It is common during asbestosis-a lung disease caused by the inhalation of asbestos particles. This unusual type of bibasilar atelectasis happens when the lung is trapped as a result of pleural disease while being devoid of air. Round atelectasis: Round atelectasis is also called Blesovsky syndrome, or folded lung. In a pulmonary embolism, the surfactant is impaired due to a lack of carbon dioxide and blood flow loss. However, the alveoli will collapse and become atelectatic when there is a surfactant deficiency. The negative pressure loss in the pleura makes the lung relax because of the elastic shrinking.Īdhesive atelelctasis: A surfactant, a liquid that covers the inside of the lungs, reduces tension and keeps the alveoli open. It is common in pleural effusion and pneumothorax patients.

The lung shrinks and becomes atelectatic due to its elastic properties. Relaxation atelectasis: This type occurs once negative pressure is lost in the pleural cavity, the thin, fluid-filled space between the lungs and the chest wall. Although blood flow continues, atelectasis results as oxygen and nitrogen gradually get absorbed. Resorptive (obstructive) atelectasis: A type of lung collapse caused by obstructed airways. There are multiple types of atelectasis, which correspond to the biological mechanisms that lead to the state of collapse. The word atelectasis comes from the Greek terms ateles and ektasis, which mean “incomplete” and “expansion,” respectively. Pneumothorax can lead to bibasilar atelectasis. The life-threatening result occurs from a lack of oxygen reaching vital organs of the body.Īlthough it is similar to pneumothorax, bibasilar atelectasis is caused by different conditions and situations. It affects the bottom portions of the lungs. These are called alveoli, which abnormally deflate due to an obstruction of the airflow with bibasilar atelectasis. There are tiny air sacs shaped like balloons containing blood vessels arranged in clusters throughout the lungs. The left lung has two lobes, and the right lung has three lobes. We have two lungs-the left and the right-both containing lobes. In medical terms, bibasilar atelectasis definition refers to a partial or complete collapse of a lung or both lungs. Daniel on what does crackles in lungs mean: is a very generic nonspecific means that there is something in the lung on xray or CT that could be almost anything, form normal to abnormal, from innocuous to serious.
