Lung Biopsy:
As with pleural biopsy,  lung biopsy may  be  done by  surgical exposure of the lung (open lung biopsy) with or without endoscopy using a needle designed to remove a core of lung tissui. Tissue is then examined for abnormal cellular structure and bacteria. Lung biopsies are most often done to  identify pulmonary tumors or parenchymal changes (e.g.  sarcoidosis). 

Postprocedure  Care
After the procedure, examine any sputum closely for evidence of blood. Observe for respiratory distress (may indicate pneumothorax). Monitor the clients vital signs, breath sounds, skin colour, and temperature.
