Atelectasis is a collapse of the air sacs in the lungs called alveoli. It may occur in a portion of the lung, or in the entire lung. Normally, oxygen enters the body through the lungs and is exchanged with carbon dioxide in the alveoli. The lungs expand and contract to create the exchange of these gases.
Atelectasis is not a disease, but a condition or sign that results from disease or abnormalities in the lungs.
Treatment focuses on treating the underlying cause and maintaining enough oxygen. The collapsed lung usually expands after the underlying cause has been corrected. Mild atelectasis often goes away on its own without treatment.
The therapist uses different techniques to help clear mucus from the lung. You will be positioned so that gravity helps secretions flow out of the body. When resting in bed, lie on the unaffected side to promote drainage from the lung area that has collapsed. Moving around will also help clear your lungs.
Respiratory therapy may include any or all of the following:
Breathing masks or treatments to help keep your airways open
Incentive spirometry to promote deep breathing
Suction to help remove secretions
Mechanical ventilation if you are unable to breathe adequately on your own
