Subcutaneous Emphysema on POCUS Air, air everywhere...but not a lung in sight?! 18M hit in neck with tire iron. Subcutaneous air tracking around the carotid. Lots of air tracking in the deep tissue planes, with posterior dirty shadowing. Always good to correlate with history and physical exam. - VCU Ultrasound @ultrasound_vcu #Subcutaneous #Emphysema #POCUS #carotid #ultarsound #clinical #neck #air
