What causes atelectasis in the lungs?
Atelectasis is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the outside of the lung. Atelectasis is not the same as another type of collapsed lung called pneumothorax, which occurs when air escapes from the lung.
Is atelectasis serious?
Large-scale atelectasis may be life threatening, especially in someone who has another lung disease or illness. In a baby or small child, lung collapse due to a mucus obstruction or other causes can be life threatening.
Is atelectasis the same as pneumonia?
Atelectasis is collapse of lung tissue with loss of volume. Patients may have dyspnea or respiratory failure if atelectasis is extensive. They may also develop pneumonia. Atelectasis is usually asymptomatic, but hypoxemia and pleuritic chest pain may be present in certain cases.
Can atelectasis be reversed?
Atelectasis is when the airways or air sacs in the lungs collapse or do not fully expand. Atelectasis is usually reversible. However, without medical care, it can lead to potentially fatal complications.
How do you get atelectasis?
Atelectasis occurs from a blocked airway (obstructive) or pressure from outside the lung (nonobstructive). General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.
What does atelectasis mean on a CT scan?
Atelectasis refers to either incomplete expansion of the lungs or the collapse of previously inflated lungs, which produces areas of relatively airless pulmonary parenchyma.
What are 3 causes of atelectasis?
Possible causes of nonobstructive atelectasis include:
- Injury. Chest trauma — from a fall or car accident, for example — can cause you to avoid taking deep breaths (due to the pain), which can result in compression of your lungs.
- Pleural effusion.
- Pneumonia.
- Pneumothorax.
- Scarring of lung tissue.
- Tumor.
