ischemia
Let an agent explain ischaemia and its causes and forms in general terms, relay warning signs and emergency guidance from medical bodies, describe diagnosis and treatment as documented, and route personal questions to clinicians.
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 explain ischaemia and its causes and forms in general terms, relay warning signs and emergency guidance from medical bodies, describe diagnosis and treatment as documented, and route personal questions to clinicians.
A restriction of blood supply to tissue causing a shortage of oxygen and nutrients, affecting organs such as the heart, brain, kidney, retina, bone and limbs, and arising from blocked or narrowed vessels, low blood pressure, compression as in compartment syndrome, or other causes; ischaemia can lead to necrosis if prolonged, is a medical emergency in many forms, and this entry gives general information only, not personal medical advice.
What it is for: Restricted blood supply to tissue.
It can be explain causes and forms; relay warning signs and emergency guidance; describe diagnosis and treatment generally; route personal questions.
Distinguishing features
Vascular cause
Oxygen deficiency
Time-critical
Organ-specific
What it looks like
Not visible externally in most forms; pale, cold or painful tissue in limbs.
How it is recognised
Insufficient blood supply
Organ-specific forms
Hypoxia is low oxygen from any cause; infarction is resulting tissue death
