This retrospective study looked at chest X-ray findings to see if there was a similar size cut-off where patients could be safely observed rather than undergo this invasive procedure. They found 38mm was the size over which observation failed. Of note, lactic acidosis and need for supplemental oxygen also predicted the need for chest tube placement </p>
