This lab shows an open beekeeper's sting kit next to a simplified patient monitor. Dragging the reaction severity slider changes whether the sting stays a normal local reaction or escalates toward anaphylaxis; dragging minutes since sting scrubs through the first twenty minutes after the sting, the window where most dangerous reactions declare themselves.
Anaphylaxis after a sting typically begins within minutes, which is why UK guidance is to use an epinephrine auto-injector immediately at the first sign of a severe reaction and call 999 — waiting to "see if it gets worse" is the single most common fatal delay.
An open sting kit sits beside a simplified patient monitor: scrub through the minutes after a sting, dial in how severe the reaction is, and step through the real five-step protocol to see which kit item actually turns a reaction around.
Reaction severity and elapsed time drive swelling, spreading hives and airway narrowing on the patient figure. Antihistamines only help mild–moderate reactions; only epinephrine, given at the anaphylaxis stage, visibly reverses swelling and reopens the airway.
Set severity and scrub the timeline, then step through the protocol select. Each step highlights the matching kit item with a glowing ring; choosing epinephrine on a severe reaction launches an auto-injector animation and starts recovery.
UK first-aid guidance is unambiguous: at the first sign of a severe allergic reaction, give epinephrine immediately and call 999 — waiting for antihistamines to work first is a well-documented cause of preventable deaths.
