What is cupola sign?

The cupola sign is a medical term used to describe a specific physical finding that can often be observed during a respiratory exam. It refers to the observation of a dome-like bulge or protrusion in the upper part of the chest. This bulge typically appears in patients who are experiencing respiratory distress and is caused by the elevation of the diaphragm.

The cupola sign can be indicative of a number of different respiratory conditions, including chronic obstructive pulmonary disease (COPD), asthma, pneumonia, and others. It is typically observed during a physical exam, but may also be seen on a chest X-ray or CT scan.

When assessing a patient with the cupola sign, healthcare providers will look for other symptoms and perform additional tests to help determine the underlying cause of the respiratory distress. Treatment for the condition will depend on the specific diagnosis and may include medications, oxygen therapy, or other interventions.
