Evaluation of the aorta from a transcutaneous approach 👇🏻
‘From a parasternal long-axis (PLAX) window, the sinuses and a segment of the ascending aorta are seen.
From the suprasternal notch (SSN) window, the arch and proximal descending thoracic aorta are seen.

🧵 The Lung Point sign is a highly specific ultrasound sign of pneumothorax. It involves visualising the point where the visceral pleura (lung) begins to separate from the parietal pleural (chest wall) at the margin of a pneumothorax

‘Jellyfish sign’ ⇆ solid lung floating within a pleural effusion ⇦ this is called compressive atelectasis
‘Plankton sign’ ⇆ multiple echogenic dots (air bubbles) within pleural effusion suggesting exudate, haemothorax or empyema

Visualization of different lung lobes depends on transducer position. The upper, middle, and lower lung lobes can be visualized as the transducer is moved from the anterior to posterior chest wall.

Lung Point: the point where lung sliding meets no lung sliding. Seen in the pneumothorax. This was the case of a middle-aged woman with a large left pneumothorax. This was drained, but we scanned it prior to repeating CXR to see if it was fully re-expanded. It wasn't, but at
