skip the mouth-to-mouth

From the American Heart Association:

...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.

Experts hope bystanders will now be more willing to jump in and help if they see someone suddenly collapse. Hands-only CPR is simpler and easier to remember and removes a big barrier for people skittish about the mouth-to-mouth breathing.
