    INPUT: Since the prior exam , the endotracheal tube has been removed . A new tracheostomy tube sits 7 .5 cm from the carina . An enteric tube and right PICC are unchanged . The opacity at the right base appears slightly improved since the prior exam , while an opacity at the left base appears worse . These changes may be due to patient rotation . Small bilateral pleural effusions are not significantly changed . There is no pulmonary edema or pneumothorax . The cardiomediastinal silhouette is poorly evaluated due to patient rotation .
    OUTPUT:
