Escalation and paging

An alert never just sits on a screen. The server runs a ladder for every critical alert:

When	Who is paged	Why
The alert is raised	Every nurse phone on the ward	Someone near should go now
Not acknowledged within 30 s	Nurses and the charge nurse	It is escalated: the shift lead must know
Still not acknowledged, every 2 minutes	Both again	Reminders until a person owns it

Warnings (soft alerts) appear on the screens only and page nobody. Acknowledging stops the ladder.

Every page is on the record

Each page is written to the journal with how many phones it reached. Zero is recorded too, and the server warns: “nobody reached” is never silent. The station can see how many phones of each role are connected.

Why the ladder lives on the server

One place to audit it and one place to change it: a different ward can get a different ladder without updating any phone. Phones are reached over the building’s own network; no cloud push service is involved.
