From: Anatomical locations of air for rapid diagnosis of pneumothorax in blunt trauma patients
The percentage of air pockets in each hemithorax (right hemithorax 41 patients and left hemithorax 35 patients) according to a grid pattern dividing each hemithorax into six anatomical locations. CL, clavicular line; MC, midclavicular line; MA, midaxillary line; MS, midsternal line; 3rd, 3rd costosternal junction level; 6th, 6th costosternal junction level; UPS, upper parasternal; UL, upper lateral; MPS, middle parasternal; ML, middle lateral; LPS, lower parasternal; LL, lower lateral
