Lesson 1Standardised views and sequence: lung zones (anterior/lateral/posterior as feasible), cardiac FoCUS, IVC, focused lower-extremity venous examDescribes a practical, repeatable scanning order for dyspnoeic patients, including anterior, lateral, and posterior lung zones where possible, then focused cardiac views, IVC check, and targeted lower limb venous exam to smooth workflow.
