Lung sounds & tactile fremitus explanation
Consolidation = Inside your lungs
Effusion = Outside your lungs
Effusions create MORE SPACE between ur lung tissue & body wall, while consolidations do not. Fremitus is felt due to vibrations from sound transmission thru lung tissue, which are better conducted (Solid > Liquid > Gas).
Therefore:
CONSOLIDATION: lungs still close to wall with more tissue inside them -> more vibration -> increased fremitus
EFFUSION: lungs farther from wall -> Fluid dissipates vibrations -> decreased fremitus
