Atelectasis vs. Emphysema — What's the Difference?

By Tayyaba Rehman — Updated on December 30, 2023
Atelectasis is the collapse of part or all of a lung, while emphysema involves the damage and enlargement of air sacs in the lungs, leading to breathlessness.

Difference Between Atelectasis and Emphysema

Key Differences

Atelectasis is a condition where part or the entire lung collapses due to blocked air passages or pressure on the outside of the lung. Emphysema, on the other hand, is a chronic lung condition where the alveoli (air sacs) in the lungs are damaged, leading to difficulty breathing.

In atelectasis, the main issue is the lack of air in the lung's alveoli, causing parts of the lung to deflate. Emphysema, however, is characterized by the overinflation of the alveoli, which eventually lose their shape and become less efficient in oxygen exchange.

The causes of atelectasis include respiratory blockages, such as mucus plugs, or pressure from a tumor or fluid. Emphysema is primarily caused by long-term exposure to irritants, particularly cigarette smoke.

Symptoms of atelectasis often include difficulty breathing, cough, and sometimes chest pain. Emphysema symptoms typically include shortness of breath, wheezing, and a chronic cough.

Treatment for atelectasis involves addressing the underlying cause and may include physical therapy to reopen collapsed lung tissue. Emphysema treatment focuses on managing symptoms and slowing disease progression, often involving inhalers and lifestyle changes.
