Treatment of atelectasis depends on the cause. Mild atelectasis may go away without treatment. Sometimes, medications are used to loosen and thin mucus. If the condition is due to a blockage, surgery or other treatments may be needed.

Is atelectasis reversible?

Atelectasis is reversible collapse of lung tissue with loss of volume; common causes include intrinsic or extrinsic airway compression, hypoventilation, and a malpositioned endotracheal tube.

Is atelectasis acute or chronic?

Atelectasis may be an acute or chronic condition. In acute atelectasis, the lung has recently collapsed and is primarily notable only for airlessness.
