Table 4 Associations between derangements and hospital mortality

From: Associations of arterial carbon dioxide and arterial oxygen concentrations with hospital mortality after resuscitation from cardiac arrest

Variable Unadjusted odds ratio (95 % CI) Adjusted odds ratio (95 % CI) P value
PaCO2 derangement vs. normocapnia 1.38 (1.24–1.54) 1.21 (1.07–1.36)a 0.003
PaO2 derangement vs. normoxia 1.45 (1.21–1.74) 1.27 (1.05–1.54)b 0.01
Interaction term - 1.07 (0.71–1.62) 0.75
  1. PaCO2 derangement = PaCO2 < 35 or PaCO2 > 45 mmHg; normocapnia = PaCO2 35–45 mmHg
  2. PaO2 derangement = PaO2 < 60 or PaO2 > 300 mmHg; normoxia = PaO2 60–300 mmHg
