Hyperresonance

Definition

Hyperresonance is an abnormal increase in the resonance of lung sounds, often indicating trapped air in the lungs. It is detected through percussion during a physical examination.

5 Must Know Facts For Your Next Test

1. Hyperresonance can be a sign of conditions like emphysema or pneumothorax.
2. It is identified by a hollow, drum-like sound when tapping on the chest.
3. Hyperresonance suggests increased air volume and decreased lung tissue density.
4. Nutritional deficiencies, such as protein-energy malnutrition, can exacerbate pulmonary conditions leading to hyperresonance.
5. A thorough nutritional assessment may help manage and prevent conditions associated with hyperresonance.
