child who collapses is more likely to primarily have breathing problems — and in that case, mouth-to-mouth breathing should be used. That also applies to adults who suffer lack of oxygen from a near-drowning, drug overdose, or carbon monoxide poisoning. In these cases, people need mouth-to-mouth to get air into their lungs and bloodstream.
Sayre said the association took the unusual step of making the changes now — the next update wasn't due until 2010 — because three studies last year showed hands-only was as good as traditional CPR. Hands-only will be added to CPR training.
For those (like me) who probably will not go to a CPR certification class in the near future.
