TABLE 3.
Blood gas analysis of recovery and death patients with severe or critical COVID-19.
| Characteristics | Normal range | Recovery (n = 60) | Death (n = 14) | P Value |
|---|---|---|---|---|
| pH | 7.35-7.45 | 7.44 (7.42-7.46) | 7.46 (7.41-7.47) | 0.197 |
| PaCO2, mm/Hg | 35-48 | 38 (34-43) | 34 (29-38) | 0.075 |
| PaO2, mm/Hg | 83-108 | 64 (52-77) | 57 (48-64) | 0.062 |
| PaO2:FiO2, mm/Hg (Admission) | 400-500 | 205 (145-263) | 131 (83-143) | <0.001 |
| PaO2:FiO2, mm/Hg (Discharged) | 400-500 | 303 (247-425) | 0 (0-0) | <0.001 |
| PaO2:FiO2, mm/Hg (Minimum) | 400-500 | 168 (116-227) | 59 (49-88) | <0.001 |
| SpO2, %, (Admission) | ≥ 93% | 93 (88-96) | 91 (85-94) | 0.116 |
| SpO2, %, (Minimum) | ≥ 93% | 90 (86-92) | 80.5 (63-85) | < 0.001 |
Data are reported as median (IQR). The P value represents the difference between COVID-19 recovery and death patients. P value <0.05 was considered significant difference (Bold font).
