Prognostic value of arterial carbon dioxide tension during cardiopulmonary resuscitation in out-of-hospital cardiac arrest patients receiving extracorporeal resuscitation

Table 2 Multivariable logistic regression to favorable neurological outcome of variables with p-value < 0.15. The “No flow time” and “Arrest-ECMO time” were treated as continuous variables

Variable	Crude Odds Ratio	Adjusted Odds Ratio	95% C.I	p-value
No flow time	0.85	0.80	0.63—1.02	0.072
Arrest-ECMO time	0.96	0.99	0.97—1.02	0.678
PaCO2 (> 70 mmHg)	0.19	0.23	0.08—0.66	0.006
Witnessed Arrest	8.08	5.88	0.67—51.87	0.111
Rhythm change before ECMO	2.04	2.07	0.85—5.04	0.110
Shockable rhythm at hospital	2.96	2.05	0.79—5.27	0.138
Arrest location (at home)	2.47	2.62	0.88—7.79	0.084
