MYOCARDIAL INFARCTION
This randomized controlled study involving patients who received MV support in the ICU showed that: (I) there was a very strong positive linear relationship between ORi and PaOOxygen is considered a drug and should be used judiciously in patients who require it, as it has no beneficial effect on mortality. For instance, routine supplemental oxygen use did not reduce mortality in patients with suspected myocardial infarction without hypoxemia (Another question is whether adverse outcomes of hyperoxia are associated with high arterial peak oxygen levels or prolonged exposure to high PaORecent studies have suggested that the use of ORi, which can continuously and noninvasively measure oxygen levels, may effectively prevent hyperoxia (Similar to previous studies, our study showed that using ORi and SpOMoreover, the significant decrease in PaOSevere hyperoxia was observed approximately five times more frequently in the control group (24.8% vs 3.3%), while normoxia was observed approximately six times more frequently in the ORi+SpOAwareness is another crucial factor in preventing hyperoxia. A study of Dutch clinicians' responses to hyperoxia in ventilated patients showed that if FiOOur study has several limitations. First, the design was limited to a single center, which may have affected the generalizability of the results. Second, the time intervals chosen for data collection could have been more frequent, which would have given us a better understanding of the changes in the data over time. Third, while we observed differences in PaOIn conclusion, the combined use of ORi and SpOFunding None.Ethical approval granted by the Institutional Review Board and Ethics Committee of the Health Sciences University İzmir Tepecik Training and Research Hospital (01 12/08/2020)Declaration of authorship all authors conceived and designed the study; all authors acquired the data; all authors analyzed and interpreted the data; all authors drafted the manuscript; all authors critically reviewed the manuscript for important intellectual content; all authors gave approval of the version to be submitted; all authors agree to be accountable for all aspects of the work.Competing interests All authors have completed the Unified Competing Interest form at
