embolism
Let an agent explain embolism and its kinds in general terms from clinical sources, identify emergency presentations, describe causes, treatment and prevention, distinguish embolism from thrombosis, 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 embolism and its kinds in general terms from clinical sources, identify emergency presentations, describe causes, treatment and prevention, distinguish embolism from thrombosis, and route personal questions to clinicians.
The blockage of a blood vessel by an embolus, a mass such as a blood clot, air bubble, fat globule, amniotic fluid or tumour fragment carried in the bloodstream from elsewhere, causing pulmonary embolism when clots lodge in the lungs, arterial embolism including stroke when emboli from the heart as cardiac embolism or from arteries block arteries, paradoxical embolism when a venous clot crosses a heart defect, and rare forms such as air embolism, amniotic fluid embolism and embolism complicating abortion or childbirth; embolism is a medical emergency treated with anticoagulants, thrombolysis or removal.
What it is for: Not applicable; a medical condition.
It can be explain kinds and mechanism; identify emergencies; relay treatment and prevention; route personal questions.
Distinguishing features
Travelling embolus
Sudden vessel blockage
Emergency presentation
Many embolus types
What it looks like
Not a visible object; a blocked vessel and the affected organ.
Physical character
venous thromboembolism incidence: about 1-2 per 1000 per year
untreated pulmonary embolism mortality: up to about 30 percent
amniotic fluid embolism: about 1 in 40000 deliveries - rare
How it is recognised
Vessel blockage by a travelling mass
Pulmonary, arterial, cardiac, paradoxical, air, fat, amniotic fluid and obstetric embolism
Thrombosis is a clot forming in place; an aneurysm is a vessel bulge; an infarction is the resulting tissue death

What the second pass must settle

- How should clinical guidelines be linked?
- The registry entry has merged aliases naming embolus types and obstetric contexts; should they be split off?
