Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent route possible hypertensive emergencies to urgent care, give general sourced information on blood pressure, measurement and prevention, and refer individual questions to clinicians.

A long-term condition in which blood pressure in the arteries is persistently raised, commonly defined as 140/90 mmHg or higher in many guidelines and 130/80 mmHg or higher in some, and a major risk factor for stroke, heart disease and kidney disease; it often has no symptoms. Pulmonary hypertension is a different condition.

What it is for: A common health condition relevant to prevention and public health.

It can be recognise emergency warning signs; measure blood pressure correctly at home; find official guidance on lifestyle and screening; prepare questions for a clinician.

Distinguishing features

Often symptomless

Major cardiovascular risk factor

Diagnosed by repeated measurements

Thresholds differ between guidelines

What it looks like

Usually invisible; detected by blood pressure measurement.

Physical character

common diagnostic threshold: 140/90 or 130/80 mmHg - depends on the guideline

How it is recognised

Readings shown as systolic over diastolic in mmHg

Home and clinic monitors

Low blood pressure is hypotension
