Atelectasis is the collapse of one part of a lung or the improper inflation of one part of the lung, which causes difficulty in gas exchange.This is usually caused by the closure of alveoli. How … There are several types of atelectasis according to their underlying mechanisms or the distribution of alveolar collapse; resorption, compression, microatelectasis and atelectasis by contraction. This may cause part or all of your lung to collapse. What Are the Symptoms of Pulmonary Lung Disease?

Atelectasis; is the situation in which a part of the whole of the lung goes out and loses the air inside and closes. Especially before long-term surgical procedures, the content of the air in the lung changes due to the gaseous anesthetic substances are taken by inhalation, causing the lungs to shrink. Without this elasticity, it becomes difficult to exhale. Atelectasis is caused due to the obstruction in the airway or pressure on the air sacs from the outside. Atelectasis is another word for lung collapse. The commonest cause is a bronchial obstruction that results in distal gas resorption and a reduction in the volume of gas in the affected lung, lobe, segment or subsegment. Another common cause is What are the Causes of Atelectasis? Atelectasis can also happen when a tumor, excess mucus, or a piece of food blocks an airway, or because of a pneumothorax or pleural effusion. There are some patients who experience Atelectasis because of anaesthesia administered to them during surgery. Congenital atelectasis is due to incomplete expansion of the lungs, including primary and secondary congenital atelectasis, whereas the most common causes of later atelectasis are loss of air in lung tissue previously expanded or collapse of a lung or lung tissue. Surfactant, a substance produced by the lung to reduce surface tension, is lacking. What causes discoid atelectasis?

Atelectasis results as a build-up of fluid between the pleura and the inside of the chest wall cause a complete or partial collapse of the lung. It is known as Atelectasis. Air distal to the blockage causes collapse and atelectasis of the lung. It is seen that general anesthesia is a common cause of the condition, which changes the breathing patterns and affects the exchange of lung gases, thereby leading to the deflation of the alveoli. Lung Atelectasis also referred to as Atelectasis lung, occurs when a lung or its lobe partly or fully gives away (collapses) as a result of the shrinkage of the alveoli, which are the tiny air sacs, inside the lung.
