Objectives
RA
The objective of this post-hoc analysis was to determine whether patients on room air (RA) experience more OIRD episodes, compared with when receiving intermittent or continuous SO. Secondary objectives were to assess the type of OIRD episodes occurring in patients receiving intermittent or continuous SO or on RA, evaluate the association between OIRD episodes during intermittent or continuous SO or on RA as a function of PRODIGY score and finally, examine the frequency of OIRD episodes as a function of the time after the end of surgery.
