Study Notes
Percussion and Auscultation of the Lungs
- Tympany: a hollow drum-like sound produced when a gas-containing area is tapped sharply, normally heard in the stomach, but if heard in the thorax, may indicate pneumothorax or air in the thorax.
Auscultation of Breath Sounds
- To auscultate, locate the apex on the posterior chest wall or at C7 on the spinal cord and have the patient in a comfortable position, alert for signs of distress.
- Hyper resonance: trapped air, indicating possible emphysema.
- Excursion: equally bilateral, abnormal findings on tone assessment.
Percussion and Palpation
- Percussion helps determine if underlying tissues are filled with air, fluid, or solid material.
- Percussion for tone starts at the apices of the scapula or acromion, remaining symmetric for bilateral position.
- Palpation with unequal fremitus may indicate consolidation in the lungs.
Normal Findings
- Resonance: normal lung tone resonance, indicating normal lung tissue.
- Dullness: fluid or solid tissues replacing the lungs, indicating possible pleural effusion.
Abnormal Findings
- Diminished or absent breath sounds: indicate no air moving in or out of the lungs, possibly due to obstruction, pleural space effusion, or pneumothorax.
- Hyperinflated nature of the lungs: loss of elasticity or decreased function of lung tissue.
- Adventitious sounds: unusual sounds superimposed on normal breath sounds, including fine crackles, indicative of pneumonia.
