Lesson 1Standardized views and sequence: lung zones (anterior/lateral/posterior as feasible), cardiac FoCUS, IVC, focused lower-extremity venous examThis lesson describes a practical, repeatable scan order for breath-short patients in Eritrea, covering front, side, and back lung areas if possible, then targeted heart views, main vein check, and focused leg vein exam to smooth work flow.
