Your phone hits 1%, and you feel it almost physically.
That small flash of red changes your whole priority for the next ten minutes. You're scanning the room for a charger, borrowing a cable, rearranging your afternoon around the nearest wall socket, because a dead phone feels like something that needs fixing immediately.
Which makes it worth sitting with a quieter question for a moment.
Somewhere near your reception or main entrance, there's probably a yellow cabinet on the wall. Inside it is a device that doesn't need to make calls or send emails; it just needs to work once, on the worst day someone in your building will ever have. And if you're being honest, you probably couldn't say when someone last opened that cabinet and confirmed the pads are in date, the battery has charge, and the unit is actually ready.
A peer-reviewed study published in Scientific Reports examined over 23,000 public AEDs in Seoul across five years of on-site inspections and found that roughly one in six were not ready for use. The most common reason was expired electrode pads, something a thirty-second check would catch.

The underlying problem isn't geographic, and maintenance habits drift in the same way wherever a device is installed and left unchecked. Industry professionals in the UK have raised similar concerns, particularly around the gap between funding the purchase of AEDs and funding their ongoing maintenance.
Having an AED on site is only half the job. The other half looks like a Tuesday morning habit, a name on a rota, a check that takes less time than finding your charger cable, pads in date, battery charged, cabinet functioning. Thirty seconds and you know where you stand.

Readiness isn't about assuming the worst will happen; it's about making sure your community isn't part of that one in six if it does. 💚
