Predominant A lines +<unk> sliding = Asthma/COPD
Multiple predominant B lines anteriorly with<unk> sliding = Pulmonary Edema
Normal anterior profile + DVT= PE
Anterior absent<unk> sliding + A lines +<unk> point = Pneumothorax (PTX)
Anterior alveolar consolidations, anterior diffuse B lines with abolished<unk> sliding, anterior asymmetric interstitial patterns, posterior consolidations or effusions with out anterior diffuse B lines = Pneumonia
No<unk> sliding seen (not specific for pneumothorax)
May also identify "lung point": distinct point where you no longer see<unk> sliding (pathognomonic)
Absence of<unk> sliding WITHOUT<unk> point could represent apnea or right mainstem intubation
Evaluate other intercostal spaces because pneumothorax may only be seen in least dependent area of thorax
NO comet tail artifact
Bar Code appearance/"Stratosphere" sign on M-mode (absence of "seashore" waves)
Ultrasound has greater sensitivity than chest x-ray for pneumothorax in trauma patients

A lines and B lines
A lines:
Appear as horizontal lines
Indicate dry interlobular septa.
Predominance of A lines has 90% sensitivity, 67% specificity for pulmonary artery wedge pressure <= 13mm Hg
A line predominance suggests that intravenous fluids may be safely given without concern for pulmonary edema
B lines ("comets"):
White lines from the pleura to the bottom of the screen
Highly sensitive for pulmonary edema, but can be present at low wedge pressures
A lines:
Appear as horizontal lines
Indicate dry interlobular septa.
