what to inspect on respiratory assessment
shape/symmetry of chest (barrel chest), breathing rate, depth of respirations, effort of breathing, oxygen supply(room air)
what do you palpate on respiratory assessment
chest excursion, vocal/tactile fremitus, lumps, massess, tenderness
how to assess chest excursion
posterior, hands spread thumbs touching, have take deep breath and thumbs should separate
