Atelectasis

Overview

The lungs are composed of millions of tiny air sacs called alveoli, which are responsible for the exchange of oxygen and carbon dioxide during breathing. In atelectasis, these air sacs lose their air and collapse, preventing proper gas exchange. The term "atelectasis" comes from the Greek words "ateles" meaning incomplete and "ektasis" meaning expansion.

Atelectasis can be classified based on the underlying mechanism: obstructive (resorption) atelectasis occurs when airways are blocked, preventing air from reaching the alveoli; non-obstructive atelectasis results from external pressure on the lung, loss of surfactant, or other factors that cause alveolar collapse without airway obstruction.

The condition can affect people of all ages but is particularly common in certain populations. Post-operative patients, especially those undergoing abdominal or thoracic surgery, have a high risk of developing atelectasis. Additionally, individuals with chronic lung diseases, those on prolonged bed rest, and patients requiring mechanical ventilation are at increased risk.

While atelectasis can be a minor, temporary condition that resolves quickly with appropriate treatment, it can also be life-threatening if it involves large portions of the lung or occurs in patients with already compromised respiratory function. Understanding the causes, recognizing symptoms early, and implementing appropriate treatment strategies are essential for preventing complications and ensuring optimal recovery.

Symptoms

The symptoms of atelectasis can vary significantly depending on the extent of lung collapse, the underlying cause, and the patient's overall health status. Small areas of atelectasis may cause no symptoms, while extensive collapse can result in severe respiratory distress.
