Overview
Physical findings for effusions are determined by the volume of pleural fluid and the extent of lung compression. Pleural fluid also interferes with transmission of low-frequency vibrations and results in diminished tactile fremitus, asymmetric chest expansion, decreased or absent fremitus posteriorly and laterally, dullness on percussion, decreased or absent breath sounds, and reduced vocal resonance.[1]
Physical Examination
Physical signs for pleural effusions were first recognized by Josef Leopold Auenbrugger, who described dullness to percussion and diminished expansion of the chest wall,[2] and René-Théophile-Hyacinthe Laennec, who described the abnormal vocal resonance and bronchial breath sounds in patients with effusions.[3] Excessive accumulation of fluid in the pleural cavity expands the hemithorax and collapses the involved lungs, which produces asymmetric chest expansion with reduced breath sounds. Pleural fluid also interferes with transmission of low-frequency vibrations and results in diminished tactile fremitus. Asymmetric chest expansion, diminished fremitus, dullness on percussion, decreased or absent breath sounds, and reduced vocal resonance were reported to have a sensitivity and specificity of 74% and 91%, 82% and 86%, 89% and 81%, 88% and 83%, and 76% and 88%, respectively.[1]
Physical Findings Based on Pleural Fluid Volume[4][5]
| Pleural fluid volume | Physical findings |
| 250 to 300 ml | May be unremarkable |
| 500 ml | Decreased intensity of breath sounds Dullness to percussion Decreased fremitus |
| 1000 ml | Absence of inspiratory retraction Mild bulging of the intercostal spaces Decreased chest expansion Bronchovesicular breath sounds of decreased intensity Egophony Dullness to percussion up to the level of the scapula and axilla Decreased or absent fremitus posteriorly and laterally |
| When fluid fills the entire hemithorax | No expansion of the chest wall Bulging of the intercostal spaces Minimal bronchovesicular breath sounds Egophony Dullness to percussion over the entire hemithorax A palpable liver or spleen due to diaphragmatic depression |
