Q

common complications include pneumothorax and hemorrhage

A

bronchoscopy

also transient hypoxemia

remember “common” in this case is still less than 1% chance

pulmonary angiography

20
Q

A

free air under the diaphragm

21
Q

MC etiology for this CXR finding is pleural effusion

A

costophrenic blunting

could also be due to
hemothorax, PE, pleural abscess, ect.

22

why would a procalcitonin be acquired when evaluating bronchitis

A

to assess whether the cause is bacterial or non bacterial

23

used to assess or diagnose neuromuscular problems affecting respiratory function

A

spirometry

also used for prevention of pneumonia post surgery or post trauma
