    INPUT: The endotracheal tube tip is 6 .8 cm above the carina . The right IJ central catheter terminates in the lower SVC . No pneumothorax . No significant change in the vascular engorgement and bilateral interstitial pulmonary edema , worse on the left . It is difficult to decipher how much of this is due to chronic interstitial disease . Cardiac silhouette is unchanged , as is the right pacer / defibrillator with leads in the right atrium and right ventricle . Left subclavian and left IJ stents are also unchanged .
    OUTPUT:
    
1 . Interval placement of an ET tube , which terminates 6 .8 cm above the carina . 2 . No change in the left greater than right interstitial pulmonary edema .
