Detailed explanation-1: -Atelectasis (at-uh-LEK-tuh-sis) is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid.

Detailed explanation-2: -A collapsed lung occurs when air escapes from the lung. The air then fills the space outside of the lung between the lung and chest wall. This buildup of air puts pressure on the lung, so it cannot expand as much as it normally does when you take a breath. The medical name of this condition is pneumothorax.

Detailed explanation-3: -The two main types of atelectasis are obstructive (also called resorptive) and nonobstructive. Obstructive atelectasis happens when something physically blocks your airway. Types of nonobstructive atelectasis include: Relaxation or compressive.

Detailed explanation-4: -Atelectasis, the collapse of part or all of a lung, is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the lung. Risk factors for atelectasis include anesthesia, prolonged bed rest with few changes in position, shallow breathing and underlying lung disease.

Detailed explanation-5: -There are three main types of atelectasis: compressive, resorptive (obstructive) and contraction.
