3. Lung Ultrasound Protocol

Step 2: Lung ultrasound of lateral chest (L2/ R2)

Point 2 (R2 and L2) examines the lateral chest.

  • Place your probe at the right (R2) or left (L2) Midaxillary line around the 6-7th intercostal space. This should be just lateral to the nipple line in males.
  • Anchor your probe between two ribs, and just like in point 1, look for the batwing sign, lung sliding, and A-lines.
