    INPUT: Endotracheal tube tip terminates at the orifice of the right mainstem bronchus , and should be retracted by approximately 4 cm .

Infection or aspiration can not be excluded . The heart size is mildly enlarged . Crowding of the bronchovascular structures may be attributable to low lung volumes , though mild pulmonary vascular congestion is also likely present . Streaky right basilar atelectasis is also demonstrated . No pleural effusion or pneumothorax is apparent . Multiple remote left - sided healed rib fractures are visualized .
