Indications: broad (respiratory or cardiac disease, tube positioning, trauma) Characteristics of a good chest x-ray (PIER): Projection (AP, PA, lateral, lateral decubitus): heart will appear bigger on AP, but not by much, AP is better for intubated/sick patients, two views is KEYInspiration and ribs: do you see at least 8-9 posterior ribs (if too little inspiration, things can crowd and mimic abnormalities)Exposure: can you see the spine through the heart (too much penetra...
