Detecting possible atelectasis and other respiratory problems that may develop immediately after extubation via lung ultrasonography can reduce pulmonary complications by performing necessary interventions such as oxygen support, respiratory exercises, mobilization, and non-invasive mechanical ventilation applications at an early stage. In addition, although low-flow anesthesia is frequently used in daily anesthesia practice, publications showing the effects of its use in laparoscopic cholecystectomy operations on pulmonary complications are limited. On this occasion, this study can be presented as a contribution to the literature.
