Lung ultrasound of pneumothorax
- No lung sliding seen (not specific for pneumothorax)
- May also identify "lung point": distinct point where you no longer see lung sliding (pathognomonic)
- Absence of lung sliding WITHOUT lung 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 [1]
