    INPUT: ET tube tip is approximately 4 .5 cm above the carina . Heart size is normal . The pulmonary vasculature is normal . Allowing for differences in patient positioning , the right apical cavitary process with previously seen air - fluid level is probably not significantly changed , as the size of the cavitation appears similar . The air - fluid level is probably no longer seen due to the patient being supine . No pneumothorax .
    OUTPUT:
    
ET tube tip is approximately 4 .5 cm above the carina .
