    INPUT: The endotracheal tube tip terminates 5 .5 cm above the level of the carina . Diffuse bilateral alveolar opacities are new from prior and likely reflect moderately severe pulmonary edema given the clinical history of heart failure . Additionally , baseline cardiomegaly has increased , findings consistent with decompensated heart failure . There are possible small layering bilateral pleural effusions . No pneumothorax is identified . A linear opacity in the medial right lung base is unchanged from multiple priors and may reflect a foreign body .
    OUTPUT:
    
1 . Endotracheal tube 5 .5 cm above the carina in standard position . 2 . New moderately severe pulmonary edema . 3 . Increased cardiomegaly , now moderately severe . 4 . Stable foreign body ( uncertain etiology ) overlying the right medial lung base .
