A pulmonary consolidation is a region of (normally compressible) lung tissue that has filled with liquid,〔(【引用サイトリンク】title=Consolidation – Definition )〕 a condition marked by induration〔(【引用サイトリンク】title=Induration- Definition )〕 (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign. Consolidation occurs through accumulation of inflammatory cellular exudate in the alveoli and adjoining ducts. Simply, it is defined as alveolar space that contains liquid instead of gas. The liquid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or hemorrhage from a pulmonary artery). It must be present to diagnose pneumonia: the signs of lobar pneumonia are characteristic and clinically referred to as consolidation.〔 ==Signs== Signs that consolidation may have occurred include: *Expansion of the thorax on inspiration is reduced on the affected side *Vocal fremitus is increased on the side with consolidation *Percussion is dull in affected area *Breath sounds are bronchial *Possible medium, late, or pan-inspiratory crackles *Vocal resonance is increased. Here, the patient's voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to in the healthy lung where speech sounds muffled. *A pleural rub may be present.〔 *A lower expected Pa02 than calculated in the alveolar gas equation 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pulmonary consolidation」の詳細全文を読む スポンサード リンク
