ARDS Patient SpO2/FiO2 and PaO2/FiO2 Ratios from a High-Altitude Cohort in Xining, China

Table 1 from a retrospective cohort study by Jian Sun investigates the relationship between SpO2/FiO2 and PaO2/FiO2 ratios in patients with acute respiratory distress syndrome (ARDS). The dataset likely contains clinical data for 276 patients admitted to an ICU in Qinghai, China, between October 2020 and October 2024. It was published on figshare in May 2026 under a CC-BY-4.0 license.

Use Cases

• Validate the correlation between SpO2/FiO2 and PaO2/FiO2 ratios based on the study's findings.
• Assess the applicability of global ARDS diagnostic thresholds in high-altitude regions.
• Develop region-specific diagnostic criteria for hypoxemia severity based on the derived power function model.
• Analyze the performance of SpO2/FiO2 as a predictor for mild, moderate, and severe ARDS using the provided AUC and cutoff values.

Strengths

• Data is derived from a cohort of 276 ARDS patients.
• Study provides specific diagnostic thresholds and a power function model (SpO2/FiO2 = 5.661 × [PaO2/FiO2]^0.71).
• Focus on a high-altitude region (Xining, Qinghai) addresses a noted gap in validation.

Limitations

• Dataset is very small at 16.7 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
