What is a common respiratory finding in individuals with emphysema?

Increased lung compliance is a common respiratory finding in individuals with emphysema. This condition, characterized by the destruction of alveolar walls, leads to a loss of elasticity in the lung tissue. As a result, the lungs become more compliant, meaning they can expand more easily during inhalation. However, this increased compliance comes at a cost; while inspiration may become less effortful, the ability to effectively exhale is compromised. This phenomenon leads to air trapping and hyperinflation, which contributes to the classic symptoms and physical examination findings associated with emphysema, such as reduced breath sounds and a prolonged expiratory phase.

Other options may relate to different conditions or concepts that are not typical findings in emphysema. For example, hypocapnia involves decreased levels of carbon dioxide in the blood and is more associated with hyperventilation or certain acute conditions. Consolidation typically refers to conditions like pneumonia where lung tissue becomes denser, and decreased resonance upon percussion is often related to fluid accumulation or solid masses in the lung, neither of which align with the typical findings in emphysema.
