Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A tracheostomy is in - situ . A right - sided subclavian Port - A - Cath is unchanged in position , the tip is in the mid SVC . A left - sided internal jugular catheter terminates in the proximal SVC . A nasogastric tube is incompletely visualized but terminates below the diaphragm . A right - sided pleural drain is unchanged in position . A right upper quadrant pain is also unchanged . There has been interval development of very extensive bilateral airspace opacities . This involves nearly all the lung but has some peripheral sparing . The appearances are most consistent with acute pulmonary edema , particular given the rapid interval progression . Infection is considered less likely .
    OUTPUT:
    
New extensive bilateral and relatively symmetric airspace opacities most consistent with acute pulmonary edema . Infection is considered less likely .
