As the lowest lobes of the lungs get collapsed, the alveoli situated in these lobes could no longer exchange the gases from the blood. Atelectasis does not preferentially affect either sex.

This prevents air from getting to your alveoli, and as a result they collapse. This is due to the fact that anesthesia changes the normal pattern of breathing and absorption of gases, which can cause the collapse of some of the tiny air sacs in the lung. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. This appearance can be confused with a large pleural effusion, but the mediastinal shift towards a collapsed lung can distinguish it from pleural effusion where the shift is in the opposite direction of the pathology.

The term atelectasis can also be used to describe the collapse of a previously inflated lung, either partially or fully, because of specific respiratory disorders.

Source images were transmitted to workstations for multiplanar reconstructions and to picture archiving and communication systems (PACS). Some of the causes of atelectasis are quite serious and need to be addressed by medical professionals immediately.

For the analysis of qualitative variables, after checking if the collected variable met the minimum characteristics required, a 2 test was done. Patients with larger atelectasis requires more intensive surveillance and might benefit of open lung techniques. It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.It is often called a collapsed lung, although that term may also refer to pneumothorax.

The air then fills the space outside of the lung, between the lung and chest wall. when there is a question in diagnosing the patient. The mild bibasilar atelectasis, even after treatment may reduce the overall capacity of the lungs. The Sat O2/FiO2 ratio and atelectasis detection by chest CT might be two valuable tools for the lung function assessment of these patients and hence might be helpful to predict those patients who will need mechanical ventilation, ICU admission and prolonged length of in-hospital stay.
