A ward patient had a chest drain inserted & quickly went into pulmonary oedema. We know this as re-expansion pulmonary oedema. Solution usually involves clamping the drain to prevent further drainage (if it's an effusion). But why does it happen? 
It occurred to me during my shift tonight that I don't understand why. It seems I am not alone. Often it's just a radiological finding, but I've seen patients in significant distress from it & it can apparently be be fatal.
But no one really knows why it happens.

#NotATweetorial Forgive this not being well referenced, I'm at work & just randomly reading around without making notes but a leading theory is about capillary permeability secondary to endothelial damage. Akin to an ARDS picture. Still not sure why though.
