    INPUT: The endotracheal tube in the low trachea approximately 2 cm from the carina . A nasogastric tube can be traced to the mid chest , but can not be traced further . The lung volumes are low . There is vascular engorgement and diffuse bilateral interstitial opacities , most consistent with moderate pulmonary edema . There is no definite pleural effusion . There is no pneumothorax . The mediastinal contour is widened , which may be due to technique , although acute aortic dissection is a consideration . The heart size is mildly enlarged .
    OUTPUT:
    
1 . Moderate pulmonary edema and mild cardiomegaly . 2 . Widened mediastinum , which may be due to technique , although acute aortic dissection is a consideration . 3 . Satisfactory position of the endotracheal tube . 4 . The nasogastric tube can not be traced below the mid chest , due to technical limitations . If imaging confirmation is required , consider a repeat chest radiograph . Results were discussed with Dr . ___ at 8 :50 AM on ___ via telephone by Dr . ___ .
