Does higher fraction of inspired oxygen in anesthesia induction affect functional residual capacity reduction after intubation : a comparative study of higher and lower oxygen concentration?
FRC significantly decreased from the awake state to surgery in both groups. FRC was not influenced by FIO2 elevation at anesthesia induction.
Thus, we conclude that visceral fat area is positively associated with the prevalence of CRC. Although we could not determine the causality, visceral adiposity may be associated with the risk of CRC. Further prospective studies are required to determine the benefits of controlling visceral obesity for reducing CRC risk.
