Atelectasis is a condition where a lung, or part of a lung, collapses. This happens when the tiny air sacs in your lungs (alveoli) deflate and don't inflate properly.
Here's a breakdown:
* What: A collapsed or partially collapsed lung.
* How: The air sacs in the lungs (alveoli) don't inflate properly due to various reasons.
* Types:
* Resorption atelectasis: The most common type, caused by blockage of an airway (like mucus or a tumor).
* Compression atelectasis: Happens when pressure from outside the lung squeezes the air out (like from a tumor or fluid buildup).
* Contraction atelectasis: Occurs due to scarring in the lung tissue.
* Symptoms: Often asymptomatic, but can cause:
* Shortness of breath
* Coughing
* Chest pain
* Wheezing
* Rapid heartbeat
* Fever
* Causes:
* Respiratory infections: Pneumonia, bronchitis, etc.
* Surgery: Post-operative pain can limit deep breaths and cause atelectasis.
* Mucus: Thick mucus blocks airways.
* Tumors: Can block airways or press on the lung.
* Foreign objects: Can obstruct airways.
* Breathing problems: Chronic obstructive pulmonary disease (COPD), asthma.
* Fluid buildup: Pleural effusion, pneumothorax.
* General anesthesia: Can cause temporary atelectasis.
* Diagnosis: Chest X-ray, CT scan, or pulmonary function tests.
* Treatment: Depends on the cause, but can include:
* Deep breathing exercises: To clear airways and expand the lungs.
* Coughing: To clear airways.
* Oxygen therapy: To improve oxygen levels.
* Antibiotics: To treat infections.
* Bronchodilators: To open airways.
* Chest physiotherapy: To loosen mucus and help clear airways.
* Surgery: To remove blockages or repair lung damage.
It's important to note that atelectasis can be a serious condition, and prompt medical attention is essential.
