Table 4 Predictors of successful discontinuation of mechanical ventilation for patients with COVID-19 ARDS

From: Effect of prone positioning on oxygenation and static respiratory system compliance in COVID-19 ARDS vs. non-COVID ARDS

Predictors (N = 23) Subdistribution hazard ratioa P value
Age (per 1 year) 1.18 (0.99–1.40) 0.063
Female sex (vs. Male sex) 13.92 (1.17–165.15) 0.037
SOFA score (per 1 point) 0.68 (0.49–0.95) 0.022
Charlson comorbidity index (per 1 point) 0.48 (0.17–1.39) 0.176
Baseline PaO2/FiO2 ratio (per 10 mmHg) 0.73 (0.53–1.00) 0.054
Baseline static respiratory system compliance (per 1 mL/cmH2O) 1.40 (1.10–1.79) 0.006
Increase in PaO2/FiO2 ratio after the first prone positioning session (per 10 mmHg) 1.19 (1.08–1.30) < 0.001
Increase in static respiratory system compliance after the first prone positioning session (per 1 mL/cmH2O) 1.57 (1.29–1.91) < 0.001
