Lung sliding

Pleurae .5cm below the ribs
Hyperechoic (very bright) and move with respiration
Visceral and parietal pleurae “slide” against each other with respiration
Presence of lung sliding strongly rules out pneumothorax at that rib space
Lack of lung sliding suggests pathology
Pneumothorax will push the visceral pleura off the parietal pleura
Right main-stem intubation abolishes left lung sliding
