You’re in a busy restaurant during dinner service. A man at the next table suddenly stands up, grabs his throat, and looks panicked.

Adult Collapse at Home Alone Rescuer

Adult Collapse in Public
You’re at a busy public gym on a weekday evening. Music is playing, people are moving between machines, and a man in his 50s suddenly collapses near the cardio area. For a second, nobody reacts.

Child Collapse at School, AED Available
It’s late morning at school, and children are lining up after recess. A 7-year-old suddenly drops to the ground near the playground gate.

You’re in a busy shopping mall on a Saturday afternoon. A man in his 60s suddenly collapses near the entrance. People stop, stare, and start talking all at once.

An AED is mounted on the wall nearby.
