The U-shaped relationship between admission peripheral oxygen saturation and all-cause hospital mortality in acute exacerbation of chronic obstructive pulmonary disease: a retrospective analysis using the MIMIC III database

A U-shaped relationship between admission peripheral oxygen saturation and all-cause hospital mortality was observed in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The lowest mortality rate occurred at an SpO2 of 89.5%, indicating that lower oxygen levels are associated with increased risk.
