Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Dobhoff type tube with radiopaque tip overlying the gastric fundus . Left subclavian central line with tip over mid / distal SVC . There are low inspiratory volumes . Cardiomediastinal silhouette is probably unchanged . Mild vascular plethora is suggested , similar to the prior film . However , this appearance is likely accentuated due to low inspiratory volumes . Minimal patchy opacity at both lung bases again noted , similar to the prior film . No frank consolidation , effusion , or pneumothorax detected .
    OUTPUT:
    
Allowing for lower inspiratory volumes , doubt significant interval change .
