Question: 1 / 400

What does a prolonged exhalation typically imply?

Normal respiratory function

Expiratory obstruction

A prolonged exhalation typically implies expiratory obstruction, which occurs when there is difficulty or resistance in expelling air from the lungs. This condition can result from various factors such as airway blockages due to conditions like asthma, chronic obstructive pulmonary disease (COPD), or other pulmonary issues. In normal respiratory function, the exhalation phase would be more balanced with inhalation, indicating smooth airflow.

When exhalation is prolonged, it can suggest that the airways are narrowed or obstructed, leading to an increased time needed to expel air fully. This is particularly relevant in the context of respiratory assessments, as healthcare professionals often look for signs of such obstructions to diagnose underlying issues accurately.
