What is a common cause of compression atelectasis?

Compression atelectasis occurs when external pressure causes the alveoli to collapse, leading to reduced lung volume and impaired gas exchange. A common cause of this condition is fluid accumulating in the pleural space, known as pleural effusion, which exerts pressure on the lungs, preventing them from fully expanding.

Fluid overload can result from various conditions, such as congestive heart failure, where excess fluid can lead to pulmonary congestion and increased pressure on the lung tissue. This pressure restricts the expansion of the lungs during inhalation, contributing to the development of atelectasis.

Understanding the mechanism of compression atelectasis is important for recognizing related clinical scenarios and addressing patient needs effectively in respiratory care.
