Pulmonology 2

After 2 days of physic, Ollie's lung has still not recovered.  They were unsure whether it was an effusion or a collapsed lung, so they poked around a bit and couldn't find fluid.  So it has to be a collapsed lung, right?  They will do bronchoscopy later this morning and try and see if they can find a plug that blocks the main stem bronchi and prevents the lung from inflating.
