Students in Vancouver practice CPR in a file photo. People used to be told to give two breaths for every 15 chest compressions. That formula changed in 2005 to two breaths for every 30 compressions. But animal research has suggested that chest compressions alone may be just as good, perhaps because rescuers continue pumping the victim's heart rather than stopping to give mouth-to-mouth breaths.

When someone collapses suddenly, mouth-to-mouth rescue breathing may not be necessary and could lower the chances of survival, researchers...
