II. Definitions
- Atelectasis
- Alveolar collapse of lung lobe or segment
III. Pathophysiology
-
Bronchial obstruction results in Lobar Collapse
- Implies lack of collateral ventilation
- Air distal to obstruction reabsorbed in 4-24 hours
- Reabsorption is faster with Supplemental Oxygen
IV. Causes
- Focal Splinting of respiratory Muscle and chest wall movement (limited by pain)
- Post-operative change
- Rib Fracture or rib Contusion
- Airway obstruction
- Mucus plugging
- Foreign Body Aspiration
- Lung Mass
V. Symptoms
VI. Signs
-
Fever is not caused by atelectesis
- Both atelectesis and fever are a result of the same triggers (e.g. major surgery)
- Affected lung side or lobe
- Diminished respiratory movements
- Diminished breath sounds
- Dullness to percussion
- Tracheal displacement toward affected side
VII. Labs
VIII. Imaging
- See Atelectasis on Chest XRay
-
Chest XRay
- Lung opacity in affected area
- Shifted mediastinum to affected side
- Elevated diaphragm on affected side
-
Chest CT
- Definitive imaging of obstructive lesions
IX. Management
- Incentive Spirometry
- Relieve obstruction (e.g. Lung Mass, Foreign Body Aspiration, mucus plugging)
-
Analgesics or Regional Anesthesia if Splinting due to pain
- See Rib Fracture

| Definition (MSH) | Absence of air in the entire or part of a lung, such as an incompletely inflated neonate lung or a collapsed adult lung. Pulmonary atelectasis can be caused by airway obstruction, lung compression, fibrotic contraction, or other factors. |
| Definition (MSHCZE) | Nepřítomnost vzduchu v celých plicích nebo jejich části např. u nedovyvinutých plic novorozence nebo při plicním kolapsu dospělých. Plicní atelektáza může být způsobená vzduchovou obstrukcí, plicní kompresí, fibrózním zmnožením tkáně (kolapsová plicní indurace) nebo z jiné příčiny. |
| Definition (MEDLINEPLUS) |
A collapsed lung happens when air enters the pleural space, the area between the lung and the chest wall. If it is a total collapse, it is called pneumothorax. If only part of the lung is affected, it is called atelectasis. Causes of a collapsed lung include
If only a small area of the lung is affected, you may not have symptoms. If a large area is affected, you may feel short of breath and have a rapid heart rate. A chest x-ray can tell if you have it. Treatment depends on the underlying cause. NIH: National Heart, Lung, and Blood Institute |
| Definition (NCI_CTCAE) | A disorder characterized by the collapse of part or the entire lung. |
| Definition (NCI) | The collapse of part or the entire lung due to airway obstruction, infection, tumor, or general anesthesia. |
| Definition (NCI_NCI-GLOSS) | Failure of the lung to expand (inflate) completely. This may be caused by a blocked airway, a tumor, general anesthesia, pneumonia or other lung infections, lung disease, or long-term bedrest with shallow breathing. Sometimes called a collapsed lung. |
| Definition (CSP) | collapse of all or part of a lung due to bronchial plugging or the chest cavity being opened to atomspheric pressure. |
