Any attempt at CPR is better than no attempt. Hands-Only™ CPR performed by a bystander has been shown to be as effective as conventional CPR with mouth-to-mouth breaths in the first few minutes of an out-of-hospital sudden cardiac arrest. Conventional CPR may be better than Hands-Only™ CPR for certain victims, such as infants and children, adults who experienced an un-witnessed cardiac arrest, or victims of drowning.
