From: Admission vital signs as predictors of COVID-19 mortality: a retrospective cross-sectional study
Group | Method | Mean (SD) |
|---|---|---|
Total non-survivors | Pulse oximetry | 86 (9.94) |
ABG | 84.79 (10.9) | |
Oxygen saturation ≥ 90% | Pulse oximetry | 95.68 (3.18) |
ABG | 95.67 (3.01) | |
80% ≤ Oxygen saturation < 90% | Pulse oximetry | 85.87 (1.92) |
ABG | 85.33 (2.09) | |
Oxygen saturation < 80% | Pulse oximetry | 73 (4.45) |
ABG | 70.64 (5.54) |
