    INPUT: Single portable radiograph of the chest demonstrates a right chest tube with the side port overlying the right lung parenchyma . There has been interval improvement in the right - sided pneumothorax with only a small residual pneumothorax present . The lung volumes remain low , accentuating the cardiac contour and pulmonary vasculature . Small bilateral pleural effusions are seen . Right basilar atelectasis is again noted . Minimal subcutaneous emphysema at the right chest wall is likely due to insertion of the chest tube .
    OUTPUT:
    
Appropriate position of right - sided chest tube with interval improvement in right apical pneumothorax .
