- Atelectasis (from Greek: ἀτελής, incomplete + ἔκτασις, extension) is defined as the collapse or closure of the lung resulting in reduced or absent gas exchange.

- Atelectasis may have few or no symptoms if it develops slowly or involves only a small portion of the lungs. Conversely, if the condition affects a large portion of the lungs, or develops rapidly, symptoms may be dramatic and may even progress to shock.

Causes and Treatment of Atelectasis Atelectasis is a medical term used to describe the complete or partial collapse of a lung. It is sometimes referred to as a collapsed lung, although the term can also be applied to a condition called pneumothorax. When atelectasis occurs, fresh air is unable to reach the tiny structures of lungs, called the alveoli, where oxygen and carbon dioxide are exchanged.

What Is Compressive Atelectasis? Compressive atelectasis is a medical condition where a patient's lung cannot fully inflate, limiting the volume of air the patient can inhale with a given breath. This condition can have a number of causes, and it requires medical treatment to address the dysfunction in the lung and help the patient breathe. Patients with untreated compressive atelectasis can be at risk of complications associated with low oxygenation, like organ damage.

Lung Disease Induced Atelectasis Ventilators can heavily contribute to the onset of atelectasis. Typically, breathing is shallow during the use of a ventilator. This causes a lack of use of the alveoli near the bottom and the back of the lungs, which can induce atelectasis. The other major cause of atelectasis is blockage of airways. This can happen from mucus build-up or other lung disease symptoms, the presence of a foreign object in the airway, or an abnormal growth.

- Partial lung collapse. Atelectasis is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the outside of the lung. It is common after surgery, or in patients who were in the hospital. Risk factors for developing atelectasis include: Anesthesia.

- 1 External pressure: Atelectasis caused by external pressure from a tumor or fluid is addressed by removing the tumor, or suctioning/draining the fluid.  Blockage: A physical obstruction of the airway can be removed surgically or via bronchoscopy. A mucus plug is loosened using medication or chest percussions.

Top 30 Doctor insights on: What Is Bibasal Atelectasis In brief: Ligula. The ligula is the equivalent of the middle lobe of the lung on the left-hand side. There is no true middle lobe but it is an area of the left lung. Atelectasis refers to an area of the lung where there is no good gas exchange due to either obstruction or filling in with fluid. This is often seen with an infection.

atelectasis Atelectasis can result from an obstruction (blockage) of the airways that affects tiny air scas called alveoli. Alveoli are very thin-walled and contain a rich blood supply. They are important for lung function, since their purpose is the exchange of oxygen and carbon dioxide.

Atelectasis Atelectasis is defined as diminished volume affecting all or part of a lung. Pulmonary atelectasis is one of the most commonly encountered abnormalities in chest radiographs. Recognizing an abnormality due to atelectasis on chest radiographs can be crucial to understanding the underlying pathology.

The Skinny on... Chicken The best remedy is to brine the cuts before cooking. Mix 3 tablespoons salt, preferably kosher salt, with 4 cups (1 quart) cool water in a large bowl. Add the boneless skinless chicken breasts, submerging them in the brine. Refrigerate for 30 minutes or up to 1 hour. The meat will plump considerably and can hardly be overcooked.

Overview Definition. Atelectasis (at-uh-LEK-tuh-sis) — a complete or partial collapse of a lung or lobe of a lung — develops when the tiny air sacs (alveoli) within the lung become deflated.It's a breathing (respiratory) complication after surgery.Atelectasis is also a possible complication of other respiratory problems, including cystic fibrosis, inhaled foreign objects, lung tumors, fluid in the lung, respiratory weakness and chest injuries.The amount of lung tissue involved in atelectasis is variable, depending on the cause.efinition.
