pneumothorax
Let an agent explain pneumothorax and its types in general terms from clinical guidelines, describe symptoms, diagnosis and treatment approaches, and route anyone with symptoms to emergency care first.
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 pneumothorax and its types in general terms from clinical guidelines, describe symptoms, diagnosis and treatment approaches, and route anyone with symptoms to emergency care first.
The presence of air in the pleural space between the lung and the chest wall, causing partial or complete lung collapse, occurring spontaneously in primary form in otherwise healthy people, often tall young smokers, or secondary to lung disease, or from trauma or medical procedures, with variants when fluid, pus or blood also accumulate as hydropneumothorax, pyopneumothorax and haemopneumothorax; tension pneumothorax is a life-threatening emergency, and treatment ranges from observation to needle aspiration, chest drain and surgery.
What it is for: Not applicable; a medical condition.
It can be explain types and causes; relay diagnosis and treatment approaches; relay recurrence and prevention; route to emergency care.
Distinguishing features
Pleural air
Sudden chest pain and breathlessness
Tension form as emergency
Recurrence risk
What it looks like
Not a visible object; seen as lung collapse on chest imaging.
Physical character
primary spontaneous incidence: about 7-18 per 100000 men and 1-6 per 100000 women per year - estimates
How it is recognised
Air in the pleural space
Primary, secondary, traumatic, tension and mixed forms
Pleural effusion is fluid; emphysema is a lung tissue disease, though the registry lists it as parent
