Template:Lung ultrasound pneumothorax

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
