Concept:
For adults and adolescents in a life-threatening emergency, activate emergency medical services (EMS) immediately (call 911 or your local emergency number) to get professional help on the way as soon as possible.
– Example (one clear): A 64-year-old man suddenly collapses at a gym.
By-stander calls 911 right away and starts chest compressions while another person retrieves an AED; EMS arrives shortly after.

Concept:
In adults/adolescents, prompt EMS activation should not be delayed by other actions; call for help while you begin care.
– Brief example: A teenager collapses; a bystander immediately calls 911 and begins CPR.
