How it works

From the shock type, through the physiology, to the monitor.

Every shock reaches the same place — a falling blood pressure — but by a different route. Pick a shock type on the left and watch it flow through the underlying physiology (the middle) to the numbers you read on the monitor (the right). The couplings are real; nothing here is a scripted curve.

Click a shock type to trace its cascade left → right. Green + raises · red − lowers the thing it points to.

Pick a shock type above. Each one drives the physiology differently — watch which mediators it hits, and whether the heart rate rises (compensation) or, uniquely for neurogenic shock, falls.

Shock type Circulation (pump · tank · pipes) Oxygenation On the monitor

All five end in a falling blood pressure — but hypovolaemic drains the tank, cardiogenic weakens the pump, obstructive blocks filling, and distributive opens the pipes. The heart-rate response is the tell: it rises to compensate in every type except neurogenic, where lost sympathetic tone leaves it paradoxically slow. That contrast isn't scripted — it falls out of the couplings above.
