Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in sitting semi-upright position . Comparison is made with the next preceding similar study of ___ . During the interval , the patient has been extubated . No pneumothorax has developed . Rather high - positioned diaphragms indicate poor inspirational effort and this conceals some major portion of the cardiac silhouette . However , there is no suspicion for significant cardiac enlargement as the pulmonary vasculature is not congested . No new acute infiltrates can be identified . The lateral pleural sinuses remain free . Skeletal structures of the imaged thorax are grossly unremarkable . If suspicion for specific skeletal injuries exists it is recommended to request dedicated rib examination , thoracic spine or shoulders etc .
    OUTPUT:
    
Extubated , no pneumothorax or new parenchymal infiltrates . Skeletal structures grossly unremarkable .
